Cause: Overcurrent condition during acceleration comes when drive detected a large output current exceeding protection limits, and it tripped instantly to protect itself.

e0c1 mitsubishi indicates an overcurrent trip during acceleration. This means that the inverter detected an output current exceeding its rated capacity while the motor was accelerating.

Troubleshooting Steps:

Follow these steps to correct e0c1 mitsubishi:

• Check for Output Short Circuit: Turn off the power to the inverter and disconnect the motor cables (U, V, W).
• Verify Parameter Settings: Check the inverter's acceleration time parameter and increase it if it is set too short.
• Inspect Motor and Load: Ensure the motor is not mechanically overloaded. Check for any obstructions or excessive friction in the driven equipment.
• Motor or inverter capacity mismatch: Ensure the inverter capacity matches the motor capacity.
