Filling international and domestic gaps. Background Art

[0002] Existing stepper motor control or servo motor control usually requires users to adjust the speed to achieve a specified movement distance or time. This method is not only cumbersome, but also difficult to achieve precise timing and precise distance. Therefore, being able to directly input the target time and distance without speed adjustment has become a technical problem. At present, there is no control system or controller that can directly input the running time and travel distance, and can automatically adjust the speed according to the input. There is a gap in this technology in the domestic and foreign markets that needs to be filled.

[0003] Therefore, the market is in urgent need of a new controller that can automatically control the motor movement according to the input time and distance, meet the requirements of high-precision operation, and is easy to operate and suitable for most application scenarios. Summary of the invention

[0004] The present invention provides a stepper motor servo motor controller that can achieve precise timing and distance determination. The user only needs to input the required running time and distance, and the controller will automatically control the motor to ensure that the specified task is completed accurately, without manual speed adjustment, and the task is completed at a uniform speed (except for the instantaneous acceleration when starting and the instantaneous deceleration when stopping). It fills the gaps in the international and domestic markets and is a pioneering and innovative invention.

[0005] In order to solve the above problems, the present invention provides a "stepping motor servo motor controller capable of both precise timing and precise distance determination", and its main technical solutions are as follows: Input settings: The user enters two parameters through the controller's interface: Time setting (0-99 hours 59 minutes 59 seconds) Distance setting (0.01mm to 99999.99mm) The controller will automatically control the motor based on these two parameters to ensure that the motor can accurately complete the set distance in the set time.

[0006] Operation interface: The controller is equipped with a liquid crystal display (5) showing four lines (17)(18): The first line: the currently set distance, the format is: distance: xxxxx.xxmm, the unit is mm, accurate to two decimal places, the distance setting range: 0.01mm to 99999.99mm; The second line: the currently set time (or the countdown during operation), the format is: time: xxhxxmxxs, the unit is hours, minutes, seconds, the time setting range is: 0-99 hours 59 minutes 59 seconds; The third row: not shown (can be used for future expansion); Fourth line: Motor running status (forward / reverse, stopped / started).

[0007] Button functions: The controller is equipped with 8 buttons (6), which are used to set direction, adjust parameters, start / stop and other functions: Button 1: Switch movement direction (forward or backward) Button 2: + Current setting parameter (time or distance) Button 3: - Current setting parameter (time or distance) Button 4: Enter the setting state and adjust the parameters Button 5: Start or stop the motor Button 6: Alternate function Button 7: Fast rewind (press and hold) Button 8: Fast forward (press and hold) Note: When setting parameters, if the set distance and time exceed the physical maximum speed of the motor, the controller will automatically jump back to the first setting item; The settings are completed and the parameters are automatically saved.

[0008] Internal and external drivers: This controller has a built-in stepper motor driver, which supports direct use of stepper motors with current ≤3A. This controller also supports external drivers to drive stepper motors or servo motors of any power, improving the compatibility and scalability of the system.

[0009] Power input: DC9-24V, 1-3.5A (depending on the load).

[0010] The controller adopts a transparent shell (4), the style of which is shown in the attached drawings. Due to the refraction and reflection of light, the shell in the real photo looks translucent, but it is actually completely transparent. On the contrary, the simulation picture is closer to the real effect and is beautiful.

[0011] This controller has multiple expansion ports reserved: (1)(2)(3)(7)(10)(11)(12)(13)(14)(15) to facilitate the expansion of other functions.
