This trip indicates that a power stage over-temperature has been detected. The sub-trip "xxyzz" indicates which thermistor is indicating the over-temperature. The
thermsitor numbering is different for a single module type drive (i.e. no parallel board fitted) and a multi-module type drive (i.e. parallel board fitted with one or more
power modules) as shown below:

Recommended actions:
Check enclosure / drive fans are still functioning correctly.
Force the heatsink fans to run at maximum speed.
Check enclosure ventilation paths.
Check enclosure door filters.
Increase ventilation.
Reduce duty cycle.
Decrease acceleration / deceleration rates.
Reduce motor loads.
Check the derating tables and confirm the drive is correctly sized for the application.
Use a drive with larger current / power rating.

Short description
This trip indicates that the instantaneous drive output current has exceeded the drive over current threshold.

0
00: Instantaneous over-current trip when the measured a.c. current exceeds
over current threshold.
The over current threshold is the maximum current the drive can measure and is defined by VM_DRIVE_CURRENT[MAX].
Recommended actions:
Acceleration / deceleration rate is too short.
If seen during auto-tune reduce the voltage boost.
Check for short circuit on the output cabling.
Check integrity of the motor insulation using a Megger.
Check feedback device wiring.
Check feedback drive mechanical coupling.
