Working Principle
The S30661-NA receives 3-phase AC input power at 110V to 230V, converts it to DC bus voltage, and drives the brushless servo motor through its power stage. The cascaded digital control loops (current, velocity, position) provide precise torque, speed, and position control. The feedback device monitors the motor’s rotor position and speed, and the drive continuously adjusts the supplied current and voltage to correct any deviations from the commanded motion.
Installation Requirements
- Mounting inside a closed switchgear cabinet
- Proper EMC-compliant grounding and shielding for all cables
- External fusing required for AC supply protection
- 3-phase AC supply within the 110V to 230V range at 50-60 Hz
- Suitable external brake resistors must be selected from Kollmorgen’s accessories if internal braking capacity is insufficient
