The Omron R88D-1SN02H-ECT is a 200 W servo drive from the 1S series, fed by single-phase 230 VAC (170–252 V range) and communicating over EtherCAT. It drives a matching 200 W rotary servo motor — typically the R88M-1M20030(H/T) frame — with a 23-bit absolute encoder for position loops that settle without overshoot. Rated current is 2.7 A, and the drive carries built-in Safe Torque Off (STO) rated PLd (EN ISO 13849-1) and SIL2 (IEC 61508) over the network, plus a hardwired STO channel. That means the safety function lives inside the drive — no external safety relay needed for the stop circuit.
The drive measures 40 mm wide, 180 mm tall, and 185 mm deep — a slim footprint that fits standard 35 mm DIN-rail or panel-mount layouts. IP20 rating means it belongs inside a cabinet, not on the machine frame. All connectors are screw-less push-in type; I/O and the motor brake relay are pluggable for pre-wiring and swap-out without re-terminating the harness. Operating temperature range is 0 °C to 55 °C, so derate if the cabinet ambient runs above that. The single-phase input draws from L and N; no third-phase wiring to worry about, which simplifies panel layout for smaller machines.
200 W rated power matches a 200 W servo motor — pairing a larger motor would overload the drive output stage. The 2.7 A rated current is the continuous output limit; short-term peak current during acceleration is higher but thermally limited by the drive's I²t algorithm. Single-phase 230 VAC input means the drive cannot run on three-phase supply without a step-down transformer or phase converter. Verify your line voltage is within 170–252 VAC before committing the BOM line.
