Fault
Cause
Remedy
F1912: Clock cycle synchro-
nous operation sign-of-life
failure
Reaction: OFF1
Acknowledgement:
IMMEDIATELY
The maximum permissible number of
errors in the controller sign-of-life (clock
synchronous operation) has been exceed-
ed in cyclic operation.
• Physically check the bus (cables, connect-
ors, terminating resistor, shielding, etc.).
• Correct the interconnection of the controller
sign-of-life.
• Check whether the controller correctly
sends the sign-of-life.
• Check the permissible telegram failure rate.
• Check the bus and controller for utilization
level (e.g. bus cycle time was set too
short).
F7011: Motor overtempera-
ture
Reaction: OFF2
Acknowledgement:
IMMEDIATELY
•
Motor overloaded
• Motor surrounding air temperature too
high
• Wire breakage or sensor not connect-
ed
• Motor temperature model incorrectly
parameterized
•
Reduce the motor load.
• Check the surrounding air temperature and
the motor ventilation.
• Check the wiring and the connection.
• Check the motor temperature model pa-
rameters.
F7085: Open-loop/closed-
loop control parameters
changed
Reaction: NONE
Acknowledgement:
IMMEDIATELY
Open-loop/closed-loop control parameters
have had to be changed for the following
reasons:
• As a result of other parameters, they
have exceeded the dynamic limits.
• They cannot be used due to the fact
that the hardware detected not having
certain features.
It is not necessary to change the parameters
as they have already been correctly limited.
F7403: Lower DC link volt-
age threshold reached
Reaction: OFF1
Acknowledgement:
IMMEDIATELY
The DC link voltage monitoring is active
and the lower DC link voltage threshold
was reached in the "Operation" state.
• Check the line supply voltage.
• Check the infeed.
• Reduce the lower DC link threshold.
• Switch out (disable) the DC link voltage
monitoring.
F7404: Upper DC link volt-
age threshold reached
Reaction: OFF2
Acknowledgement:
IMMEDIATELY
The DC link voltage monitoring is active
and the upper DC link voltage threshold
was reached in the "Operation" state.
• Check the line supply voltage.
• Check the infeed module or the brake
module.
• Increase the upper DC link voltage thresh-
old.
• Switch out (disable) the DC link voltage
monitoring.
F7410: Current controller
output limited
Reaction: OFF2
Acknowledgement:
IMMEDIATELY
The condition "I_act = 0 and Uq_set_1
longer than 16 ms at its limit" is present
and can be caused by the following:
• Motor not connected or motor contac-
tor open.
• No DC link voltage present.
•
Motor Module defective.
• Connect the motor or check the motor
contactor.
• Check the DC link voltage.
• Check the Motor Module.
F7411: Drive: Flux controller
output limited
Reaction: OFF2
Acknowledgement:
IMMEDIATELY
The specified flux setpoint cannot be
reached although 90% of the maximum
current has been specified.
• Incorrect motor data.
• Motor data and motor configuration do
not match.
• The current limit has been set too low
for the motor.
• Induction motor (encoderless, open-
loop controlled) in I
2
t limiting.
• Correct the motor data.
• Check the motor configuration.
• Reduce the induction motor load.
