Code
(hex)
Check there are no power factor
correction capacitors or surge ab-
sorbers in motor cable and there is
no earth fault in motor or motor
cables.
Load unbalance typically
due to earth fault in motor
or motor cable.
Earth leakage2330
Check motor and motor cable for
cabling errors. Check there are no
power factor correction capacitors
or surge absorbers in motor cable.
Short-circuit in motor
cable(s) or motor.
Short circuit2340
Short circuit in the upper
transistor of the U-phase.
0001
For frames R6 to R8, check the aux-
iliary code.
Short circuit in the lower
transistor of the U-phase.
0002
Short circuit in the upper
transistor of the V-phase.
0004
Short circuit in the lower
transistor of the V-phase.
0008
Short circuit in the upper
transistor of the W-phase.
0010
Short circuit in the lower
transistor of the W-phase.
0020
DC capacitor short circuit.0040
State feedback from out-
put phases does not
match control signals.
0080
For frames R6 and R7.
Check motor cable.Excessive IGBT junction to
case temperature.
IGBT overload2381
Check there are no power factor
correction capacitors or surge ab-
sorbers in motor cable.
Measure insulation resistances of
motor cables and motor.
