36902 $MA_SAFE_IS_ROT_AX
MD number Rotary axis
Default: 0
Change becomes effective after POWER ON:
Data type: BOOLEAN
Meaning Data specifies whether the axis for safe operation is a rotary axis/spindle or linear axis.
= 0:
= 1:
The value set in this MD must be the same as the value set in MD: $MA_IS_ROT_AX. A
parameterization error is displayed if they are not identical.
Corresponds with ... MD 30300: $MA_IS_ROT_AX
36905 $MA_SAFE_MODULO_RANGE
MD number Modulo value for SN
Default: 0.0
Change becomes effective after POWER ON:
Data type: DOUBLE
Meaning Actual value range within which safe cams for rotary axes are calculated. The axis must
be a rotary axis ($MA_/$MD_SAFE_IS_ROT_AX = 1).

36910 $MA_SAFE_ENC_SEGMENT_NR
MD number Actual value assignment: Drive type
Default: 1
Change becomes effective after POWER ON:
Data type: BYTE
Meaning Number of the bus segment via which the encoder is addressed.
=1:
36911 $MA_SAFE_ENC_MODULE_NR
MD number Actual value assignment: Drive number/measuring circuit number
Default: 1
Change becomes effective after POWER ON:
Data type: BYTE
Meaning Module No. within a segment via which the SI encoder is addressed.
The logical drive number of the drive assigned to the axis via $MN_DRIVE_LOGIC_NR
must be entered here.
For standard applications with a 2-encoder system, the encoder for Safety Integrated is
connected to the second encoder connection (lower input) of the same drive module.
Special cases, errors Any actual value input in the 611 digital group can be used for the second encoder as the
measuring system on the NC side.

SINUMERIK 840D/SIMODRIVE 611 digital SINUMERIK Safety Integrated (FBSI) - Edition 11.03
Min. input value: 0
Protection level (R/W) 7/2
Applies from SW 3.4
Linear axis
Rotary axis/spindle
Min. input value: 0.0
Protection level (R/W) 7/2
Applies from SW 4.2
Modulo override after +/- 2048 revolutions
(i.e. after 737 280 degrees)
Modulo override after this setting (e.g. setting = 360
the actual value range is between 0 and 359.999 degrees, i.e. a
modulo override 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 during run-up.
The cam positions are also checked with respect to the parameterized actual value
range during run-up. An appropriate alarm is output if parameterization errors are
detected.
Actual value ranges set in $MA_SAFE_MODULO_RANGE and
$MA_MODULO_RANGE must be a multiple integer.
Min. input value: 0
Protection level (R/W) 0/0
Applies from SW 3.4
Drive bus of SIMODRIVE 611 digital (always used)
Min. input value: 1
Protection level (R/W) 7/2
Applies from SW 3.4
