Code P10-10104: I1 Overcurr UPos

Type: Resettable Fault Coast Y Y An instantaneous overcurrent (IOC) has occurred in the U, V, or W phase, positive or negative leg. • Reduce the mechanical load. • Check the motor and connections. • With motor disconnected, run the drive in open loop, in V/Hz mode and check for sufficient output phase-to-phase voltages. If an IOC occurs immediately after restarting the drive, check the appropriate current sensor. • Check the power and signal connections to the gate driver board for the phase that is identified, or replace it. The IGBT could also have failed open (and the opposite leg is receiving excess current).
