AL. 033.1 Main circuit voltage error (Overvoltage) fault in Mitsubishi MELSERVO MR-JET Servo Drive
Cause: Regenerative resistor settings incorrect or not connected.
Remedy:
- Check [Pr. PA02] and wiring.
- Measure resistance of built-in resistor.
Cause: Regeneration capacity insufficient.
Remedy:
- Use a regenerative option with larger capacity.
- Increase deceleration time constant.
Cause: Power supply voltage too high.
Remedy:
- Check input voltage (Max 264V for 200V class).
