$MA_SAFE_POS_LIMIT_MINUS[0...1]
This MD specifies the lower limit value for safe end positions 1 and 2.
When SE1 or SE2 is selected and the actual position is less than this limit value, then the
control system outputs Alarm 27012 with the stop response configured in MD36962
$MA_SAFE_POS_STOP_MODE and changes over into the SBH mode. If SBH is violated,
STOP B and A are initiated as stop response.
n = 0, 1 stand for the lower limit value of SE1, SE2
If a lower or identical value is entered in MD36934 $MD_SAFE_POS_LIMIT_PLUS[n] than in
MD36935 $MA_SAFE_POS_LIMIT_MINUS[n], then a parameterizing error is displayed.

$MA_SAFE_CAM_POS_PLUS[0...29]
Plus cams position for Safe Cams
Min. input limit: -2147000
This MD specifies the plus cam position for Safe Cams SN1+, SN2+, SN3+, ...
For the "Safe Cams" function, the following applies:
If the actual position is greater than this value when the Safe Cam function is active (MD36901
$MA_SAFE_FUNCTION_ENABLE), then the appropriate safety-relevant output signal (SGA)
is set to 1.
If the actual position falls below this value, SGA is set to 0.
n = 0, 1, 2, 3 stand for the plus cam position of SN1+, SN2+, SN3+, SN4+
For the "Safe Cam Track" function, the following applies:
If the "Safe Cam Track" function is enabled (MD36903 $MA_SAFE_CAM_ENABLE), then the
safety-related output signals "cam track" and "cam range" are set corresponding to the pa‐
rameterization in MD36938 $MA_SAFE_CAM_TRACK_ASSIGN[n].
n = 0 ... 29 stand for the plus cam position of SN1+, ..., SN30+
