Cause : Overcurrent fault -

Motor power (P0307) does not correspond to the inverter power (r0206).
Motor lead short circuit
Earth faults
r0949 = 0: Hardware reported
r0949 = 1: Software reported
r0949 = 22: Hardware reported

Check the following:


Motor power (P0307) must correspond to in- verter power (r0206).
Cable length limits must not be exceeded.
Motor cable and motor must have no short- circuits or earth faults.
Motor parameters must match the motor in use.
Value of stator resistance (P0350) must be correct.
Motor must not be obstructed or overloaded.
Increase ramp-up time (P1120)
Reduce starting boost level (P1312)
