Possible causes for the alarm being permanently present:
-- The safety motion monitoring functions are only activated in
MD36901 $MA_SAFE_FUNCTION_ENABLE, however, not in the
corresponding parameter of the associated drive (p9501).
-- The assignment axis --> drive via MD36906
$MA_SAFE_CRTLOUT_MODULE_NR, MD10393
$MN_SAFE_DRIVE_LOGIC_ADDRESS or p0978 is incorrect.
-- PROFIBUS connector fallen out.
The alarm is no longer displayed when the alarm cause has been
removed. No other operator actions are required.
