Functional Safety for Frequency Converters, Upgradable (+BEF2)
Cause
The safety parameters are invalid or not
present in the device.
Mismatch of safety destination address.
Timeout in communication to safe
module. F_WD_Time or F_WD_Time_2
elapsed.
Advanced safety unit is in a software up-
date state.
Factory reset action triggered by the user.
Safety parametrization action triggered by
user.
Due to the configuration, IO acknowledge
is needed.
Due to the configuration, STO acknowl-
edge is needed.
Check of the safety parameters failed.
The value of a parameter is out of the al-
lowed range. The variable ID is provided
as detail.
Solution
Check the safety configuration in My-
Drive® Insight. Make sure that all configu-
ration steps are successfully verified and
validated.
Recommissioning of the safe module is re-
quired.
Make sure that the addresses on the PLC
and the drive match.
Increase the F_WD_Time or
F_WD_Time_2.
The device stays in a safe state until the
software update is successfully finished.
After the factory reset has been per-
formed, the safety configuration needs to
be recreated.
The safety configuration has been
changed. Ensure that the configuration is
correct before continuing.
Major safety configuration changes may
require a system restart.
If enabled, the safety function may require
an acknowledgment to continue opera-
tion after a signal failure has been cleared.
If enabled, the safety function may re-
quire an acknowledgment to continue
operation after a STO condition has been
cleared.
Ensure that the safety configuration is
valid. The possible errors may be related
to:
• input signal mapping
• output signal mapping
• timing parameters
Make sure that the value of the given vari-
able is set in the allowed range.
