The Omron R88D-KN20H-ECT is a G5-Series servo drive rated for 20 kW continuous output on a 200 VAC three-phase supply, with EtherCAT communications onboard. This is the high-power end of the G5 family — sized for a 20 kW servo motor, not a general-purpose VFD. The EtherCAT interface is fixed; no option-card swap to other fieldbuses.
The 20 kW rating is the continuous output capacity at the drive's rated switching frequency — this governs motor sizing, not peak torque. On a 200 VAC line, a 20 kW servo motor typically draws around 70–80 A RMS at full load; verify the drive's continuous current spec against your motor nameplate. The EtherCAT port runs at 100 Mbps, standard for motion networks; no gateway needed if the controller is also EtherCAT-native.
