Can you send me the schematic diagram? My project is to control the servo motor with a single chip microcomputer. My email address is: zhangguobinnly@163.com, thank you!

Judging from the neatness of the soldering on your terminal blocks, the workmanship is very poor. I wonder why anyone wants it.

1． The most compact DC servo drive! ◇ Input voltage DC12～48V, maximum continuous current 5A, peak current 10A◇ Continuous output power 200W, overload capacity 400W◇ Compact size: 70×50×19 mm2. 2. The most practical function! ◇ Step pulse (CLK+DIR) mode control. The frequency of the pulse corresponds to the speed of the motor, and the number of pulses corresponds to the displacement of the motor (corresponding to the quadruple frequency of the encoder resolution); ◇ PWM speed control. Duty cycle50%motor braking, greater than50%motor forward rotation, less than50%motor reverse rotation.

3． The safest driver! ◇ Driver internal temperature monitoring, with over-temperature and under-temperature protection. ◇ PWM switching frequency up to 62.5KHz, higher efficiency, less motor heat, more effective protection of the motor

◇ Overcurrent protection

◇ Overvoltage protection

◇ Undervoltage protection

◇ Failure protection

◇ Overload protection

◇ Tracking error over-limit protection◇ Encoder fault identification, etc.4. Simple operation! ◇ Use RS232 interface to set parameters and debug PID. ◇ PID parameters are stored digitally, no potentiometer needs to be adjusted, which can ensure consistency and efficiency in production. Our company provides free software "Operation Control Servo Management System", which can conveniently set parameters and debug PID of the driver. The debugging effect can be intuitively seen through the curve!

6． Application fields:

Digital engraving machine, textile machine, embroidery machine, mold engraving machine, robot, peristaltic pump, blood analyzer, packaging machine, precision machine tool, filling machine, etc. qq670501245 029-88223597-802 15091898990 www.mlarm.com Ms. Wang

I want to make an AC servo driver now, but I have no idea how to start. I don't know how to make the circuit. Oh, it's really difficult. I hope the experts can give me some advice. Thank you!
