Supply to Gate Driver Not Enabled

Hva betyr F00026 ?

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.

• Internal control board failure preventing the gate driver supply from being activated.
• Low or missing auxiliary power supply (e.g., 24VDC or 15VDC) to the gate driver circuits.
• Detection of an overtemperature condition in the power stack, causing gate driver suppression.
• Fault in the gate driver circuit itself (e.g., component failure on the gate driver board).
• Incorrect or damaged fiber optic link (if used) between control board and gate driver.

1. 1

   Verify the presence and stability of auxiliary control voltages (e.g., 24VDC, 15VDC) on the control board or gate driver power supply points.

2. 2

   Check the drive's internal temperature sensors (e.g., heatsink temperature) via parameter readouts to ensure no overtemperature condition is present.

3. 3

   Inspect the connections between the main control board and the gate driver board(s) for tightness and correct seating.

4. 4

   If applicable, inspect the fiber optic cables connecting the control unit to the power module for damage or correct insertion.

5. 5

   Perform a full power cycle of the drive (e.g., disconnect mains for 1 minute) to reset internal states.
