Product Overview
The Omron R88D-1SN08H-ECT is a 1S-series 750 W EtherCAT AC servo drive in a 65 mm wide chassis, manufactured by Omron Corporation. Hengyixin Automation ships this drive from Xiamen with the matching motor or PSU pairing recommended in the related products row below.
The drive accepts single-phase or three-phase 200-240 VAC at 7.3 A or 4.0 A respectively, with a separate 24 VDC control input at 600 mA for the logic board. Output is 0 to 240 V three-phase variable frequency at 4.6 Arms continuous, sized for the R88M-1M75030T 750 W 3000 rpm 2.39 Nm motor. EtherCAT runs at 125 microseconds to 10 ms DC cycle, with ECAT IN and ECAT OUT RJ45 ports for ring topology.
Safety is hardwired STO to EN ISO 13849-1 PL e and FSoE STO to PL d. Programming uses Sysmac Studio. The IP20 open-chassis unit is 226.5 mm tall, weighs 2.0 kg, and panel-mounts inside an IP54 cabinet.
Key Features
- 1S-series EtherCAT AC servo drive, 750 W (0.75 kW) output power
- Single-phase or 3-phase 200-240 VAC main, 24 VDC 600 mA control input
- EtherCAT 125 microseconds to 10 ms DC cycle with CiA 402 drive profile
- Hardwired STO (PL e) and FSoE STO (PL d), IP20 open chassis, 2.0 kg
- SKU: R88D-1SN08H-ECT
- Series: Omron 1S-series AC servo drive, EtherCAT built-in
Best-Fit Applications
- Sysmac NJ or NX cabinet 750 W motion axis where the EtherCAT ring runs at 125 microseconds sync cycle on a 200-240 VAC supply
- Pick-and-place or packaging line where the matching R88M-1M75030T 750 W motor drops onto the same 1S drive without rework
- Spare replacement for a legacy SmartStep 2 or Accurax G5 drive where the new 1S upgrade gives 23-bit battery-less absolute encoding
Buying Checklist
- Choose the R88D-1SN08H-ECT when the cabinet needs a 750 W EtherCAT drive in the 1S family with hardwired STO safety.
- Choose the R88D-1SN04H-ECT instead for a 400 W axis on the same 1S family and EtherCAT cycle.
- Choose the R88D-KN08H-ECT-Z instead when the existing cabinet is on the Accurax G5 family and like-for-like spare replacement matters.

FAQ for R88D-1SN08H-ECT
What motor pairs with the R88D-1SN08H-ECT?
The R88M-1M75030T 750 W 3000 rpm 2.39 Nm 1S motor with 23-bit battery-less absolute encoder is the direct match. The drive also accepts the R88M-1M75030H-S2 with keyway and oil seal, or the 1M75030T-BS2 with brake but straight shaft, for a vertical axis where the brake holds at power-off.
Does the R88D-1SN08H-ECT support three-phase 200-240 VAC?
Yes. The drive accepts both single-phase and three-phase 200-240 VAC (170-252 V) at 50 or 60 Hz. Single-phase draws 7.3 A at 240 V, three-phase draws 4.0 A. The control logic is powered from a separate 24 VDC input at 600 mA and stays live even when the main is off.
What is the difference between R88D-1SN08H-ECT and R88D-1SN08H-ECT-51?
The -51 suffix adds SS1 and SLS safety sub-functions in addition to STO, delivered over FSoE. The base R88D-1SN08H-ECT provides hardwired STO to PL e and FSoE STO to PL d only. Pick the -51 variant when the cabinet needs distributed safe stop and safe-limited-speed functions over the same EtherCAT ring.
What software does the R88D-1SN08H-ECT use?
Sysmac Studio version 1.20 or later, the same software used for NJ and NX controllers. The USB CN7 console port on the front face also accepts MR Configurator2 for offline tuning. ESI files for the EtherCAT master are downloadable from the Omron EU product page.
