The system controller (MCU) output PWM is converted to 0-5V or 0-10V voltage output by GP8101 after optocoupler isolation. 2. The 0-5V/0-10V voltage is converted into PWM signal by GP9303, and then input to the inverter or motor driver for motor speed regulation after optocoupler isolation.

thanks! That sound perfekt I just ordered a Acorn Controller to retrofit my Emco PC Turn 55 now

I also encountered this problem, thank you for your suggestion.
