$MA_SAFE_CAM_POS_MINUS[n]: 0 ... 29
Minus cam position for safe cams
Min. input limit: - -2 147 000
Protection level: 7/2
This MD specifies the minus cam position for safe cams SN1- -, SN2- -, SN3- -, ...
For the "safe cams" function, the following applies:
If the actual position is greater than this value when the safe cam function is active
($MA_SAFE_FUNCTION_ENABLE), then the appropriate safety- -related 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 minus cam position of SN1- -, SN2- -, SN3- -, SN4- -
For the "safe cam track" function, the following applies:
If the "safe cam track" function is enabled ($MA_SAFE_CAM_ENABLE), then the safety- -
related output signals "cam track" and "cam range" are set corresponding to the parameter-
ization in MD $MA_SAFE_CAM_TRACK_ASSIGN[n].
n = 0 ... 29 stand for the plus cam position of SN1- -, ..., SN30- -
