Cause
DC link voltage difference
detected by the branching unit.
High temperature difference
between the IGBTs of different
phases.
High temperature difference
between the semiconductors of
different phases.
IGBT temperature is
excessive.
Problem with internal
temperature measurement.
Power unit power supply
failure.
Communication errors
detected between the control
unit and the power unit.
Fault tracing 177
What to do
Check DC fuses.
Check converter module connections to
DC link.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against DC/DC
converter power.
Check the auxiliary code (format XXXY
YYZZ). "Y YY" specifies through which
BCU control unit channel the fault was
received. "ZZ" specifies the location
(1: U-phase, 2: V-phase, 3: W-phase,
4: INT board, 5: Brake chopper, 6: Air
inlet (sensor connected to INT board
X10), 7: PCB compartment fan or power
supply board, 8: du/dt filter or
temperature switch (XT) (sensor
connected to INT board X7), 9: Sensor
connected to INT board X6,
0FA: Ambient temperature).
Check the cabling.
Check cooling of power module(s).
Check the auxiliary code (format XXXY
YYZZ). "XXX" indicates the source of
difference (0: Single module, difference
between phase IGBTs, 1: parallel-
connected modules, minimum-maximum
difference between all IGBTs of all
modules). With parallel-connected
modules, "Y YY" specifies through which
BCU control unit channel the fault was
received. "ZZ" specifies the phase (0:
single module, 1: U-phase [parallel
connection], 2: W-phase [parallel
connection], 3: W-phase [parallel
connection]).
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against DC/DC
converter power.
Check the auxiliary code (format XXXY
YYZZ). "Y YY" specifies through which
BCU control unit channel the fault was
received. "ZZ" specifies the location (1:
U-phase, 2: V-phase, 3: W-phase, 4: INT
board, 5: Brake chopper, 6: Air inlet, 7:
Power supply board, 8: du/dt filter).
Contact your local ABB representative.
Check the connections between the
control unit and the power unit.
