What to do
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.
Check the resistor data settings (parameters
43.08...43.10).
Check the event log for an auxiliary code (format XXYY
ZZZZ). "XX" specifies the number of the encoder interface
module (01: 91.11/91.12, 02: 91.13/91.14), "YY" specifies
the encoder (01: 92 Encoder 1 configuration, 02: 93
Encoder 2 configuration). "ZZZZ" indicates the problem
(see actions for each code below).
Check module location (91.12 or 91.14).
Check the module type (91.11 or 91.13) against status
(91.02 or 91.03).
Contact your local ABB representative.
Contact your local ABB representative.
Check module type (91.11 or 91.13) against encoder type
(92.01 or 93.01).
Check module location (91.12 or 91.14).
Use parameter 91.10 Encoder parameter refresh) to
validate any changes in the settings.
Replace brake chopper if external. Drives with internal
choppers will need to be returned to ABB.
Ensure brake resistor is connected and not damaged.
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 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.
Check mechanical brake connection.
Check mechanical brake settings in parameter group 44
Mechanical brake control.
Check that acknowledgement signal matches actual
status of brake.
Check mechanical brake connection.
Check mechanical brake settings in parameter group 44
Mechanical brake control.
Check that acknowledgement signal matches actual
status of brake.
