A5EB PU board powerfail
Cause
Communication errors
detected between the drive
control unit and the power unit.
Cooling fan feedback missing.
An auxiliary cooling fan
(connected to the fan
connectors on the control unit)
is stuck or disconnected.
Safe torque off function is
active, i.e. safety circuit
signal(s) connected to
connector XSTO is lost.
Problem with internal
temperature measurement of
the drive.
Power unit power supply
failure.
What to do
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).
Check the setting of parameter
HW options word 1, bit 14.
Check the auxiliary code to identify the
fan. Code 0 denotes main fan 1. Other
codes (format XYZ): "X" specifies state
code (1: ID run, 2: normal). "Y" specifies
the index of the inverter unit connected to
BCU (0...n, always 0 for ZCU control
units). "Z" specifies the index of the fan
(1: Main fan 1, 2: Main fan 2, 3: Main fan
3).
Check fan operation and connection.
Replace fan if faulty.
The auxiliary code identifies the fan (1:
Auxiliary fan 1, 2: Auxiliary fan 2).
Check auxiliary fan(s) and connection(s).
Replace faulty fan.
Make sure the front cover of the drive
module is in place and tightened. If the
commissioning of the drive requires that
the cover is off, this warning will be
generated even if the corresponding fault
is defeated. See fault 5081 Auxiliary fan
broken (page 494).
Check safety circuit connections. For
more information, see appropriate drive
hardware manual and description of
parameter 31.22 STO indication run/stop
(page 258).
Check the auxiliary code (format XXXY
YYZZ). "Y YY" specifies through which
BCU control unit channel the fault was
received ("0 00" with a ZCU control unit).
"ZZ" specifies the location (1: U-phase
IGBT, 2: V-phase IGBT, 3: W-phase
IGBT, 4: Power unit INT board, 5: Brake
chopper, 6: Air inlet, 7: Power supply
board, 8: du/dt filter, FAh: Air in temp).
