Checksum group error safe monitoring on at least one axis.
Confirmation and acceptance test required!
A checksum protects the relevant MD to parameterize the axis--specific
safety functionality. The alarm indicates that at least on one axis, at
least one of the axis--specific checksums no longer matches the saved
checksum, i.e. that a data item was illegally changed or is corrupt.
This alarm is displayed during the commissioning phase (SPL--commis-
sioning mode active) as global group alarm for the axis--specific check-
sum alarm 27132. This alarm reduction is parameterized in MD10094
$MN_SAFE_ALARM_SUPPRESS_LEVEL (100 position set).

Wait for Motor Module for at least one axis
Alarm when booting as long as the Motor Module of at least one axis is
still not ready for SI. When booting, communications to the Motor
Module have still not been established as the safety functions for at
least one axis are still not available.
The alarm display can be set in MD10094 $MN_SAFE_ALARM_SUP-
PRESS_LEVEL (MD < 3) in such a way that it can be individually dis-
played as to whether communications have already been established
for each axis.
The alarm is continuously active when booting if at least one drive does
not communicate. Otherwise, the alarm is only briefly present and is
then automatically cleared again.
Possible causes for the alarm being permanently present:
