Fault
Cause
Remedy
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.
F7093: Drive: Test signal
error
Reaction: OFF3
Acknowledgement:
IMMEDIATELY
The limit rotation of the motor (p29027) is
inappropriate.
Modify the value of parameter p29027.
F7220: Drive: Master control
by PLC missing
Reaction: OFF1
Acknowledgement:
IMMEDIATELY
The "master control by PLC" signal was
missing in operation.
•
Input for "master control by PLC" is
incorrect.
•
The higher-level control has withdrawn
the "master control by PLC" signal.
•
Data transfer via the fieldbus (mas-
ter/drive) was interrupted.
•
Check the input for "master control by
PLC".
•
Check the "master control by PLC" signal
and, if required, switch in.
•
Check the data transfer via the fieldbus
(master/drive).
F7403: Lower DC link voltage
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 voltage
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
threshold.
•
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 contactor
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.
