598 Fault tracing
7181
Brake resistor
Brake resistor broken or not
connected.
Check that a brake resistor has been
connected.
Check the condition of the brake resistor.
Check the dimensioning of the brake
resistor.
7183
BR excess
temperature
Brake resistor temperature has
exceeded fault limit defined by
parameter
.
Stop drive. Let resistor cool down.
Check resistor overload protection
function settings (parameter group
).
Check fault limit setting, parameter
Check that braking cycle meets allowed
limits.
7184
Brake resistor wiring
Brake resistor short circuit or
brake chopper control fault.
Check brake chopper and brake resistor
connection.
Ensure brake resistor is not damaged.
After correcting the cause of the fault,
reboot the control unit (using parameter
) or by cycling
power.
7191
BC short circuit
Short circuit in brake chopper
IGBT.
Ensure brake resistor is connected and
not damaged.
Check the electrical specifications of the
brake resistor against the
Hardware
manual
.
Replace brake chopper (if replaceable).
After correcting the cause of the fault,
reboot the control unit (using parameter
) or by cycling
power.
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.
