Display: "Er 0E1"
1 Content: Intelligent Power Module (IPM) overcurrent
Diagnosis
Verify if there is short circuit
between UVW terminals, or
shorted to PG.
Verify motor wiring
Disconnect motor output cable.
Then, enable servo driver to
check for overcurrent
Verify if parameter exceeds
recommended range
Verify if command motion is too
acute
Display: "Er 0E2"
2 Content: Power output to motor shorted to ground
Diagnosis
Disconnect motor power cable
and check for short circuit
between driver UVW and PE
Connect motor power cable to
driver power output. Verify if
resistance value of UVW to PE is
in the range of MegaOhm (MΩ)
Display: "Er 0E4"
2 Content: Phase overcurrent
Diagnosis
Disconnect motor power cable
and check for short circuit
between driver UVW and PE
Connect motor power cable to
driver power output. Verify if
resistance value of UVW to PE is
equal and if there is short circuit
