SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 05.2008 Edition
$MA_SAFE_CAM_RANGE_OUTPUT_3[0...3]
Output assignment, cam range for cam track 3
Min. input limit: –
Protection level: 7/2
This machine data specifies the outputs for the cam range of cam track 3.
Configuration: see $MA_SAFE_SVSS_STATUS_OUTPUT
n = 0, 1, 2, 3 corresponds to the 4 bits to specify the range on cam track 3
Bit 3 Bit 2 Bit 1 Bit 0

The cam range is defined using the following machine data:
MD 36938: $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 3.
= 15 axis is located in the range to the right of the outermost cam of cam track 3
The "safe cam track" function is enabled using MD 36903 $MA_SAFE_CAM_ENABLE.
If the MD bits 31 are set, then the signal is processed inverted.
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.
MD 37900: $MA_SAFE_CAM_TRACK_OUTPUT
$MA_SAFE_CAM_RANGE_OUTPUT_4[0...3]
Output assignment, cam range for cam track 4
Min. input limit: –
Protection level: 7/2
This machine data specifies the outputs for the cam range of cam track 4.
Configuration: see $MA_SAFE_SVSS_STATUS_OUTPUT
n = 0, 1, 2, 3 corresponds to the 4 bits to specify the range on cam track 4
