Fault tracing 599
71A3
Mechanical brake
opening failed
Programmable fault:
Mechanical brake control fault.
Activated eg. if brake
acknowledgement is not as
expected during brake
opening.
Check mechanical brake connection.
Check mechanical brake settings in
parameter group
.
Check that acknowledgement signal
matches actual status of brake.
71A5
Mechanical brake
opening not allowed
Programmable fault:
Open conditions of mechanical
brake cannot be fulfilled (for
example, brake has been
prevented from opening by
parameter
).
Check mechanical brake settings in
parameter group
(especially
).
Check that acknowledgement signal (if
used) matches actual status of brake.
In an encoderless application,
the brake is kept closed by a
brake close request (either
from parameter
or from an
FSO-xx safety functions
module) against a modulating
drive for longer than 5
seconds.
Check the source signal selected by
parameter
Check the safety circuits connected to
the FSO-xx safety functions module.
71B1
Motor fan
Programmable fault:
No feedback received from
external fan.
Check external fan (or other equipment
controlled) by the logic.
Check settings of parameters
…
7301
Motor speed feedback
Programmable fault:
No motor speed feedback
received.
See
(page
).
7310
Overspeed
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.
Check minimum/maximum speed
settings, parameters
Check adequacy of motor braking torque.
Check applicability of torque control.
Check need for brake chopper and
resistor(s).
Incorrect estimated speed.
Check the status of motor current
measurement.
Perform a
or
ID run.

7380
Encoder internal
Internal fault.
Contact your local ABB representative.
7381
Encoder
Programmable fault:
Encoder feedback fault.
See

73A0
Speed feedback

Speed feedback configuration
incorrect.
