Integration and wiring context
As a Mitsubishi MR-J series servo drive, the MR-J40A-S31 expects a 200 VAC or 400 VAC three-phase supply depending on the specific variant — the exact voltage class is not confirmed here. The drive connects to a compatible servo motor via a dedicated power and encoder cable; Mitsubishi typically uses a 17-pin or 20-pin connector for the encoder feedback, and a separate terminal block for main power and regenerative resistor. No wiring diagram is provided in this listing, so verify the connector pinout against the official manual before terminating cables.
