$MA_SAFE_CAM_RANGE_OUTPUT_4[0...3]
This machine data specifies the outputs for the cam range of cam track 4.
Structure: see $MA_SAFE_SVSS_STATUS_OUTPUT
n = 0, 1, 2, 3 correspond to the 4 bits to specify the range on cam track 4
Bit 3 = 0, bit 2 = 0, bit 1 = 0, bit 0 = 0: Cam range 0 is active
Bit 3 = 0, bit 2 = 0, bit 1 = 0, bit 0 = 1: Cam range 1 is active
up to ...
Bit 3 = 1, bit 2 = 1, bit 1 = 1, bit 0 = 1: Cam range 15 is active
The cam range is defined using the following machine data:
MD36938 $MA_SAFE_CAM_TRACK_ASSIGN[n]
Signal means
= 0...14, axis is located in the range of the cam that was assigned to range ID 0...14 on cam
track 4.
= 15 axis is located in the range to the right of the outermost cam of cam track 4
Note:
The "Safe Cam Track" function is enabled using MD36903 $MA_SAFE_CAM_ENABLE.
If not all of the 4 bits are assigned, then under certain circumstances, it cannot be uniquely
and clearly identified as to which cam range is active.
MD37900 $MA_SAFE_CAM_TRACK_OUTPUT
$MA_SAFE_CAM_RANGE_BIN_OUTPUT_1[0...14]
Output assignment, cam range bit for cam track 1
Min. input limit: 0
This machine data specifies the outputs for the cam range bits of cam track 1.
Structure: see $MA_SAFE_SVSS_STATUS_OUTPUT
Field index n corresponds to the parameterizable cam range numbers on cam track 1.
The cam range number is defined using the following machine data:
MD36938 $MA_SAFE_CAM_TRACK_ASSIGN[0...29]
Signal means
= 0, axis is not located on the cam with cam range number n
= 1, axis is located on the cam with cam range number n
Example:
The signal that is addressed using field index 5 goes to 1 if the axis is located at the cam that
is assigned to cam track 1 by parameterizing the cam range number 5.
Note:
The "Safe Cam Track" function is enabled using MD36903 $MA_SAFE_CAM_ENABLE.
If the cam range number n is not parameterized on cam track 1 then the signal of field index
n can never go to 1. The output MD with field index n must in this case not be parameterized.
Protection level: 7/2
