Harmonic Drive REL EtherCAT AC Servo Drives
REL is an AC-line servo-drive family with CANopen over EtherCAT command communication and configuration-specific actuator feedback support. Harmonic Drive documents REL combinations with identified FHA, SHA, RSF and RKF actuators rather than offering an unrestricted promise of compatibility with every motor bearing those family names. Select the drive, winding, encoder and cable set as one approved axis.

Review Summary
Consider REL when an AC-powered EtherCAT axis and a documented actuator-drive combination match the machine architecture. Separate the drive’s output-current rating from actuator demand and line-supply current. EtherCAT connectivity alone does not establish feedback compatibility, thermal capacity, brake sequencing or a complete safety function.
