Product Overview
The Omron R88D-KN08H-ECT-Z is a 200 V single-phase Accurax G5-series AC servo drive with built-in EtherCAT communications, rated at 750 W output. It is 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.
65 x 150 x 242 mm panel-mount chassis at ~1.6 kg (3.6 lbs) Position, speed, or torque control per axis with 2 kHz high-response frequency
Position, speed, or torque control per axis with 2 kHz high-response frequency 65 x 150 x 242 mm panel-mount chassis at ~1.6 kg (3.6 lbs)
Mount in a cabinet with the R88A-FIK107-SE RFI filter for CE EMC compliance.
Key Features
- Position, speed, or torque control per axis with 2 kHz high-response frequency
- 65 x 150 x 242 mm panel-mount chassis at ~1.6 kg (3.6 lbs)
- Add R88A-FIK107-SE RFI filter (sold separately) for CE EMC compliance at 230 VAC
- Accurax G5-series 200 V single-phase EtherCAT AC servo drive (NOT SmartStep 2 -- SmartStep 2 is the R7D-BP[] family)
- SKU: R88D-KN08H-ECT-Z
- Series: Accurax G5 EtherCAT AC servo drive
Best-Fit Applications
- Pair with the R88M-K75030T-S2 absolute motor for battery-free multi-turn position retention
- Indexing table drive where the G5 high-response tuning gives smooth 90-degree moves
- Pick-and-place axis on a packaging machine driven from an NJ / NX EtherCAT motion master
Buying Checklist
- Pick the R88D-KN02H-ECT-Z or R88D-KN04H-ECT-Z instead for 200 W / 400 W axes in the same G5 family
- Pick the R88D-KN10H-ECT-Z instead for 1 kW 200 V single-phase (the next step up in the same family)
- Pick the R88D-KN08H-ECT-Z for a 200 V single-phase 750 W EtherCAT servo axis on an NJ / NX cabinet

FAQ for R88D-KN08H-ECT-Z
What is the difference between R88D-KN08H-ECT-Z and R88D-1SN08H-ECT?
The R88D-KN08H-ECT-Z is the 750 W Accurax G5 drive; the R88D-1SN08H-ECT is the 750 W 1S-series drive (the G5 successor). Both are 200 V single-phase EtherCAT drives with the same rated output, but the 1S-series runs a newer tuning suite (Sysmac Studio with 1S-series device profiles) and has a built-in 23-bit battery-less absolute encoder interface. Pick the G5 (KN08H) for like-for-like spare replacement on an existing Accurax G5 cabinet; pick the 1S (1SN08H) for new builds.
Does the R88D-KN08H-ECT-Z have SS1 or SLS safety?
No. The bare KN[]-ECT series carries STO (Safe Torque Off) only via dedicated safety input wiring. For SS1 (Safe Stop 1), SLS (Safely-Limited Speed), or other advanced safety functions, step up to the -L variant (R88D-KN08H-ECT-L) which adds the safety expansion card. For FSoE distributed safety over EtherCAT, pick the 1S-series -S2 variant (R88D-1SN08H-ECT-S2).
What motor does the R88D-KN08H-ECT-Z drive?
Omron R88M-K75030H-S2 (750 W, 3,000 rpm, incremental encoder, 2.4 Nm) is the standard pick. For absolute-encoder multi-turn position retention, pick the R88M-K75030T-S2 (same motor, absolute encoder (T suffix)). For a brake axis, pick the H-BS2 or T-BS2 variants (the BS2 suffix adds a 24 VDC brake). All four R88M-K75030[] motors are on the Accurax G5 lineup at the same 750 W axis class.
Does the R88D-KN08H-ECT-Z include the connector kit?
Yes -- the -Z suffix is a logistics code meaning the drive ships with the connector kit (M4 ring-lug power terminals, 24-pin I/O connector, encoder connector). The bare R88D-KN08H-ECT (no -Z) is the same drive without the kit and is intended for bulk orders where the panels already have the connectors. Add the R88A-FIK107-SE RFI filter for CE EMC compliance at 230 VAC.
