Cause
Communication between
I/O module and drive is not
working properly.
Fieldbus option module not
supported.
Overvoltage detected in AI.
AI is changed to voltage
mode from mA mode. AI will
return automatically back to
mA mode when the AI sig-
nal level is within accept-
able limits.
Mechanical brake control
fault. Activated e.g., if brake
acknowledgment is not as
expected during brake clos-
ing.
Open conditions of mechan-
ical brake cannot be ful-
filled.
Excitation current feedback
low or missing
Motor is operating in stall
region.
Motor current is too high.
Brake resistor broken or not
connected.
What to do
Check the I/O module installation.
Replace the module with a supported
type.
Check AI signal levels.
Check mechanical brake connection.
Check mechanical brake settings in
parameter group 44 Mechanical brake
control.
Check that the acknowledgment sig-
nal matches the actual status of the
brake.
Check mechanical brake settings in
parameter group 44 Mechanical brake
control.
Check that the acknowledgment sig-
nal (if used) matches the actual status
of the brake.
Contact your local ABB representat-
ive.
Check motor load, drive ratings and
fault function parameters.
Check for overloaded motor
Adjust the parameters used for the
motor overload function.
(35.51...35.53, 35.55, 35.56)
Check connections and brake resistor
dimensioning.
