Application cases of integrated stepper servo motors in pre-processing equipment
Application scenarios
A customer in Suzhou selected our integrated stepper servo motor in the pre-processing equipment to improve the accuracy and operating efficiency of the equipment. As a key pre-processing link in the medical industry, the pre-processing equipment has extremely high requirements for the control accuracy and stability of the motor.
Selected models and functions
Selected models:
- STM5776B-CANopen-M
- STM4260B-CANopen-ME-0FS
- STM2851B-CANopen
Functions used:
- Blocked rotor return to origin
- PP (position mode)
- CSP mode
Problems and challenges encountered
1. The sound of the blocked rotor return to the origin is too loud, and the motor will heat up: During the operation of the equipment, it was found that the motor produced a loud sound when the blocked rotor returned to the origin, and the motor had obvious heating, which affected the stable operation and life of the equipment.
2. The speed of the STM5756B-CANOPEN-M motor in position mode cannot be increased: During the debugging process, the technicians found that the running speed of the STM5756B-CANOPEN-M motor in position mode could not reach the expected speed, which limited the working efficiency of the equipment.
Solution
For the above problems, we provide the following solutions:
1. Optimize the parameters of the stall return to origin:
Reduce the speed of the stall return to origin H6099-02 to 5000 to reduce the load and friction of the motor during the stall process.
Reduce the stall detection time from 400ms to 10ms to improve the motor's response speed to the stall and reduce unnecessary energy consumption and heat generation.
2. Adjust the motor speed setting:
Check the parameter settings of the STM5756B-CANOPEN-M motor and find that the maximum speed is incorrectly set to 50RPM.
Adjust the maximum speed to the appropriate range to ensure that the motor can operate normally in position mode and reach the expected speed.
Application effect
After the above adjustment and optimization, the pre-processing equipment has achieved significant application effects:
- The motor runs more smoothly: The sound and heating phenomenon when the motor returns to the origin after blocking have been significantly improved, and the motor runs more smoothly and reliably.
- Improved work efficiency: The running speed of the STM5756B-CANOPEN-M motor in position mode has reached the expected speed, and the overall work efficiency of the equipment has been improved.
- Equipment stability is enhanced: By optimizing parameter settings, the stability and reliability of the equipment have been enhanced, reducing the failure rate and maintenance costs.
Case summary
The integrated stepper servo motor was successfully applied in the pre-processing equipment. By optimizing parameter settings and debugging, the problems of the motor in the stall return to the origin and position mode speed were solved. This application case fully demonstrates the advantages and application potential of the integrated stepper servo motor in the pre-processing equipment of the medical industry, and provides a useful reference and reference for similar projects.
