Product Overview
The Omron R88M-K2K030H-S2-Z is the 2 kW member of Omron's Accurax G5 servo-motor family, sitting between the 1.5 kW R88M-K1K530H-S2-Z and the 3 kW R88M-K3K030H-S2-Z in the 200 V class lineup. 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 6.37 Nm of rated torque at 3000 rpm and can briefly reach 19.1 Nm peak (300 % of rated) for fast acceleration and deceleration profiles, which is the envelope that packaging, material-handling, and converting machinery actually demand from a 2 kW axis. The 20-bit incremental encoder (H in the part number) gives 1,048,626 pulses per revolution — more than enough resolution for cut-to-length, registration, and indexing applications where the master controller reads absolute position through a homing sequence at startup.
For commissioning, load the Z-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 a few seconds once the motor is bolted to its load.

Buying Checklist
- Pick R88M-K2K030H-BS2-Z if the axis is vertical and needs a holding brake for power-off safety
- Pick R88M-K2K030C-BS2 or R88M-K2K030F-BS2 if your drive bus is 400 V three-phase
- Pick R88M-K2K030H-S2-Z for a 2 kW 200 V axis with 20-bit incremental encoder and no brake

FAQ for R88M-K2K030H-S2-Z
What drive pairs with the R88M-K2K030H-S2-Z?
Any G5-series drive rated for 2 kW at 200 V three-phase. The most common pairings are R88D-KN20H-ECT-Z (EtherCAT, for NJ501 / NX102 controllers) and R88D-KT20H-Z (Mechatrolink-II or pulse-train, for CJ2 or standalone applications). Do not mix 200 V motors with 400 V drives — the bus voltage, encoder cable, and parameter set are different.
Does the R88M-K2K030H-S2-Z come with a brake?
No. The S2 suffix in the part number means straight keyed shaft, no brake. If the axis is vertical and you need a holding brake for power-off safety, order the R88M-K2K030H-BS2-Z instead — same motor, but with a 24 VDC spring-engaged holding brake rated to hold the rated torque when de-energised.
What's the difference between H and T suffix on Accurax G5 motors?
H = 200 V class with 20-bit incremental encoder. T = 200 V class with 17-bit absolute encoder that retains position through power cycles via a battery in the encoder cable. Pick H if your controller can home the axis on every start (typical for most packaging and material-handling lines). Pick T if you want to skip homing at restart (typical for machines with limited travel that power down in safe positions).
What's the -Z suffix mean on the R88M-K2K030H-S2-Z?
The -Z suffix indicates the motor ships with a Sysmac Studio electronic data sheet matched to its electrical and mechanical parameters, so Sysmac Studio auto-detects the motor when connected via EtherCAT and pre-loads the torque limits, inertia ratio, encoder resolution, and thermal model. You can still use a non-Z motor on the same drive — you just enter the parameters manually in the drive's setup screen.
