R88M-K60020F-S2 - Omron Accurax G5 600 W AC servo motor

Documented AC servo-motor role for R88M-K60020F-S2, with source-backed evidence and explicit installation boundaries.

Documented function

Rebuilt from individual evidence

System position

Unknown: Evidence boundary

Omron lists R88M-K60020F-S2 as an Accurax G5 incremental AC servo motor rated at 600 W, 400 V, and 2000 r/min.

The motor variant is listed with a straight shaft with key and tap and without a brake.

Omron lists rated torque of 2.86 Nm and peak torque of 8.59 Nm for the exact 600 W variant.

The motor sits downstream of its servo drive and upstream of the machine axis or load.

The incremental encoder supplies rotor feedback to the servo control loop.

Unknown: The installed servo drive, feedback wiring, firmware, machine load, and site-specific compatibility are not established by the captured sources.

System role

This section explains what the product does and where it acts in the surrounding system.

Function: Drives a controlled machine axis with the documented servo torque and speed.
System position: Sits downstream of its servo drive and upstream of the machine axis or load.
Upstream / inputs: Receives electrical power and motion commands from the matched servo drive.
Downstream / outputs: Delivers rotary torque and incremental encoder feedback to the servo system.
Limitations: Unknown: The installed servo drive, feedback wiring, firmware, machine load, and site-specific compatibility are not established by the captured sources.
