$MA_SAFE_FUNCTION_ENABLE
The functions for safe operation can be enabled for one axis/spindle using this machine
data.
It is only possible to enable - on an axis-specific basis - as many axes/spindles for safe
operation as have been enabled by the global option.
The more partial functions that are set then the more computing time the safe functions
require.
Bit 0: enable safely reduced speed, Safe Operating Stop
Bit 1: enable safe limit switch
Bit 2: reserved for functions with absolute reference (such as SE/SN)
Bit 3: enable actual value synchronization, 2-encoder system
Bit 4: enable external ESR activation (STOP E)
Bit 5: enable SG correction
Bit 6: enable the external stop requests / external STOPs
Bit 7: enable cam synchronization
Bit 8: enable Safe Cams, pair 1, cam+
Bit 9: enable Safe Cams, pair 1, cam-
Bit 10: enable Safe Cams, pair 2, cam+
Bit 11: enable Safe Cams, pair 2, cam-
Bit 12: enable Safe Cams, pair 3, cam+
Bit 13: enable Safe Cams, pair 3, cam-
Bit 14: enable Safe Cams, pair 4, cam+
Bit 15: enable Safe Cams, pair 4, cam-
Bit 16: enable synchronization, hysteresis and filtering "n<n
Bit 23: enable deactivation of the SBH/SG monitoring during an external STOP A
● If bit 1 or a higher bit is set, then bit 0 must also be set since the control system switches
to a Safe Operating Stop in response to STOP C, D or E (a parameterizing alarm 27033
is displayed if an error is detected).
● If an insufficient number of axes/spindles have been enabled for safe operation using
the global option, then this data may be overwritten with the value 0000 when booting.

$MA_SAFE_IS_ROT_AX
Rotary axis
Min. input limit: -
This data specifies whether the axis for safe operation is a rotary axis/spindle or linear axis.
= 0: Linear axis
= 1: Rotary axis/spindle
The value in this MD must be the same as in MD30300 $MA_IS_ROT_AX. If they are not
identical a parameterizing error is displayed.
