324 Fault tracing
2340 Short circuit Short-circuit in motor
cable(s) or motor
Aux code 0x0080
indicates that the state
feedback from output
phases does not match
the control signals.
Check motor and motor cable for
cabling errors.
Check there are no power factor
correction capacitors or surge
absorbers in motor cable.
Cycle the power to the drive.
01 a short circuit in the
upper IGBT of the
U-phase
02 a short circuit in the
lower IGBT of the
U-phase
04 a short circuit in the
upper IGBT of the
V-phase
08 a short circuit in the
lower IGBT of the
V-phase
10 a short circuit in the
upper IGBT of the
W-phase
20 a short circuit in the
lower IGBT of the
W-phase
40 DC capacitor short
circuit
2381 IGBT overload Excessive IGBT junction
to case temperature.
This fault protects the
IGBT(s) and can be
activated by a short
circuit in the motor cable.
Check motor cable.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-
up.
Check motor power against drive
power.
2392 BU earth leakage Total earth leakage of
inverter modules is
excessive. Check there are no power factor
correction capacitors or surge
absorbers in motor cable.
Measure insulation resistances of
motor cables and motor.
