IGBT short circuit

Was bedeutet F020 ?

This ATV310 fault indicates an internal power component short circuit, specifically within the IGBTs (Insulated Gate Bipolar Transistors) of the drive's inverter section. This critical hardware failure is typically detected at power-on and requires specialized repair.

1. 1

   Turn the ATV310 drive off and then back on again after waiting for at least 5 minutes to ensure a full reset.

2. 2

   Check the input power supply to the drive for stability and ensure correct voltage levels are present.

3. 3

   Visually inspect the drive for any obvious signs of internal power component damage (e.g., burn marks, bulges in capacitors), though access requires caution.

4. 4

   Contact local Schneider Electric representative for repair or replacement of the drive due to an IGBT short circuit.
