SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 05.2008 Edition
$MA_SAFE_CAM_RANGE_BIN_OUTPUT_3[0...14]
Output assignment, cam range bit for cam track 3
Min. input limit: –
Protection level: 7/2
This machine data specifies the outputs for the cam range bits of cam track 3.
Configuration: see $MA_SAFE_SVSS_STATUS_OUTPUT
Field index n corresponds to the parameterizable cam range numbers on cam track 3.
The cam range number is defined using the following machine data:
MD 36938: $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 3 by parameterizing the cam range number 5.
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 the cam range number n is not parameterized on cam track 3 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 parameter-
ized.
$MA_SAFE_CAM_RANGE_BIN_OUTPUT_4[0...14]
Output assignment, cam range bit for cam track 3
Min. input limit: –
Protection level: 7/2
This machine data specifies the outputs for the cam range bits of cam track 4.
Configuration: see $MA_SAFE_SVSS_STATUS_OUTPUT
Field index n corresponds to the parameterizable cam range numbers on cam track 4.
The cam range number is defined using the following machine data:
MD 36938: $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 4 by parameterizing the cam range number 5.
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 the cam range number n is not parameterized on cam track 4 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 parameter-
