Product Overview
The R88M-1M75030H-S2 is the 750 W member of Omron's Accurax 1S servo-motor family, the next-generation platform that succeeds the G5 series with a more compact body, higher encoder resolution, and battery-free multi-turn absolute encoder option. It delivers 2.39 Nm of rated torque at 3000 rpm with a peak torque of 8.4 Nm (350 % of rated) for fast acceleration and deceleration profiles — more headroom than the G5 family at the equivalent power. The 23-bit incremental encoder (H in the part number) gives 8,388,608 pulses per revolution, the highest resolution in Omron's 1S range, suitable for applications demanding sub-micron positioning accuracy such as semiconductor handling, precision assembly, and high-end packaging.
1S series vs G5 series
The Accurax 1S series (R88M-1) is the current-generation servo motor that supersedes the G5 series (R88M-K) for new designs. Compared to the equivalent G5 motor, the 1S has higher peak torque (350 % vs 300 %), higher encoder resolution (23-bit vs 20-bit), smaller body length for the same power, and battery-free multi-turn absolute encoder option. The 1S also adds Safe Torque Off (STO) integrated into the R88D-1SN drive as standard, simplifying safety wiring for new installations. Pick R88M-1M75030H-S2 (1S, this SKU) for new Sysmac-platform designs with NJ501, NX102, or NX1P controllers.
Mechanical integration and applications
The R88M-1M75030H-S2 has an 80 × 80 mm flange (LC dimension) and uses a 70 mm pilot diameter, the standard for 750 W class servo motors. Total length is approximately 124 mm without brake and weight is around 2.5 kg — compact for a 750 W axis. The shaft is 19 mm diameter with a keyway and a tapped M6 × 12 hole on the end for coupling attachment — use a flexible jaw coupling (Omron R88A-CSK series) or a zero-backlash servo coupling.

Buying Checklist
- Pick R88M-1M75030H-S2 for 750 W 200 V 1S-series axis with 23-bit incremental encoder and no brake
- Pick R88M-1M75030H-BS2 if the axis is vertical and needs a 24 VDC holding brake
- Pick R88M-1M75030T-S2 if you need absolute position retention through power cycles
- Pick R88M-1M75030F-S2 if your drive bus is 400 V three-phase
- Pick R88M-K75030H-S2 only for compatibility with existing G5 wiring and drives
- Order the R88A-CSK19S flexible coupling matched to the 19 mm shaft

FAQ for R88M-1M75030H-S2
What drive pairs with the R88M-1M75030H-S2?
The 1S-series drive R88D-1SN08H-ECT (EtherCAT) for new installations. For 400 V three-phase panels, use the R88D-1SN08F-ECT. Do not pair the 1S motor with a G5-series drive (R88D-KN08H-ECT) — the motor parameter sets and encoder feedback protocols differ.
What is the difference between R88M-1M75030H-S2 and R88M-K75030H-S2?
Same 750 W power, same 3000 rpm speed, same 200 V drive, same S2 (no brake) shaft. The 1S (R88M-1) is the current-generation with 23-bit encoder (8,388,608 pulses/rev) and 350 % peak torque; the G5 (R88M-K) is the previous generation with 20-bit encoder and 300 % peak torque. Pick 1S for new designs with NJ501 / NX102 / NX1P; pick G5 for compatibility with existing G5 systems.
Does the R88M-1M75030H-S2 have a battery?
No — the H suffix means 23-bit incremental encoder, which does not need a battery. If you need absolute position retention through power cycles, order the R88M-1M75030T-S2 (T suffix = 17-bit battery-free absolute encoder) or the R88M-1M75030T-BS2 (with brake). The 1S multi-turn absolute encoder uses an electronic counter that does not require a backup battery, unlike the G5 absolute encoder which did.
What controller pairs with the R88M-1M75030H-S2 over EtherCAT?
Any Sysmac controller: NJ501-1300, NJ501-1400, NJ501-1500, NX102-1000, NX102-1100, NX102-1200, or NX1P2-1040DT. Connect the R88D-1SN08H-ECT drive to the controller's EtherCAT port, scan the network in Sysmac Studio, and the axis configuration populates automatically. The 1S-series electronic data sheet (EDS) is included in Sysmac Studio 1.20 or later.
