SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 05.2008 Edition
$MA_SAFE_MODULO_RANGE
Modulo value, safe cams
Min. input limit: 0.0
Protection level: 7/2
Actual value range within which safe cams for rotary axes are calculated. The axis must be
a rotary axis ($MA_SAFE_IS_ROT_AX = 1).
0:
Modulo correction after +/– 2048 revolutions (i.e. after 737 280 degrees)
> 0 and multiples of 360 Degrees:
Modulo correction after this value e.g. value = 360 degrees –> the actual value range is
between 0 and 359.999 degrees, i.e. a modulo correction is carried out after every revolu-
tion.
– If the value set in this data is not 0 or a multiple of 360 degrees, then an appropriate
alarm is output when the system boots.
– The cam positions are also checked with respect to the parameterized actual value
when the system boots. An appropriate alarm is output if parameterization errors are
detected.
– Actual value ranges set in $MA_SAFE_MODULO_RANGE and $MA_MO-
DULO_RANGE must be a multiple integer.
MD 30330: $MA_MODULO_RANGE
MD 36935: $MA_SAFE_CAM_POS_PLUS[n]
MD 36937: $MA_SAFE_CAM_POS_MINUS[n]
/FBSI/ see Chapter 6.8: "Safe software cams, safe cam track (SN)"
$MA_SAFE_CTRLOUT_MODULE_NR
SI drive assignment
Min. input limit: 1
Protection level: 7/2
Index in the data array $MN_SAFE_DRIVE_LOGIC_ADDRESS to assign the drive for SI
motion monitoring functions.
The same drive must be assigned that was also selected using CTRLOUT_MODULE_NR
and DRIVE_LOGIC_ADDRESS.
