Fault tracing 503
A4B1
Excess temperature
difference
High temperature difference
between the IGBTs of different
phases.
Check the motor cabling.
Check cooling of drive 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,
2:
parallel-connected modules,
minimum-maximum difference between
auxiliary power supply boards). With
parallel-connected modules, “Y YY”
specifies through which BCU control unit
channel the highest temperature was
measured. “ZZ” specifies the phase (
0:
single module,
1:
U-phase [parallel
connection],
2:
V-phase [parallel
connection],
3:
W-phase [parallel
connection]).
A4B2
PCB space cooling
Temperature difference
between ambient and drive
module PCB space is
excessive.
Check the cooling fan inside the PCB
space.
With parallel-connected modules, check
the auxiliary code (format XXXY YYZZ).
“Y YY” specifies through which BCU
control unit channel the fault was
received.
A4F6
IGBT temperature
Drive IGBT temperature is
excessive.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive power.
A580
PU communication
Communication errors
detected between the drive
control unit and the power unit.
Check the connections between the drive
control unit and the power unit.
Check the auxiliary code (format XXXY
YYZZ). With parallel-connected modules,
“Y YY” specifies the affected BCU control
unit channel (
0:
broadcast). “ZZ”
specifies the error source
(
8:
Transmission errors in PSL link [see
“XXX”],
9:
Transmitter FIFO warning limit
hit). “XXX” specifies the transmission
error direction and detailed warning code
(
0:
Rx/communication error,
1:
Tx/Reed-
Solomon symbol error,
2:
Tx/no
synchronization error,
3:
Tx/Reed-
Solomon decoder failures,
4:
Tx/Manchester coding errors).
Read the PSL2 data log. In Drive
composer pro, check the time stamp of
the A580 fault. Load the log with the
same date and time. When the file
opens, click “Show fault log”.
Check the power unit hardware.
