Fault tracing 373
7085
Incompatible option
module
Option module not supported.
(For example, type Fxxx-xx-M
fieldbus adapter modules are
not supported.)
Check the auxiliary code. The code
specifies the interface to which the
unsupported module is connected:
1:
Fieldbus interface A,
2:
Fieldbus
interface B.
Replace the module with a supported
type.
7121
Motor stall
Motor is operating in stall
region because of e.g.
excessive load or insufficient
motor power.
Check motor load and drive ratings.
Check fault function parameters.
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
chopper and resistor.
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.
71A2
Mechanical brake
closing failed
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
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.
