SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 05.2008 Edition
Axis %1 safety–related monitoring functions.
and acceptance test required!
%1 = axis number
The relevant MDs $MN_SAFE_..., $MN_PROFISAFE_..., $MA_SAFE
... are protected by a checksum. The alarm indicates that the current
checksum is no longer the same as the reference checksum that has
been saved, i.e. this means that an MD value has either been changed
illegally or data is corrupted.
Mode group not ready
Channel not ready
NC start inhibit in this channel

NC stop for alarm
The actions that are necessary depend on which checksum entry in
SAFE_ACT_CHECKSUM deviates from the expected checksum in
SAFE_DES_CHECKSUM:
– SAFE_ACT_CHECKSUM[0]
Check MDs. Have the checksum re–calculated. Re–accept the
safety functions (motion monitoring functions, SPL, safety commu-
nications).
– SAFE_ACT_CHECKSUM[1]
Check the hardware related parameterization. Have the checksum
re–calculated. Check the safety functions (motion monitoring func-
tions).
– SAFE_ACT_CHECKSUM[2]
Check the PROFIsafe parameterization on the S7 side. Have the
checksum re–calculated. Re–accept the safety functions (PROFI-
safe I/O).
Power–down the control and power–up again
Axis %1 parameterization of the MD %2[%3] not valid
%1 = axis number
%2 = machine data identifier
%3 = machine data index
The parameterization of machine data %2 is incorrect. An additional
indication is the field index of the machine data. If the machine data is a
single machine data, a zero is specified as array index. This alarm oc-
curs in the following contexts:
– The conversion of the specified MD into the internal computation
format resulted in an overflow.
