Key ratings and what they mean for fit
The R88D-KP08H-Z: Rated at 1.3 kVA power supply capacity and 4.1 A continuous output current, this servo driver is sized for a small-to-medium servo motor on a 200 V-class line. The 4.1 A figure is the continuous RMS current the drive can deliver to the motor — the number that governs whether it can hold torque on a constant-load axis like a conveyor or spindle. If your motor nameplate continuous current exceeds 4.1 A, this driver will thermally trip under sustained load.
