Working Principle The drive accepts 120 to 240 VAC input and rectifies it to an internal DC bus. Digital signal processors execute current, velocity, and position control algorithms at high update rates. Three-phase sinusoidal current is synthesized using space vector PWM techniques. The SynqNet interface exchanges real-time command setpoints and status data with a motion controller over a deterministic FireWire-based network. The intelligent feedback device with electronic motor nameplate enables plug-and-play commissioning by automatically configuring motor parameters.
Installation Requirements
- Mount in ventilated electrical enclosure with IP20 protection minimum
- Connect to 120/240 VAC supply with proper overcurrent protection
- Use shielded FireWire cables for motor feedback connections
- Install SynqNet network with proper termination at both ends
- Ensure adequate panel spacing for convective cooling
Operating Precautions
- Verify input voltage selector settings match local supply voltage
- Configure motor parameters to match connected motor rating plate
- Monitor SynqNet network integrity through status indicators
- Enable proper fault handling for overtravel and emergency stop conditions
- Maintain backup of drive parameter settings before network reconfiguration
