$MA_SAFE_ADD_FUNCTION_MASK
Enables additional functions for Safety Integrated
Min. input limit: 0H
Bit 0:
On the NCK side, for STOP B and C, braking is not initiated by entering "Speed setpoint 0".
Braking is realized on the drive side, based on the OFF3 ramp.
$MA_SAFE_MODULO_RANGE
Modulo value Safe Cams
Min. input limit: 0.0
Actual value range within which Safe Cams for rotary axes are calculated. The axis must be
a rotary axis (MD36902 $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 revolution.
● 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 MD36905 $MA_SAFE_MODULO_RANGE and MD30330
$MA_MODULO_RANGE must be multiple integers.
MD30330 $MA_MODULO_RANGE
MD36935 $MA_SAFE_CAM_POS_PLUS[n]
MD36937 $MA_SAFE_CAM_POS_MINUS[n]
/FBSIsl/ see Chapter "Safety software cams and safety cam track (SN) (Page 157)"
$MA_SAFE_CTRLOUT_MODULE_NR
SI drive assignment
Min. input limit: 0
Assignment of the drive for SI Motion monitoring functions
The entry refers to data array MD10393 $MN_SAFE_DRIVE_LOGIC_ADDRESS.
The same drive must be assigned, that was also selected using MD30110
$MA_CTRLOUT_MODULE_NR and MD13050 $MN_DRIVE_LOGIC_ADDRESS.
