The Omron R88DKN01HECT is a 100 W servo drive from the Accurax G5 series, rated at 1.2 A continuous output with an AC input range of 170 to 264 V. It's sized for the companion R88M-K05030(H/T) or R88M-K10030(H/T) motors — that pairing defines the torque-speed curve. Operating ambient is 0 to 55 °C, so panel ventilation matters if it's boxed in with other heat sources.
The drive accepts single-phase AC input across the 170–264 V range — typical for a 100 W class machine-feed axis or a small indexing table. The 1.2 A rating is the continuous output to the motor; peak torque delivery depends on the specific motor in the pair. Panel mount, not DIN rail, so factor in the panel cutout and heatsink clearance. The 55 °C ceiling is the operating ambient at the drive inlet — derate or add forced air if the cabinet runs hotter.
