The Omron R88D-1SAN30H-ECT is a 3kW servo drive from the 1SA family, designed for 240 VAC supply lines and controlled via EtherCAT. This drive brings functional safety integration to the Omron servo lineup, which means the safety functions (like STO) are handled over the EtherCAT network without separate safety relay wiring — a clean fit for a modern safety CPU separation architecture.
Sizing and selection
Omron's configuration guidance is to select the motor first, then match the drive. The 3 kW rating at 240 VAC means this drive is sized for a motor drawing roughly that shaft power; the actual motor current rating on the nameplate determines the correct drive frame. On a 240 VAC line, a 3 kW servo motor typically pulls around 12–14 A RMS under full load — the drive's continuous output current rating should be verified against the motor's rated current, not just the power number.
