Working Principle The drive operates as a CANopen slave node on an industrial control network. The host controller (PLC or motion controller) sends motion commands, parameters, and control words via CANopen service data objects and process data objects. The internal processor interprets these commands and executes the corresponding motion profiles while reporting status, actual position, and velocity back to the network. Current, velocity, and position loops are closed locally within the drive for optimal performance.
Installation Requirements
- Connect to CANopen network with proper cable shielding and termination
- Configure node address via rotary switches or software
- Ensure CAN bus baud rate matches network configuration
- Provide isolated 24VDC logic power if required by network topology
Operating Precautions
- Verify CANopen node ID does not conflict with other network devices
- Monitor CAN bus error counters for communication integrity
- Configure emergency stop behavior via CANopen fault reaction parameters
- Maintain network cable integrity to prevent communication dropouts
