Overload Protection

What does E05. mean?

This fault indicates that the motor is operating under an excessive load, causing the inverter's output current or its electronic thermal protection function to trip. It can also be triggered if the electronic thermal level (b012/b212) is set incorrectly, failing to adequately protect against motor burnout.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   If using multiple motors, ensure individual thermal relays are installed and configured correctly.

2. 4

   Increase the acceleration time (F002/F202) if insufficient acceleration torque is causing the overload trip.
