Problems to be Solved by the Invention

[0006] Therefore, an object of the present invention is to improve the operability of a power tool.

Means for Solving the Problems

[0007] This problem is solved by a power tool according to claim 1. The operating device of the power tool includes a setting element configured as a rotary-pressure actuator for inputting parameter values, and a display unit for displaying the parameter values. [Effects of the Invention]

[0008] Depending on the configuration elements, parameter values ​​can be entered very easily. Based on the parameter values ​​displayed on the display unit, the user can verify whether the parameter values ​​have been entered correctly.

[0009] Any further advantageous configurations are subject to dependent claims.

[0010] The present invention further relates to a method for operating a power tool, the method comprising the step of inputting parameter values ​​via a setting element.

[0011] Further illustrative details and exemplary embodiments are described below in conjunction with the figures. [Brief explanation of the drawing]

[0012] [Figure 1] This is a schematic diagram of electrical equipment. [Figure 2] This is a perspective view of a power tool. [Figure 3] This is a schematic diagram of a power tool. [Figure 4] This is a schematic diagram of the operating device according to the first modification. [Figure 5] This is a schematic diagram of the operating device according to the second modified example. [Figure 6] This is a schematic diagram of a stack storage device. [Figure 7] This is a side view of a power tool. [Modes for carrying out the invention]

[0013] In the following description, the directions x, y, and z, which are orthogonal to each other and aligned within the figure, should be referred to. The x and y directions are horizontal directions, and the z direction is the vertical direction.

[0014] FIG. 1 shows an electric device 10, which is configured as a power tool, particularly as a saw device. The electric device 10 includes a functional unit 1, which is configured as a tool, particularly as a saw blade.

[0015] The electric device 10 includes an operating device 2, via which parameter values of at least one parameter related to the operation of the functional unit 1, particularly the tool, can be input. The at least one parameter includes, for example, the cutting depth (particularly as the first parameter) and / or the cutting angle (particularly as the second parameter). This operating device 2 can also be referred to as a man-machine interface.

[0016] The operating device 2 includes a setting element 3, which is preferably configured as a rotary-pressing actuator. The setting element 3 is used for inputting parameter values. Advantageously, at least two parameter values of at least two different parameters related to the operation of the functional unit 1 can be input via this setting element 3.

[0017] The rotary-pressing actuator is particularly configured as a rotary-pressing wheel. This rotary-pressing actuator is configured in a cylindrical shape for a purpose. This rotary-pressing actuator is supported rotatably about a rotation axis. For a purpose, the parameter value to be input by this rotary-pressing actuator, particularly one or more digits of the parameter value, can be increased in a first rotation direction by the rotation of this rotary-pressing actuator about the rotation axis. For practical purposes, the parameter values ​​to be input by this rotary-pressure actuator, particularly one or more digits of the parameter values, can be reduced in a second rotational direction by the rotation of the rotary-pressure actuator about the axis of rotation. This second rotational direction is opposite to the first rotational direction. The electrical device 10 is purposefully equipped with an incremental oscillator, which converts the rotational motion of the rotary-press actuator into an electrical signal, which is provided, for example, as an electrical operation signal. The rotary-press actuator can be pressed, for example, in the axial direction of the rotation axis, in order to select one or more digits of a parameter value to be input.

[0018] The operating device 2 further includes a display unit 4 for displaying at least one parameter value. Display unit 4 is, in particular, a graphic display, or more specifically, a pixel display. Display unit 4 is, for example, an LED or OLED display. Exemplaryly, display unit 4 has a resolution greater than 100 x 100 pixels, advantageously, a resolution of at least 240 x 240 pixels.

[0019] Advantageously, the operating device 2 further includes a selection element array 5 for selecting parameters as current input parameters. The current input parameter is the input parameter whose parameter value is currently inputtable, and in particular changeable, by the setting element 3. In particular, one parameter can be selected as the current input parameter from among several possible parameters via the selection element array 5.

[0020] Advantageously, the selection element array 5 comprises selection elements 6, 7, and 38. For the purpose of selecting each parameter as the current input parameter, each of the selection elements 6, 7, and 38 is assigned to its respective parameter. Advantageously, each of the selection elements 6, 7, and 38 is assigned to a display area of ​​the display unit 4, which is used for displaying the respective parameters, in particular, that are assigned to each.

[0021] For example, the selection element array 5 includes a first selection element 6, which is configured in particular as a first push button, and this first selection element allows a first parameter, such as cutting depth, to be selected as the current input parameter. The operation of the first selection element 6 selects the first parameter as the current input parameter, and therefore the parameter value of the first parameter (and in particular the parameter value of the second parameter) can be input via the setting element 3.

[0022] Advantageously, the selection element array 5 includes a second selection element 7, which is configured in particular as a second push button, and this second selection element allows a second parameter, such as the cutting angle, to be selected as the current input parameter. The operation of the second selection element 7 selects the second parameter as the current input parameter, and therefore the parameter value of the second parameter (and in particular the parameter value of the first parameter) can be input via the setting element 3.

[0023] Exemplary, the second selection element 7 is positioned below the first selection element 6, particularly such that the first selection element 6 and the second selection element 7 are aligned in a straight line in the y-direction and / or spaced apart in the z-direction. For practical purposes, the first selection element 6 and the second selection element 7 occupy the same region in the y-direction. The selection element array 5, in particular the first selection element 6 and / or the second selection element 7, are purposefully positioned beside the display unit 4, especially in the negative y-direction.

[0024] As already described above, the electrical device 10 is advantageously configured as a sawing device. Exemplary embodiments of the corresponding sawing device will be described in more detail below in reference to Figure 2.

[0025] First, other exemplary embodiments of the electrical device 10 should be described:

[0026] It is possible that the electrical device 10 is configured as, for example, a suction device, and the functional unit 1 is configured as a suction unit. In this case, at least one parameter is provided, in particular, for the suction performance of the suction unit.

[0027] The electrical equipment 10 may further be configured as a surface milling machine (Oberfraese) or a dowel milling machine (Duebelfraese), and the functional unit 1 may be configured as a milling machine. For example, at least one parameter in this case is (e.g., as a first parameter) the rotational speed of the milling machine and / or (e.g., as a second parameter) the milling depth of the milling machine. In other examples, at least one parameter comprises a first parameter of the milling program (for example, as a first parameter) and / or a second parameter of the milling program (for example, as a second parameter).

[0028] The electrical device 10 may further be configured as a light emitter, and the functional unit may be configured as a light-emitting means, such as an LED unit. For example, at least one parameter in this case is (for example, as a first parameter) the color temperature of the light-emitting means and / or (for example, as a second parameter) the brightness of the light-emitting means.

[0029] The electrical device 10 may further be configured as an audio output device, such as a radio, and the functional unit may be configured as a control unit for controlling the audio output. For example, at least one parameter in this case comprises (for example, as a first parameter) the volume of an audio output device, and / or (for example, as a second parameter) a station identifier assigned to a receivable station, and / or a playlist identifier assigned to a playable playlist.

[0030] Figure 2 shows a power tool 20, which is exemplary configured as a sawing device, particularly a table circular saw. This power tool 20 is an exemplary embodiment of the electrical equipment 10, and therefore embodiments relating to the electrical equipment 10 also apply to the power tool 20. In particular, the above description relating to the operating device 2 also applies to the operating device 2 of the power tool 20.

[0031] The power tool 20 is advantageously configured as a semi-fixed machine. A semi-fixed machine is a machine that is fixed in place for processing the workpiece 9 and can be transported by individual personnel.

[0032] The power tool 20 includes, as an example, a processing unit 12 configured as a saw unit. Specifically, this saw unit itself embodies a table circular saw. Selectively, the power tool 20 is further equipped with a cover hood 14, which can be mounted on the processing unit 12 and, advantageously, can be fixed to the processing unit 12. Advantageously, the power tool 20 is selectively movable between a work configuration and a transport configuration. In the work configuration, the cover hood 14 is removed from the machining unit 12, so that the workpiece 9 can be machined by the tool 8 of the machining unit 12. In the transport configuration, the cover hood 14 is placed on top of the machining unit 12 and, for the purpose, covers the tool 8 and / or workpiece mounting surface 18 of the machining unit 12.

[0033] The power tool 20, in particular the processing unit 12, is equipped with a tool 8, which is configured in particular as a saw blade. The tool 8 is one example of the functional unit 1 described above. The tool 8 is used for processing the workpiece 9. The saw blade is, exemplary, aligned with respect to the y-direction by the saw blade plane of the saw blade. The cutting direction of the saw blade extends, exemplary, parallel to the x-direction.

[0034] The power tool 20, in particular the machining unit 12, is equipped with a support structure 11, which, exemplary, has a rectangular parallelepiped base. The power tool 20, in particular the machining unit 12, is stationary on a base by the lower side of the support structure 11 (particularly aligned with respect to the negative z direction) so that the workpiece 9 can be machined in a specified working position by the tool 8. The support structure 11 exemplary embodies the outer housing of the machining unit 12.

[0035] The power tool 20 is equipped with a workpiece mounting surface 18 on which a workpiece 9 can be placed for processing by the tool 8. The workpiece mounting surface 18 is purposefully aligned in the direction normal to the positive z direction at the working position. Exemplarily, the workpiece mounting surface 18 is formed by the upper surface of the support structure 11. Exemplarily, the tool 8 can protrude upward from the support structure 11 through an opening provided in the workpiece mounting surface 18, and / or downward (in the negative z direction) into the support structure.

[0036] The power tool 20 is equipped with an operating device 2, which is configured in particular as already described above. The operating device 2 is purposefully positioned on the support structure 11, in particular on the first peripheral side surface 21 of the support structure 11. The operating device 2 is positioned particularly outside the support structure 11. The first peripheral surface 21 extends upward from the lower surface of the support structure 11 to the upper surface of the support structure 11. This first peripheral surface 21 extends, exemplary, parallel to the y-direction. This first peripheral side surface 21 is, in particular, a side surface from which the workpiece 9 can be pushed against the tool 8 in a feed direction parallel to the positive x-direction, in order to process the workpiece 9 with the tool 8. The operating device 2 is positioned in front of the tool 8 in the feed direction, in particular on a support structure or a portion of its surrounding side surface, such that the tool 8 is positioned inward in the y-direction of the operating device 2's y-extension, as shown in Figure 7.

[0037] For the purpose, in the transport configuration, the cover hood 14 completely covers the operating device 2, and therefore the operating device 2 is not operable in the transport configuration. In the working configuration, the cover hood 14 does not for the purpose of covering the operating device 2.

[0038] Figure 3 shows a schematic diagram of the power tool 20, particularly the processing unit 12.

[0039] The power tool 20 includes a control unit 15, which is located within the support structure 11. The control unit 15 includes, for example, a microcontroller. This control unit 15 is connected to the operating device 2 for information transmission. For the purpose of operation, the control unit 15 receives at least one electrical operating signal from the operating device 2. At least one electrical control signal is used to purposefully map the operation of the control device 2, in particular, the operation of the setting element 3 and / or the selection element array 5. The control unit 15 is purposefully connected to the display unit 4 for information transmission. For purposeful purposes, the control unit 15 outputs at least one electrical display signal to the display unit 4, particularly taking into consideration user input performed by the operating device 2, and especially taking into consideration at least one electrical operation signal.

[0040] For practical purposes, the power tool 20, in particular the machining unit 12, is equipped with a tool drive unit 16, which is used to drive the tool 8 into a machining motion, thereby machining the workpiece 9. The tool drive unit 16 is equipped with a drive electric motor for driving the tool 8. The machining motion is, exemplary, the rotational motion of the saw blade about a rotation axis that extends particularly parallel to the y-direction. The tool drive unit 16 is purposefully arranged within the support structure 11. For the purpose of determining the drive of the tool 8, the control unit 15 is configured to control the tool drive unit 16 by at least one drive signal, based on user input, particularly that performed by the operating device 2.

[0041] Advantageously, the power tool 20, in particular the machining unit 12, is equipped with a positioning device 17 having at least one electric motor for providing the moving motion (Verfahr-Bewegung) of the tool 8. The positioning device 17 is advantageously located within a support structure 11.

[0042] The power tool 20 is configured to perform moving motions for the purpose of repositioning the tool 8 and / or for the purpose of calibrating the tool 8.

[0043] The repositioning of the tool 8 is performed purposefully, relative to the workpiece mounting surface 18, and is used to determine first and / or second parameters, particularly the cutting depth and / or cutting angle.

[0044] Calibration movements are used for purposeful purposes to detect one or more reference positions, such as the maximum, minimum, and / or neutral position of the tool 8. For example, the tool 8 is moved to one or more reference positions during a calibration movement. For the purpose, the power tool 20 is not equipped with any absolute sensor for detecting the position of the tool 8, and / or is configured to incrementally determine the position of the tool 8, taking into consideration one or more reference positions that are detected in particular during calibration movement.

[0045] Exemplary, the positioning device 17 includes a first positioning electric motor 31 for setting a first parameter, in particular the height of the tool 8, in order to determine the cutting depth. Using this first positioning electric motor 31, the tool 8 can be positioned or moved in the z-direction for a purpose, particularly relative to the workpiece mounting surface 18. In particular, the tool 8 can be made to perform a first linear movement 41 using the first positioning electric motor.

[0046] Exemplary, the positioning device 17 includes a second positioning electric motor 32 for setting a second parameter, such as the angle of the tool 8, in particular for determining the cutting angle. Using this second positioning electric motor 31, the tool 8 is capable of purposefully rotating around a pivot axis extending particularly in the y-direction, or moving in a plane including the z-direction, perpendicular to the feed direction or the x-direction, particularly relative to the workpiece mounting surface 18. In particular, the tool 8 can be made to perform a second moving motion 42 using a second positioning electric motor 32. The second moving motion is advantageously a rotational motion.

[0047] Exemplary, the parameter value of the first parameter, particularly the cutting depth, can be changed by the selection of the first parameter, in particular, the cutting depth, as the current input parameter, and by the subsequent rotation of setting element 3. Advantageously, the power tool 20 is configured to position the tool 8 according to the parameter value, simultaneously with the change in the parameter value caused by the rotation of the setting element 3, using the first positioning electric motor 31.

[0048] For example, the parameter value of the second parameter, particularly the cutting angle, can be changed by the selection of the second parameter, in particular the cutting angle, as the current input parameter, and by the subsequent rotation of setting element 3. Advantageously, the power tool 20 is configured to position the tool 8 according to the changed parameter value, simultaneously with the change in parameter value caused by the rotation of the setting element 3, using the second positioning electric motor 32.

[0049] The rotation of setting element 3 causes, for the purpose of purpose, the parameter value of the current input parameter displayed on display unit 4 to change, and at the same time, the tool 8 is positioned by the positioning device 17 according to the displayed (changed) parameter value.

[0050] Advantageously, the power tool 20 is configured to perform the moving motion only while the operating device, in particular the setting element, is being operated, and to stop this moving motion when the operating device, in particular the setting element, is no longer being operated.

[0051] Advantageously, the power tool 20 is configured to perform a moving motion only when the tool 8 is not in a state of machining motion.

[0052] In particular, the control unit 15 is configured to continuously check whether the setting element 3 has been operated, for example, whether the setting element 3 has been rotated, based on electrical operating signals, and is configured to cause movement only while the setting element 3 is being operated by the control of the positioning device 17. Advantageously, the control unit 15 is configured to perform continuous inspection at a scan rate of at least 20 Hz, and preferably at least 100 Hz. The speed of the direct motion is, for example, at least 5 mm / second. In a modified example of an advantageous embodiment, the speed of the direct motion is, for example, 10 mm / second. The rotational velocity is, for example, 4 degrees / second. In a modified example of an advantageous embodiment, the rotational velocity is 6.5 degrees / second.

[0053] Advantageously, the operation of the operating device 2 is performed for the purpose of changing the parameter value, for example, increasing or decreasing the parameter value. Such a change in the parameter value is one example of inputting the parameter value. The power tool 20 is configured to position the tool 8 by moving motion according to a changed parameter value. Advantageously, the power tool 20 is configured to display the changing parameter value on the display unit 4 throughout the change in the parameter value and throughout the moving motion.

[0054] The user can increase or decrease the parameter value displayed on the display unit 4, in particular by rotating the setting element 3, and the power tool 20 moves the tool 8, and moreover, the parameter value displayed on the display unit 4, always depicts the current position of the tool 8, simultaneously with this increase or decrease.

[0055] For the automatic and / or electronically controlled movement (e.g., movement) of the saw blade of the power tool 20, user input (e.g., rotation of setting element 3) is required for the duration of the movement, thus in a purposeful manner.

[0056] In particular, the movement of the saw blade occurs only when setting element 3 is manipulated, and preferably when setting element 3 is rotated. Selectively, the intensity of the input (e.g., the rotational speed of setting element 3) has no effect on the movement speed.

[0057] For example, desired, particularly predetermined, or pre-defined tool positions, especially saw blade positions, e.g., parameter preset 39, standby position, and / or replacement position, can be selected (particularly via the operating device 2), and / or calibration movement can be selected. This calibration movement relates to a first parameter, particularly the cutting angle, and / or a second parameter, particularly the cutting depth, and is performed particularly by reaching the end position. The standby position is one position of the tool, particularly the saw blade, in which the tool, particularly the saw blade, is positioned sufficiently deep so that the cover hood 14 can be placed on and fixed in the processing unit 12. The replacement position is one position on the tool, in particular the saw blade, at which point the tool, in particular the saw blade, can be removed or replaced, in particular by the user.

[0058] The power tool 20 is configured to move only when the rotary-press actuator is rotated or pressed, and only while the rotary-press actuator is rotated or pressed, for the purpose of reaching a desired tool position, in particular the saw blade position, and / or for performing calibration movement of the tool, in particular the saw blade. Purposefully, this can reduce the risk of the user accidentally gripping the saw blade while moving in a small (portable, mobile, or handheld) saw device. Depending on the selective embodiment, the tool, in particular the saw blade, may be moved by input from another suitable user input element instead of input from a rotary-pressure actuator.

[0059] For the purposes of the operation, the power tool 20 is configured to stop the movement of the saw blade in response to the termination of user input (e.g., rotation or pressing of setting element 3) before the desired saw blade position is reached and / or the calibration movement is completed, and to output, in particular display, a (particularly optical) signal, in particular a fault notification, and / or prevent the saw blade from being driven, particularly via the display unit 4. The movement can be continued in a purposeful manner through further user input (for example, rotation or pressing of setting element 3).

[0060] As mentioned above, the movement is performed, in particular, within the range of calibration movement. Advantageously, the power tool 20 is configured to interrupt or stop the calibration movement if the rotary-pressure actuator is no longer rotated before the end of the saw blade's moving motion.

[0061] Selectively, the power tool 20, in particular the machining unit 12, is equipped with a communication interface 19 for communication with a mobile device 30. The mobile device 30 is, for example, a mobile phone or a tablet. Communication between the communication interface 19 and the mobile device 30 is advantageously performed wirelessly, particularly via Bluetooth, WLAN, mobile communication, and / or NFC.

[0062] For practical purposes, the power tool 20, in particular the machining unit 12, is equipped with a fan wheel 33, which is used in particular to generate airflow for cooling the power tool 20. The fan wheel 33 is purposefully connected to the tool 8, in particular so that the fan wheel 33 is driven together with the tool 8 by the tool drive unit 16. Advantageously, the power tool 20 is equipped with a cooling mode, in which the tool 8 is driven at a reduced rotational speed in order to cause cooling of the power tool 20 via the fan wheel 33 of the power tool 20 which is connected to the tool 8. The reduced rotational speed is reduced in particular compared to the machining speed used for machining the workpiece 9. The power tool 20 is configured to output, in particular display, a warning signal before entering a cooling mode, which indicates that the power tool 20 will enter a cooling mode, and / or to output, in particular display, a cooling mode signal during this cooling mode, which indicates that the power tool 20 is in a cooling mode. Warning signals and / or cooling mode signals are output and displayed, in particular, via the display unit 4, as timely notifications, especially as displayed on the display unit 4.

[0063] The operating device 2 will be described in more detail below. The operating device 2 described below is, in particular, the operating device 2 for the electrical equipment 10 and / or the power tool 20, especially the sawing device.

[0064] Advantageously, the operating device 2 has a tool drive operating device 34, through which the drive of the tool 8 for moving the tool 8 into machining motion can be switched on and / or switched off. The drive of the tool 8 is performed using a tool drive unit 16. For the purpose of this, the control unit 15 controls the tool drive unit 16 according to user input performed via the tool drive operating device 34. The tool drive operating device 34 includes, for example, a switch-on push button 35 for switching on the drive of the tool 8, and / or a switch-off push button 36 for switching off the drive of the tool 8. The tool drive operating device 34, in particular the switch-on push button 35 and / or the switch-off push button 36, are exemplary located on the first perimeter side surface 21. Exemplary, the tool drive operating device 34 is positioned beside the setting element 3, and in particular, to the right of the setting element 3. Exemplary, the switch-off push button 36 is positioned below the switch-on push button 35.

[0065] Advantageously, the power tool 20, in particular the machining unit 12, is further equipped with a main on / off switch 37, via which the power tool 20, in particular the operating device 2, can be switched on and / or switched off. For the purpose of this, the power tool 20, in particular the control unit 15, can be turned off by operating the main on / off switch 37, and in this off state, the drive of the tool 8 cannot be switched on via the tool drive operating device 34. The main on / off switch 37 is, exemplary, positioned at a distance from the tool drive operating device 34. The main on / off switch 37 is, exemplary, positioned on the second periphery side surface 22 of the support structure 11. The second periphery side surface 22 extends, exemplary, parallel to the x-direction.

[0066] Advantageously, the display unit 4 is configured to display a first parameter value 51 of the first parameter and a second parameter value 52 of the second parameter. The first parameter value 51 is, in particular, the current value of the first parameter, and the second parameter value 52 is, in particular, the current value of the second parameter. For example, display unit 4 displays parameter values ​​51 and 52 one above the other. For practical purposes, display unit 4 displays these parameter values ​​as numerical elements, particularly through numerical representations, such as Arabic numerals.

[0067] Advantageously, the first selection element 6 is positioned spatially in correspondence with the first parameter value 51, and / or the second selection element 7 is positioned spatially in correspondence with the second parameter value 52. For example, the first selection element 6 occupies a first z-region, and the first parameter value 51 is located within this first z-region. For example, the second selection element 7 occupies a second z-region, which is different from the first z-region, and the second parameter value 52 is located within this second z-region. For the purpose, the first z-region, the first selection element 6, and / or the first parameter value 51 are positioned exclusively above a virtual straight line extending in the y-direction, and / or the second z-region, the second selection element 7, and / or the second parameter value 52 are positioned exclusively below a virtual straight line extending in the y-direction.

[0068] Figure 4 shows the operating device 2 according to the first modified example. This operating device is also referred to as the first operating device 2A. The operating device 2 includes, exemplary, at least two, in particular two, selection elements 6 and 7, which together have the same vertical extension as the display unit 4 and are aligned flush with the display unit 4 in the vertical direction.

[0069] For example, the power tool 20 is configured as a handheld circular saw or a table circular saw, and the first parameter is, for example, the cutting depth and / or the second parameter is the cutting angle.

[0070] Furthermore, the power tool 20 may be configured as a cross-cut saw, and the first parameter may be, for example, the angle of the bevel joint (Gehrungswinkel), and / or the second parameter may be, for example, an inclination angle (particularly one that can be adjusted perpendicularly to this angle of the bevel joint).

[0071] Figure 5 shows the operating device 2 according to the second modified example. This operating device is also referred to as the second operating device 2B.

[0072] For example, the selection element array 5 further includes a third selection element 38, specifically configured as a third push button, which allows selection of a third parameter as the current input parameter. The operation of the third selection element 38 selects the third parameter as the current input parameter, and therefore the parameter value of the third parameter can be input via the setting element 3.

[0073] The operating device 2 includes, exemplary, at least three, in particular three, selection elements 6, 7, and 38, which together have the same vertical extension as the display unit 4 and are aligned perpendicularly to the display unit 4.

[0074] Advantageously, the display unit 4 is configured to display the third parameter value 53 of the third parameter, which is, in particular, the current value of the third parameter.

[0075] Advantageously, the third selection element 38 is spatially corresponding to the third parameter value 53. For example, the third selection element 38 occupies a third z-region distinct from the first and second z-regions, and the third parameter value 53 is located within this third z-region.

[0076] Purposefully, the third z-region, the third selection element 38, and / or the third parameter value 53 are positioned exclusively below a second virtual straight line extending in the y-direction, and / or the first z-region, the first selection element 6, and / or the first parameter value 51, and / or the second z-region, the second selection element 7, and / or the second parameter value 52 are positioned exclusively above a second virtual straight line extending in the y-direction.

[0077] For example, the power tool 20 is configured as a handheld circular saw or a table circular saw, and the first parameter is, for example, the cutting depth, and / or the second parameter is the cutting angle, and / or the third parameter is the rotational speed of the saw blade.

[0078] Advantageously, setting element 3 has two input modes. Both of these input modes are advantageously comprised of a press input mode and a non-press input mode. In press input mode, the setting element 3 rotates while being pressed by the user, particularly in the direction of the axis of rotation around which the setting element 3 can rotate. In non-press input mode, the setting element 3 rotates while not being pressed, particularly in the direction of the axis of rotation of the setting element. Advantageously, one of the input modes, for example, the non-pressure input mode, is used for inputting at least one decimal place of the parameter value of the current input parameter, and / or the other input mode, for example, the pressure input mode, is used for inputting at least one decimal place of the parameter value of the current input parameter. For practical purposes, one input mode allows input of multiple, particularly all, decimal digits of the parameter value, and / or the other input mode allows input of multiple, particularly all, digits above the decimal point of the parameter value. For practical purposes, one input mode, particularly the non-pressure input mode, allows input exclusively of one or more decimal digits (and, in particular, no digits beyond the decimal point), and / or, the other input mode, particularly the pressure input mode, allows input exclusively of one or more decimal digits (and, in particular, no digits beyond the decimal point). The control unit 15 is configured to interpret, for the purpose of its function, the rotation of the setting element 3 when it is not pressed as input to one or more decimal places of a parameter value, and / or the rotation of the setting element 3 when it is pressed as input to one or more decimal places of a parameter value.

[0079] In a selective embodiment, the setting element 3 is rotated in press input mode while the selection element, which is assigned to the parameter selected as the current input parameter, is pressed.

[0080] Advantageously, all inputtable parameter values ​​can be entered via the setting element 3—and therefore, particularly via the rotary-pressure actuator. For practical purposes, the power tool 20 does not have any touchscreen, letter keys (Buchstabenblock), or numeric keys (Ziffernblock) for inputting parameter values.

[0081] Advantageously, the main menu can be accessed by pressing setting element 3 twice. The main menu comprises multiple menu elements, which are displayed on display unit 4, particularly vertically. For the purpose of the system, one menu element can be selected from multiple possible menu elements via the rotation of setting element 3, and the selection of a menu element can be confirmed by pressing setting element 3.

[0082] Advantageously, the power tool 20 is configured to simultaneously display multiple selectable parameter presets 39 on the display unit 4. The parameter presets 39 are also referred to as favorite parameters or parameter presets. Advantageously, each parameter preset 39 can have the parameter values ​​for all parameters selectable by the selection element, particularly all parameters selectable by the selection element. Advantageously, each parameter preset 39 can have two parameter values ​​for two different parameters. The parameter values ​​of the parameter preset 39 are also referred to as preset parameter values. For practical purposes, the parameter preset 39 is displayed on the display unit 4, above and below each other, in particular, beside the first parameter value 51 and / or the second parameter value 52 and / or (if present) the third parameter value 53. For practical purposes, the parameter preset 39 is displayed simultaneously with the parameter values ​​51, 52 and / or 53. In particular, the parameter presets 39 are displayed as a list on the display unit 4. This list extends for practical purposes across the entire height of the display unit 4. Exemplarily, at least two, at least three, or at least four parameter presets 39 are displayed on the display unit 4 simultaneously.

[0083] Selectively, each parameter preset 39 is intended to have only one parameter value for a single parameter. Purposefully, each parameter preset 39 is located within the z-region of the selection element to which each parameter preset 39 is assigned in this case.

[0084] Advantageously, all existing parameter presets 39 are not displayed simultaneously, and / or can be scrolled through by all existing parameter presets 39 via the rotation of the setting element 3.

[0085] Selectively, depending on whether the power tool 20 is not positioned in a standby position, and therefore the cover hood 14 cannot be precisely mounted on and / or fixed to the machining unit 12 based on the current position of the tool, in particular the saw blade, a standby position symbol may be displayed on the display unit 4, and the tool, in particular the saw blade may be configured to be movable to the standby position via the selection of this standby position symbol. The standby position symbol may be displayed, for example, within the list of pre-set settings 39. Selectively, the power tool 20 may be configured not to display a standby position symbol, depending on whether the tool, particularly the saw blade, is in a standby position, and therefore the cover hood 14 can be precisely mounted on and / or fixed to the machining unit 12.

[0086] As illustrated in Figure 4, each parameter preset 39 may include a first parameter, for example, a first preset parameter value for the cutting depth, and / or a second parameter, for example, a second preset parameter value for the cutting angle. Each parameter preset 39 is displayed on the display unit 4, specifically as a numerical element, above and below each other, by displaying the preset parameter value that belongs to each parameter preset 39.

[0087] As illustrated in Figure 5, each parameter preset 39 can selectively have up to three preset parameter values, and these preset parameter values ​​are displayed above and below each other in a purposeful manner.

[0088] Advantageously, the currently set parameter values ​​can be stored as parameter presets 39 by simultaneously pressing at least two selection elements—for example, a first selection element 6 and a second selection element 7. The currently set parameter values ​​are, in particular, the currently displayed first parameter value 51, and / or the currently displayed second parameter value 52, and / or (if any) the currently displayed third parameter value 53.

[0089] Advantageously, one of the currently set parameter values ​​can be deselected by pressing the assigned selection element, so that the currently set parameter value is not stored together with the parameter preset 39. Selectively, the deselection of a parameter value can be reversed by pressing the assigned selection element again.

[0090] The memory location of a new parameter preset 39 to be stored, particularly within a list, can be determined via the setting element 3, particularly solely via the setting element 3, in order to selectively select the memory location, especially by rotation of the setting element 3, and by subsequent pressing of the setting element 3 to confirm the selection.

[0091] Selectively, the power tool 20 is configured to receive at least one parameter preset from the parameter presets 39 from the mobile device 30 via the communication interface 19. Advantageously, the power tool 20 includes, for example, personalized parameter presets received from the mobile device 30, and, for example, unpersonalized parameter presets not received from the mobile device 30. For practical purposes, the power tool 20 is configured to handle personalized parameter presets differently from unpersonalized parameter presets. For example, the power tool 20 is configured to display personalized parameter presets and / or not display unpersonalized parameter presets while connected to the mobile device 30. For example, after the connection with the mobile device 30 is terminated, the power tool 20 is configured to no longer display personalized parameter presets and / or display unpersonalized parameter presets.

[0092] Advantageously, the parameter presets 39 can be scrolled via the rotation of the setting element 3 to select one parameter preset 39, and the selected parameter preset 39 can be activated by pressing the setting element 3. When the parameter preset 39 is activated, the preset parameter values ​​of the selected parameter preset are set as the first parameter value 51, the second parameter value 52, and (if any) the third parameter value 53.

[0093] Advantageously, the power tool 20, in particular the control unit 15, is configured to convert the rotation of the setting element 3 into a scroll of the parameter preset 39 when no parameter is selected as the current input parameter.

[0094] Selectively, the power tool 20 has a passive operating mode in which the tool 8 is not movable for machining motions to process the workpiece 9. For example, the control unit 15 brakes the drive of the tool 8 (particularly the drive provided via the tool drive unit 16) in the passive operating mode. In the passive operating mode, the power tool 20 displays usage instruction information via the display unit 4 to inform the user of the proper handling of the power tool 20. The power tool 20 also has an active operating mode in which the tool 8 is movable during machining. For example, in this active operating mode, the control unit 15 releases the drive of the tool 8 via the tool drive unit 16. Selectively, the control unit 15 automatically causes the power tool 20 to first occupy a passive operating mode when the power tool 20 is started to operate—particularly when the power tool 20 is first switched on—and then, for the purpose of confirming one or more displayed usage instructions by operating the setting element 3, it switches to an active operating mode only after such operation.

[0095] Advantageously, the power tool 20 is configured to indicate the passive operating mode and / or active operating mode by the respective display operating mode of the display unit 4, in particular by the respective background brightness. For example, the control unit 15 sets the background brightness of the display unit 4 to be darker in the passive operating mode than in the active operating mode. This background brightness represents, for example, the brightness of the hue of the background color. For example, the control unit 15 sets the hue of the background color of the display unit 4 to be darker in the passive operating mode than in the active operating mode.

[0096] Advantageously, the power tool 20 is equipped with a display-stack storage device 43. Figure 6 shows a schematic diagram of an exemplary display-stack storage device 43 in three different states. The display-stack storage device 43 is operated by software, for example, particularly within the control unit 15.

[0097] Within the display stack storage device 43, the notification targets 44A, 44B, and 44C are stored in advance, and these notification targets are assigned to the respective notifications, particularly fault notifications, that should be displayed on the display unit 4. In the first state shown on the left, the first reportable object 44A and the second reportable object 44B are pre-held in the display-stack storage device 43. In the second state shown in the center, a third reportable object 44C is further added in the display-stack storage device 43. In the third state shown on the right, only the second reportable object 44B exists in the display-stack storage device 43.

[0098] The power tool 20 is configured to display, in particular to display in its entirety, any notification that is assigned to a notification object located in a first position within the display stack memory 43. This notification is also referred to as the current display notification. For practical purposes, the power tool 20 is configured not to display other notifications—i.e., notifications assigned to notification objects not located in the first position—and / or to display them only partially, for example, partially obscured by the current display. In the state shown on the left, the power tool 20 displays all of the notifications assigned to the first notification target object 44A (located in the first position) on the display unit 4, and either does not display the notifications assigned to the second notification target object 44B, or displays only a portion of them. In the state shown in the center, the power tool 20 displays all of the notifications assigned to the third notification target object 44C (located in the first position) on the display unit 4, and either does not display the notifications assigned to the other notification target objects 44A and 44B, or displays only partially them. In the state shown on the right, the power tool 20 displays all the notifications assigned to the second notification target object 44B (located in the first position) on the display unit 4.

[0099] For the purpose, the power tool 20 removes the notification object located in the first position from the display-stack storage device 43 in response to confirmation input performed by the operating device 2 (particularly by the user), so that each lower notification object is shifted forward by one position. Confirmation input is performed, for example, by setting element 3, specifically by pressing this setting element 3. For example, in the transition from the state shown in the center of Figure 6 to the state shown on the right, the confirmation input is first performed for the third notification object 44C located in the first position, thereby removing the third notification object 44C from the display-stack storage device 43, and shifting the first notification object 44A and the second notification object 44B forward by one position, so that the first notification object 44A is located in the first position. Next, confirmation input is performed for the first notification object 44A, which is now located in the first position, thereby removing the first notification object 44A from the display-stack storage device 43, and shifting the second notification object 44B forward by one position, so that the second notification object 44B is located in the first position.

[0100] For the purpose, the power tool 20 is configured to set an object assigned to a further notification in a first position within the stack storage device 43 in accordance with a predetermined phenomenon that triggers yet another notification, and to shift each of the objects that previously existed in the stack storage device 43 one position backward. The predetermined phenomenon is recognized by the control unit 15 and is, for example, an error phenomenon. For example, in the transition from the state shown on the left in Figure 6 to the state shown in the center, a predetermined phenomenon occurs that triggers one notification assigned to the third notification target 44C, and consequently, this third notification target 44C is set to the first position in the stack memory device 43, and the notification targets 44A and 44B that were previously in this stack memory device are each shifted one position backward.

[0101] The control unit 15 is configured to always display the most recent notification on the display unit 4, and to cover up one or more previously displayed notifications with this most recent notification. For the purpose, the control unit 15 is configured to remove the most recent notification in response to a confirmation input performed by the operating device 2, and to display the notification that was previously obscured by the most recent notification that was removed.

[0102] The power tool 20 can be operated by one method, which comprises the step of inputting parameter values ​​via a setting element 3.

[0103] Advantageously, firstly, through the operation of the first selection element 6, the first parameter is selected as the current input parameter. Then, for the purpose of, the parameter value of the current input parameter—that is, the first parameter—is changed by the rotation of the setting element 3, and is input in this way. For example, in order to change one or more decimal places of a parameter value and to input it, firstly, setting element 3 is rotated in non-pressure input mode. This parameter value is, on the other hand, displayed on display unit 4. Advantageously, the power tool 20 positions the tool 8 according to the changed (and currently displayed) parameter values ​​throughout the rotation of the setting element 3. As soon as the rotation of the setting element 3 is completed, the power tool 20 stops the movement of the tool 8 that was performed for the purpose of positioning the tool 8. For example, in order to change one or more decimal places of the parameter value and to input it, the setting element 3 is rotated in press input mode. This parameter value is, on the other hand, displayed on the display unit 4. Advantageously, the power tool 20 positions the tool 8 according to the changed (and currently displayed) parameter values ​​throughout the rotation of the setting element 3. As soon as the rotation of the setting element 3 is completed, the power tool 20 stops the movement of the tool 8 that was performed for the purpose of positioning the tool 8.

[0104] For the purpose of the operation, the second parameter is then selected as the current input parameter through the operation of the second selection element 7. The input of the parameter value is then performed for the purpose of the operation, in the same manner as described in relation to the parameter value of the first parameter.

[0105] Selectively, the power tool 20 may be operated by one method, which involves the following steps: - Prior retention of items 44A, 44B, and 44C subject to reporting, These reported items are assigned to the respective reports that should be displayed on the display unit 4, especially the fault reports. - Display - In the stack memory, the display of the notification is assigned to the notification target located at the first position. - Removal of the notification target object located at the first position from the stack storage device 43 in response to the confirmation input performed by the operating device 2, Therefore, each of the lower-level reporting targets is shifted forward by one position. and / or, - Depending on a predetermined phenomenon that triggers further reports, A set of notification objects assigned to yet another notification at a first position within the stack storage device 43, and Prior to that, each of the reported objects existing in the stack memory had one position, moving backward.
