[0044] In this embodiment, the mounting frame 310 covers the electrical components of the device body 100. It can be understood that the mounting frame 310 is arranged on the housing 110 or the front cover 120. Taking the mounting frame covering the front cover 120 as an example, a cavity is formed by enclosing between the mounting frame 310 and the front cover 120, and electrical components are provided in this cavity.

[0045] Further, the panel 320 mainly includes a panel body and a display screen. The panel body is usually made of metal or high-strength plastic, which is used to protect the internal electronic components and circuits, and at the same time provides mounting and operation interfaces. The fasteners 321 and the positioning parts 322 are arranged on the panel body. Usually, the fasteners 321 and the positioning parts 322 are integrally formed with the panel body. The display screen is used to display the operation status, fault information, parameter settings, etc. The display screen can be an LED display screen, an LCD display screen or a touch screen. In some embodiments, buttons or knobs may be provided around the display screen. In some embodiments, the panel 320 may not have a display screen and only has buttons or knobs, etc.

[0046] In one embodiment, in order to improve the mounting stability of the panel 320, the number of the fasteners 321 is multiple, and the multiple fasteners 321 are arranged in an array. Among them, the number of the fasteners 321 can be four, five, six, seven, eight or more than eight, and no specific limitation is made here. Of course, in other embodiments, the number of the fasteners 321 can be two or three.

[0047] Regarding the arrangement of the multiple fasteners 321 in an array, the following will be described in detail:

[0048] Multiple fasteners 321 are arranged in a linear array: The fasteners 321 are arranged in a straight line, which is usually used for fixing long strip or rectangular panels 320.

The square positioning column is used in cooperation with the corresponding square positioning groove 312, which can prevent rotation and sliding and provide stronger anti-torsion ability. When the positioning part 322 is a square positioning column, a guiding surface is provided at one end of the positioning part 322 away from the panel 320. At this time, it can also be called a positioning rib.

[0056] In another embodiment, in order to improve the stability of the installation of the panel 320, the number of the positioning parts 322 is multiple, and the multiple positioning parts 322 are arranged in an array on the installation frame 310.

[0062] In one embodiment, the device body 100 includes a mounting bracket 130, a housing 110 and a front shell 120. The mounting bracket 130 includes a bracket body 131 and a bottom plate 132 provided on the bracket body 131. The housing 110 is arranged to cover the bracket body 131. The bottom plate 132 and the front shell 120 are arranged on opposite sides of the bracket body 131. The mounting frame 310 is rotatably and switchably arranged on the side of the front shell 120 facing away from the housing 110. Exemplarily, the mounting frame 310 has a first end and a second end arranged opposite to each other in a first direction. The first end of the mounting frame 310 is rotatably connected to the front shell 120, and the second end of the mounting frame 310 is detachably connected to the front shell 120.

[0063] Regarding the first direction and the second direction, exemplarily, the first direction is generally the length direction of the front shell 120, and the second direction is the width direction of the front shell 120. In some embodiments, the first direction may be the vertical direction, and the second direction is the horizontal direction of the front shell 120.

[0064] Among them, the front shell 120 usually further has operation buttons and knobs, connection interfaces (electrical interfaces, including power interfaces, communication interfaces (such as RS232, RS485, CAN, etc.) and signal interfaces (such as analog input / output, digital input / output, etc.), used for connecting to external devices and systems), and labels and identifications (device models, specification parameters, safety prompts, etc., facilitating user identification and operation), etc. In this embodiment, arranging the panel assembly 300 on the front shell 120 can make it more convenient for users to operate.

[0065] In addition, the mounting frame 310 is rotatably and switchably arranged on the side of the front shell 120 facing away from the housing 110. Users can conveniently rotate the mounting frame 310 to replace or maintain the panel 320. This can significantly reduce the complexity and time of disassembling and assembling the panel 320, and improve work efficiency. The rotatable mounting frame 310 allows the panel 320 to be adjusted at different angles, meeting the requirements of users for the angle and position of the panel 320 in different application scenarios. This design increases the flexibility and adaptability of the device. Secondly, when it is necessary to inspect and maintain the components inside the mounting frame 310, only need to rotate the mounting frame 310 and remove the panel 320, without disassembling the entire device body 100, thus simplifying the maintenance process and reducing the interference to the device.

[0066] In one embodiment, the servo drive device 10 further includes a battery compartment 121. The opening 122 of the battery compartment 121 is arranged on the front shell 120. The battery compartment 121 is integrally formed with the front shell 120.

[0084] Generation of drive signal: The servo drive device 10 calculates the required drive current or voltage according to the command signal and outputs it to the servo motor.

[0085] Execution of motor movement: The servo motor executes the corresponding movement tasks (rotation or linear movement) according to the drive signal.

[0086] Obtaining of feedback signal: The feedback device measures the actual movement state of the motor and feeds back this data to the servo drive device 10.

[0087] Closed-loop control adjustment: The servo drive device 10 adjusts the drive signal in real time according to the difference between the feedback signal and the command signal to improve the movement accuracy and response speed of the motor.

[0088] In the above embodiment, the panel of at least part of the servo drive devices is set as a display panel with a display screen. Since the display screen can display the working state of the servo drive device in real time, such as the rotation speed, position, torque, current working mode, etc. of the motor, it enables the operator to immediately understand the operating condition of the equipment, discover and handle abnormal situations in time, and improve the stability and reliability of the system.
