Servo motor is an important executive structure in robots, mechanism and electronics and (aeromodellings.) Servomotor controller supplies necessary power and control signals.

A servo control system composed of PMAC2 controller, servo controller, servomotor and industrial control computer has been developed for carbon fibre production to control the draft ratio precisely.

The system use the STM32 as the core controller. The control of servomotor can be achieved walking and lifting of the picking platform.
