2381 IGBT overload
2392 BU earth leakage
Cause
Load unbalance typically
due to earth fault in motor
or motor cable.
Short-circuit in motor
cable(s) or motor.
Short circuit in the upper
transistor of the U-phase.
Short circuit in the lower
transistor of the U-phase.
Short circuit in the upper
transistor of the V-phase.
Short circuit in the lower
transistor of the V-phase.
Short circuit in the upper
transistor of the W-phase.
Short circuit in the lower
transistor of the W-phase.
DC capacitor short circuit.
State feedback from out-
put phases does not
match control signals.
For frames R6 and R7.
Excessive IGBT junction to
case temperature.
Total earth leakage of in-
verter modules is excess-
ive.
Diagnostics 155
What to do
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.
Check motor and motor cable for
cabling errors. Check there are no
power factor correction capacitors
or surge absorbers in motor cable.
For frames R6 to R8, check the aux-
iliary code.
Check motor cable.
Check there are no power factor
correction capacitors or surge ab-
sorbers in motor cable.
Measure insulation resistances of
motor cables and motor.
