Use the built-in TEST function to confirm basic motor rotation when command pulses are absent. If the motor does not energize, verify AC power and the H.O input state before replacing hardware.

Inspect pulse wiring, grounding and motor current adjustment. Keep command pairs separated from power and motor conductors to reduce noise-related positioning errors.

Mount the driver with its base in close contact with a metal surface and provide cabinet ventilation. Isolate AC power before changing terminal wiring.

Retain the original pulse mode, current setting and compatible motor connection. Confirm the complete KR-505M order identity before a like-for-like changeover.
