Cause
No feedback received from
external fan.
No motor speed feedback
received.
90.45
Motor is turning faster than
highest allowed speed due to
incorrectly set
minimum/maximum speed,
insufficient braking torque or
changes in load when using
torque reference.
The supply unit has tripped on
a fault.
Internal fault.
Encoder 1 feedback fault.
Encoder 2 feedback fault.
Speed feedback configuration
incorrect.
Fault tracing 369
What to do
Check external fan (or other equipment
controlled) by the logic.
Check settings of parameters
35.100...35.106.
Check the event log for an auxiliary code.
See appropriate actions for each code at
A7B0 Motor speed feedback
Check minimum/maximum speed
settings, parameters 30.11 Minimum
speed and 30.12 Maximum
Check adequacy of motor braking torque.
Check applicability of torque control.
Check need for brake chopper and
resistor(s).
If using a control panel or the Drive
composer tool, connect to the supply unit
to read the fault code. Refer to the
firmware manual of the supply unit for
instructions related to the code.
Contact your local ABB representative.
If fault appears during first start-up before
encoder feedback is used:
- Check cable between encoder and
encoder interface module (FEN-xx) and
order of connector signal wires at both
ends of cable.
If fault appears after encoder feedback
has already been used or during drive :
- Check that encoder connection wiring
or encoder is not damaged.
- Check that encoder interface module
(FEN-xx) connection or module is not
damaged.
- Check earthings (when disturbances
are detected in communication between
encoder interface module and encoder).
For more information on encoders, see
parameter groups 90 Feedback
selection, 91 Encoder module
92 Encoder 1 configuration
Encoder 2 configuration.
Check the event log for an auxiliary code.
See appropriate actions for each code at
A7E1 Encoder 1 or A7E2 Encoder 2
(page 359).
Check the feedback source selection
parameters in group 90 Feedback
selection. In case the source is an
encoder interface, check parameter
settings in groups 91 Encoder module
settings, 92 Encoder 1 configuration
93 Encoder 2 configuration.
Check the event log for an auxiliary code.
See appropriate actions for each code
