The troubleshooting guide says: Instantaneous overcurrent. The motor current being drawn from the
drive is too high.

To clear the DESAT Over I fault, treat the alarm the same as an OVERCURRENT alarm. Check the motor loading, motor acceleration, short circuit in the motor windings, or possible grounding of one of the motor leads.
