Overcurrent Protection During Constant Speed

What does E01. mean?

This fault occurs when a large current flows through the inverter while the motor operates at a constant speed, typically due to sudden load fluctuations or brake application. The inverter's protection circuit activates at approximately 200% of the rated output current, causing a trip to prevent damage to the inverter components.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Verify the motor and output wiring for any potential ground faults.

2. 4

   Increase the acceleration/deceleration time if the motor is rapidly accelerating or decelerating during operation.
