Table 13-1 Warning Messages (Alphabetical by Keypad Text)
Warning Fault # Cause What to do
BR excess
temperature
A793 Brake resistor temperature
has exceeded warning
limit dened by parameter
43.12 Brake resistor
warning limit.
Stop drive. Let resistor cool down.
Check resistor overload protection function settings
(parameter group 43 Brake chopper).
Check warning limit setting, parameter 43.12 Brake
resistor warning limit.
Check that the resistor has been dimensioned correctly.
Check that braking cycle meets allowed limits.
BR data A794 Brake resistor data has
not been given.
Check the resistor data settings (parameters
43.08…43.10).
Speed feedback
conguration
A797 Speed feedback
conguration has
changed.
Check the event log for an auxiliary code (format XXYY
ZZZZ). “XX” species the number of the encoder interface
module (01: 91.11/91.12, 02: 91.13/91.14), “YY” species
the encoder (01: 92 Encoder 1 conguration, 02: 93
Encoder 2 conguration). “ZZZZ” indicates the problem
(see actions for each code below).
0001 Adapter not found in
specied slot.
Check module location (91.12 or 91.14).
0002 Detected type of interface
module does not match
parameter setting.
Check the module type (91.11 or 91.13) against status
(91.02 or 91.03).
0003 Logic version too old. Contact your local ABB representative.
0004 Software version too old. Contact your local ABB representative.
0006 Encoder type incompatible
with interface module
type.
Check module type (91.11 or 91.13) against encoder type
(92.01 or 93.01).
0007 Adapter not congured. Check module location (91.12 or 91.14).
0008 Speed feedback
conguration has
changed.
Use parameter 91.10 Encoder parameter refresh) to
validate any changes in the settings.
BC short circuit A79B 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.
BC IGBT excess
temperature
A79C 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 ow.
Check the dimensioning and cooling of the cabinet.
Check resistor overload protection function settings
(parameters 43.06…43.10).
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.
Mechanical brake
closing failed
Programmable warning:
44.17 Brake fault function
A7A1 Status of mechanical
brake acknowledgement
is not as expected during
brake close.
Check mechanical brake connection.
Check mechanical brake settings in parameter group 44
Mechanical brake control.
Check that acknowledgement signal matches actual
status of brake.
Mechanical brake
opening failed
Programmable warning:
44.17 Brake fault function
A7A2 Status of mechanical
brake acknowledgement
is not as expected during
brake open.
Check mechanical brake connection.
Check mechanical brake settings in parameter group 44
Mechanical brake control.
Check that acknowledgement signal matches actual
status of brake.
