Omron R88D-1SN08H-ECT 1S Series 800W EtherCAT Servo Drive 230V Single‑Phase

Omron R88D‑1SN08H‑ECT is a high‑performance AC servo drive in the 1S series, featuring built‑in EtherCAT communications for precise motion control in industrial automation applications. Rated output 800 W (0.75 kW) at 230 V single‑phase input. Designed to work with 1S series AC servomotors (R88M‑1L and R88M‑1M series) for integrated motion control, the drive supports high‑resolution 23‑bit multi‑turn absolute encoder without battery backup, a new innovative control loop (TDF), and dual‑layer Safe Torque Off (STO) safety functions. Pluggable connectors and screwless push‑in terminals simplify pre‑wiring and system maintenance. IP20 enclosure.
