Supply to Gate Driver Not Enabled

What does F00026 mean?

The gate driver, which controls the inverter's power transistors (IGBTs), is not enabled. This critical internal fault prevents the inverter from generating output voltage and can be indicative of a hardware issue with the gate drive board or a synchronization problem within the safety state machines. This renders the drive inoperable.

Complete Troubleshooting Guide

1. 1

   Immediately power down the drive and isolate it from the mains supply.

2. 2

   Contact the Siemens Service Department for detailed diagnostics and potential hardware replacement, as this is usually an internal component failure.
