Product Overview
The Omron R88D-1SN08H-ECT is the 1S-series EtherCAT drive for 200 V 750 W servo motors. Pick it on a new Sysmac build when the cabinet needs a compact 200 V / 750 W servo on the same EtherCAT ring as the NJ / NX motion controller.
The drive accepts single-phase or 3-phase 200-240 VAC main power (170-252 V) at 7.3 A single / 4.0 A 3-phase at 240 V, plus a 24 VDC control supply (21.6-26.4 V) at 600 mA. Output is 0-240 V variable-frequency 3-phase at 4.6 Arms continuous and 16.9 Arms peak. The dedicated absolute encoder port reads 23-bit battery-less ABS encoders (no battery to replace) at up to 6,000 rpm mechanical.
On the front face: OMRON wordmark, RUN / ERR / L/A IN / L/A OUT LEDs, two EtherCAT RJ45 ports (ECAT IN / ECAT OUT) for daisy-chain, an ADR rotary for the drive address, the CN7 mini-USB console port, and a push-in spring terminal block (L1 / L2 / L3 main + L1C / L2C control) on the bottom. EtherCAT runs at 100BASE-TX with a 125 us to 10 ms communications cycle in DC mode (sync with Sync0 event). The CiA 402 drive profile covers cyclic-synchronous position / velocity / torque, profile position / velocity, homing, touch-probe, and torque limit. Sysmac Studio is the configuration environment.
Safety is built in via the hardwired STO input (Safe Torque Off) per EN ISO 13849-1 Cat 3 PL e / EN 61508 SIL 3. For distributed safety over EtherCAT (STO / SS1 / SS2 / SLS / SDI / SOS / SLP), move to the R88D-1SN08H-ECT-S2 (1S-series with FSoE) or the Accurax G5 R88D-KN08H-ECT-Z on existing G5 cabinets.
The paired motor at 750 W 3,000 rpm is R88M-1M75030T (23-bit battery-less ABS). Approvals: CE / UKCA / ULus (IND. CONT. EQ. 7Z45) / TUV / KC / RCM / EAC, China RoHS, SEMI F47 momentary-power-interruption hold at rated output. Weight 2.0 kg, open-chassis IP20 (mount in a IP54 cabinet).

Best-Fit Applications
- Sysmac NJ / NX cabinet motion axis at 750 W on a 1-phase or 3-phase 200-240 VAC supply
- Packaging, assembly, or pick-and-place machine where the drive sits on the same EtherCAT ring as the motion controller
- Skid-mount machine where the new 1S drives replace older SmartStep 2 / Accurax G5 units at 750 W 200 V
- Scara or delta robot where the 125 us cycle and CiA 402 cyclic-synchronous modes need a 23-bit battery-less encoder
- Battery-free machine upgrade -- the 23-bit battery-less ABS encoder removes the absolute-encoder battery maintenance
- Distributed safety via FSoE (when upgraded to R88D-1SN08H-ECT-S2) or via a separate safety controller
Buying Checklist
- Pick the R88D-1SN08H-ECT when the cabinet needs a 750 W EtherCAT drive in the 1S-series family
- Pick the R88D-1SN02H-ECT instead for a 200 W axis on the same family
- Pick the R88D-1SN04H-ECT instead for a 400 W axis
- Pick the R88D-1SN08H-ECT-S2 when the build also wants FSoE distributed safety (STO / SS1 / SS2 / SLS / SDI / SOS / SLP) over EtherCAT
- Pick the R88D-KN08H-ECT-Z instead when the cabinet is on the Accurax G5 family and like-for-like spare replacement matters
- Pair the drive with R88M-1M75030T (750 W 3,000 rpm 23-bit battery-less ABS motor) for the matching axis

FAQ for R88D-1SN08H-ECT
Is the R88D-1SN08H-ECT the same as the Accurax G5?
No. The R88D-1SN[] is the Omron 1S-series EtherCAT drive -- the standard 200 V entry in the new 1S line with STO safety. The Accurax G5 family is the R88D-KN[] (e.g. R88D-KN08H-ECT-Z). They share a similar housing but the 1S line adds the 23-bit battery-less ABS encoder, the improved loop control, and simplified push-in terminals. Pick 1S for new Sysmac builds; pick G5 as a like-for-like spare on existing G5 cabinets.
What motor pairs with the R88D-1SN08H-ECT?
The 750 W 3,000-r/min R88M-1M75030T 1S-series servomotor with a 23-bit battery-less ABS encoder is the matching axis. Higher-inertia (low-speed high-torque) variants in the R88M-1M family pair to the same drive at the same power class; confirm the encoder code matches (the battery-less ABS is the B / T suffix on the 1S motor).
Does the R88D-1SN08H-ECT carry functional safety over EtherCAT?
The bare -ECT has STO via the hardwired safety input signal (EN ISO 13849-1 Cat 3 PL e / EN 61508 SIL 3). It does not carry FSoE safety on top -- for distributed safety over EtherCAT (STO / SS1 / SS2 / SLS / SDI / SOS / SLP), step up to the R88D-1SN08H-ECT-S2 or the Accurax G5 R88D-KN08H-ECT-Z. Both add FSoE on top of the basic STO.
What software programs the R88D-1SN08H-ECT?
Sysmac Studio, the same IDE that programs the NJ / NX controller. The drive appears in the Sysmac Studio EtherCAT configuration as a CiA 402 drive profile device, with axis setup, autotuning, and safety parameter download through the tool. No separate drive-only software is required for normal commissioning.
