510 Fault tracing
A799
Ext I/O comm loss
Programmable warning:
The I/O extension module
types specified by parameters
do not match the detected
configuration.
Check the auxiliary code (format
XXYY YYYY). “XX” specifies the number
of the I/O extension module (
01:
parameter group
02:
,
03:
“YY YYYY” indicates the problem (see
actions for each code below).
00 0001 Communication with module
failed.
Check that the module is properly seated
in its slot.
Check that the module and the slot
connector is not damaged.
Try installing the module into another
slot.
00 0002 Module not found.
Check the type and location settings of
the modules (parameters
).
Check that the module is properly seated
in its slot.
Check that the module and the slot
connector is not damaged.
Try installing the module into another
slot.
00 0003 Configuration of module failed.
00 0004 Configuration of module failed.
A79B
BC short circuit
Short circuit in brake chopper
IGBT
Replace brake chopper if external. Drives
with internal choppers will need to be
returned to ABB.
Ensure brake resistor is connected and
not damaged.
A79C
BC IGBT excess
temperature
Brake chopper IGBT
temperature has exceeded
internal warning limit.
Let chopper cool down.
Check for excessive ambient
temperature.
Check for cooling fan failure.
Check for obstructions in the air flow.
Check the dimensioning and cooling of
the cabinet.
Check resistor overload protection
function settings (parameters
).
Check minimum allowed resistor value
for the chopper being used.
Check that braking cycle meets allowed
limits.
Check that drive supply AC voltage is not
excessive.
A7A1
Mechanical brake
closing failed
Programmable warning:
Status of mechanical brake
acknowledgement is not as
expected during brake close.
Check mechanical brake connection.
Check mechanical brake settings in
parameter group
.
Check that acknowledgement signal
matches actual status of brake.
