532 Fault tracing
7192
BC IGBT excess
temperature
Brake chopper IGBT
temperature has exceeded
internal fault limit.
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 (parameter group
Check that braking cycle meets allowed
limits.
Check that drive supply AC voltage is not
excessive.
71A2
Mechanical brake
closing failed
Programmable fault:
Mechanical brake control fault.
Activated eg. if brake
acknowledgement is not as
expected during brake closing.
Check mechanical brake connection.
Check mechanical brake settings in
parameter group
.
Check that acknowledgement signal
matches actual status of brake.
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.
