The R88MK3K010FS2: Rated torque is 28.7 Nm at 1000 min⁻¹ output speed — that's the continuous stall torque the motor can deliver without overheating, which sets the sizing floor for the load it can accelerate and hold. The 11.3 A rated current is the continuous RMS current the drive must supply; undersize the drive's continuous current rating below this and you'll trip on I²t overload during normal cycling. The motor will run on a 400 V-class drive, but verify the drive's DC bus voltage matches the motor's insulation rating at the upper end. The G5 series is Omron's compact, high-torque-density servo platform — this motor is sized for medium-load rotary axes on packaging, assembly, or material-handling lines where the 28.7 Nm and 1000 min⁻¹ match a direct-drive or low-ratio application.
Frame dimensions are 210 mm width × 176 mm height × 176 mm length. That's a square-profile motor with a long body — check the available swing radius in your cabinet or on the machine frame before committing the mounting pattern.
