$MA_SAFE_POS_LIMIT_MINUS[n]: 0 ... 1
Lower limit value for safe limit position
Min. input limit: - -2 147 000
Protection level: 7/2
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
$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 MD $MD_SAFE_POS_LIMIT_PLUS[n] than in MD
$MA_SAFE_POS_LIMIT_MINUS[n], then a parameterizing error is displayed.
MD 36962: $MA_SAFE_POS_STOP_MODE
MD 36934: $MA_SAFE_POS_LIMIT_PLUS[n]
/FBSI/ see Chapter 6.7: "Safe software limit switches (SE)"
$MA_SAFE_CAM_POS_PLUS[n]: 0 ... 29
Plus cam position for safe cams
Min. input limit: - -2 147 000
Protection level: 7/2
This MD specifies the plus cam position for safe cams SN1+, SN2+, SN3+, ...
For the "safe cams" function, the following applies:
If the actual position is greater than this value when the safe cam function is active
($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 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 ($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+
