Working Principle
The S20330 receives 20 to 90VDC input power and drives the brushless servo motor through its power stage. The drive’s digital signal processor executes current, velocity, and position control loops at 1.25MHz update rate. High-resolution 24-bit encoder feedback provides precise rotor position information. The 5kHz current loop bandwidth and 800Hz velocity loop bandwidth ensure smooth motion and rapid response. The intelligent feedback system with electronic motor nameplate enables plug-and-play commissioning by automatically configuring drive parameters.
Installation Requirements
- Suitable for DIN rail or panel mounting
- Ensure adequate ventilation for heat dissipation
- EMC-compliant shielding and grounding
- Use specified cable types and sizes
- Connect “Keep Alive” power input for rapid emergency stop recovery
