Cause : An auxiliary cooling fan (connected to the fan connectors on the control unit) is stuck or disconnected.
1. Check the auxiliary code.
2. Check auxiliary fan(s) and connection(s).
3. Replace fan if faulty. Make sure the front cover of the drive is in place and tightened.
4. If the commissioning of the drive requires the cover is off, activate parameter
31.36 - Aux fan fault bybass within 2 min from control unit reboot to temporarily suppress the fault.
5. Reboot the control unit (using parameter 96.08 Control board boot) or by cycling power.
