Product Overview
The Omron R88M-1M20030H-S2 is the 200 W high-inertia member of Omron's 1S-series servo family — a 60 mm flange-face, 11 mm shaft, 23-bit incremental encoder servo motor purpose-built for belt-driven conveyors, ball-screw stages, and other loads with significant reflected inertia. 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. Specifications on this page were checked against Omron's Accurax servo datasheets.
The 'H' suffix in R88M-1M20030H vs 'T' suffix in R88M-1M20030T distinguishes high-inertia from low-inertia: this SKU (H) carries roughly 2× the rotor inertia, which smooths out step-and-direction motion and provides better rejection of low-frequency load disturbances. The encoder is a 23-bit (8,388,608 pulse/rev) optical incremental unit — a battery-less absolute version would have a 'C' suffix (R88M-1M20030C-S2).
The 1S (R88M-1M) family replaced the G5 (R88M-K) family in 2021 as the workhorse compact servo line.
Key Features
- 200 W rated output, 230 VAC single-phase supply
- 60 mm flange face, 11 mm shaft diameter, with keyway option
- 23-bit incremental encoder on this SKU
- Pairs with R88D-1SN02H-ECT 1S-series EtherCAT drive
- SKU: R88M-1M20030H-S2
- Series: R88M-1M (1S-series servo motor family)

Best-Fit Applications
- Inline labeler drive for product orientation and feed-roller positioning on packaging lines
- Pick-and-place Z-axis on chip mounters where short-stroke peak acceleration is needed and a holding brake is required
- Belt-driven conveyor tracking — high-inertia rotor smooths indexing motion at 1–2 kg load inertia
Buying Checklist
- Pick the R88M-1M20030H-BS2 for any vertical axis where the load must not free-fall on power removal
- Pick the R88M-1M20030H-S2-Z for Simulink-compatible drive profiles
- Pick the R88M-1M20030C-S2 when the application needs absolute multi-turn position

FAQ for R88M-1M20030H-S2
What's the difference between the R88M-1M20030H-S2 and the T-suffix variant?
Both are 200 W EtherCAT 1S servo motors, but the rotor inertia differs — the H (high inertia) variant has roughly 2× the rotor inertia of the T (low inertia) variant. The H variant smooths step-and-direction motion and reduces low-frequency load-disturbance amplification — best for belt-driven conveyors, ball-screw stages, and any application where load inertia approaches rotor inertia. The T variant accelerates faster from standstill and reverses faster — best for chip mount and short-stroke machine axes.
What drive does this motor pair with?
The R88D-1SN02H-ECT — 1S-series 200 W EtherCAT drive, single-phase 230 VAC input. The drive handles the motor's 0.637 Nm continuous torque and 2.2 Nm peak torque at 3000 rpm. For servo systems that need Simulink-compatible drive profiles for model-based design, use the R88D-1SN02H-ECT-Z variant (-Z suffix = Simulink profile). For STO safety, the drive supports FSoE STO PL d via EtherCAT when wired through an NX-SL5500 safety controller.
What cables do I need to order with the motor?
Two cables are mandatory: (1) the power cable — R88A-CRGB001-5-E1R for 1 m, or longer for longer distances. (2) the encoder cable — R88A-CRGBE001-5-E1R for 1 m, or longer. The bare motor (this SKU) does not include cables — Omron sells the cable separately to avoid useless stocking of wrong-length cables. For the brake option -BS2 you also need the R88A-CRGB-RA-LEP brake lead. For washdown / oil-mist environments upgrade to the -5B1 (IP67 robot cable) version of each cable.
Can I use this motor with an Accurax G5 drive instead of a 1S drive?
No — the 1S (R88M-1M) and G5 (R88M-K) servo motors use different encoder protocols and different winding designs. The 1S requires an R88D-1S or R88D-1S@-ECT drive; pairing a 1S motor with a G5 drive will not synchronise the encoder and the drive will report a 'motor type mismatch' fault at commissioning. Similarly, do not pair a G5 motor (e.g. R88M-K20030H-S2) with a 1S drive.
