Working Principle The controller receives motion commands via serial communication or analog inputs, processes the commands through digital control loops, and generates PWM signals to drive the servo actuator’s motor. It uses resolver or encoder feedback from the actuator to close the position and velocity loops, ensuring accurate positioning and smooth motion. The current loop regulates motor current to deliver precise torque control.

Installation Requirements

  • Mount vertically on panel with M4 screws
  • Maintain 50 mm clearance on all sides for cooling
  • Use shielded cables for motor and feedback connections
  • Connect protective earth terminal to system ground
  • Install in dry, dust-free electrical cabinet
  • Separate power wiring from signal wiring by minimum 100 mm

Usage Notes

  • Do not connect or disconnect motor cables while power is applied
  • Perform auto-tuning procedure at initial commissioning
  • Ensure actuator model matches controller configuration
  • Do not exceed maximum ambient operating temperature
  • Keep ventilation vents clear of obstruction
  • Follow proper ESD procedures when handling internal components
