$MA_SAFE_CAM_MINUS_OUTPUT[0...3]
This machine data defines the outputs for the minus cams SN1- to SN4-.
= 0, 1, 2, 3 corresponds to the assignment for minus cams SN1-, SN2-, SN3-, SN4-
Structure: Coding of the output assignment
Signal means
= 0
Axis is located to the left of the cam (actual value < cam position)
= 1
Axis is located to the right of the cam (actual value > cam position)
If a cam is negated and applied to an output with an additional cam and the signals are AND'ed,
then this results in a single cam signal for area sensing purposes.
$MA_SAFE_ ACT_STOP_OUTPUT[0...3]
Output assignment of the active stop
Min. input limit: -
Assignment of the output signals to display the stops that are presently active.
Structure: Coding of the output assignment
Index = 0: Assignment for "STOP A/B is active"
Index = 1: Assignment for "STOP C is active"
Index = 2: Assignment for "STOP D is active"
Index = 3: Assignment for "STOP E is active"
$MA_SAFE_CROSSCHECK_CYCLE
Displays axis-specific crosswise comparison clock cycle
Min. input limit: -
Display data:
Effective axis-specific comparison clock cycle in seconds.
The clock cycle is obtained from MD10091 $MN_INFO_SAFETY_CYCLE_TIME and the num‐
ber of data to be compared crosswise.
$MA_SAFE_CONFIG_CHANGE_DATE[0...7]
Date/time of the last change SI-NCK-MD
Min. input limit: -
Protection level: 7/2
Protection level: 7/-
