: Intelligent Power Module (IPM) overcurrent
Cause
Diagnosis
Solution
Driver power output
short circuit
Verify if there is short circuit
between UVW terminals, or
shorted to PG.
1. Make sure there is no circuit.
2. Make sure motor is not
damaged
Motor wiring error
Verify motor wiring
Reconnect motor wiring
IGBT module short
circuit
Disconnect motor output cable.
Then, enable servo driver to
check for overcurrent
Replace driver

Verify if parameter exceeds
recommended range
Set parameter within
recommended range.
Control command
anomaly
Verify if command motion is too
acute
Modify control command;
use filter

: Power output to motor shorted to ground
Cause
Diagnosis
Solution
Driver U, V, W terminals
shorted to ground
Disconnect motor power cable
and check for short circuit
between driver UVW and PE
1. Reconnect wiring.
2. Change motor power cable.
Motor shorted to ground
Connect motor power cable to
driver power output. Verify if
resistance value of UVW to PE is
in the range of MegaOhm (MΩ)
Replace motor

Disconnect motor power cable
and check for short circuit
between driver UVW and PE
1. Reconnect wiring.
2. Change motor power cable.
Motor shorted to ground
Connect motor power cable to
driver power output. Verify if
resistance value of UVW to PE is
equal and if there is short circuit
Replace motor
