Product Overview
The Omron R88M-K20030H-S2 is the 200 W member of Omron's Accurax G5 servo-motor family — the entry point in the 200 V class lineup, sitting between the 100 W R88M-K10030H-S2 and the 400 W R88M-K40030H-S2. 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.
It delivers 0.64 Nm of rated torque at 3000 rpm with a peak torque of 1.91 Nm (300 % of rated) for fast acceleration and deceleration profiles, more than enough for the small-format packaging, labelling, indexing, and pick-and-place stations that typically use a 200 W axis. The S2 suffix describes the shaft and brake: S2 = straight shaft with keyway, no brake.
For commissioning, load the G5-series electronic data sheet (EDS) in Sysmac Studio; the motor's torque, inertia, and encoder parameters populate automatically, and the auto-tuning routine adjusts the velocity / position gains in seconds once the motor is bolted to its load.

Buying Checklist
- Pick R88M-K40030H-S2 for the next step up at 400 W
- Pick R88M-K20030H-BS2 if the axis is vertical and needs a 24 VDC holding brake
- Pick R88M-K20030H-S2 for a 200 W 200 V axis with 20-bit incremental encoder and no brake

FAQ for R88M-K20030H-S2
What drive pairs with the R88M-K20030H-S2?
Any G5-series drive rated for 200 W at 200 V single phase. The most common pairings are R88D-KN02H-ECT (EtherCAT, for NJ501 / NX102 controllers) and R88D-KT02H (Mechatrolink-II or pulse-train, for CJ2 or standalone applications). For 400 V three-phase drives, order the 400 V variant R88M-K20030F-S2 and pair it with an R88D-KN02F-ECT drive.
Does the R88M-K20030H-S2 come with a brake?
No — the S2 suffix means straight keyed shaft, no brake. If the axis is vertical and you need a holding brake for power-off safety, order the R88M-K20030H-BS2 instead — same motor, but with a 24 VDC spring-engaged holding brake rated to hold the rated torque when de-energised.
What is the difference between H, T, F, and C encoder suffixes?
H = 200 V + 20-bit incremental encoder. T = 200 V + 17-bit absolute encoder with battery backup. F = 400 V + 20-bit incremental. C = 400 V + 17-bit absolute. Pick H for the most common case (a 200 V axis that homes on every start). Pick T when you want to skip homing at restart. Pick F or C if your drive bus is 400 V three-phase.
What IP rating is the R88M-K20030H-S2?
IP65 on the motor body and cable connector face — dust-tight and protected against low-pressure water jets. The shaft seal is splash-proof, not submersible. For food-processing or outdoor applications where the motor may be hosed down, fit an Omron IP67 cable gland kit and mount the motor with the connector facing down.
