$MA_SAFE_CAM_RANGE_BIN_OUTPUT_4[0...14]
Output assignment, cam range bit for cam track 3
Min. input limit: 0
This machine data specifies the outputs for the cam range bits of cam track 4.
Structure: 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:
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 4 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 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 parameterized.
$MA_SAFE_STANDSTILL_VELO_LIMIT
Switchover speed SBH/SG
Min. input limit: 0.0
min. Input limit: 0.0
When the axis/spindle speed drops below this limit, it is considered to be at a "standstill". A
switch over to Safe Operating Stop or to a lower velocity level is realized at the latest after the
time parameterized in MD37922 $MA_SAFE_STANDSTILL_DELAY expires. This premature
switchover is only realized if a velocity > 0.0 is parameterized in this MD.
MD37922 $MA_SAFE_STANDSTILL_DELAY and drive parameter p9567/p9569
$MA_SAFE_STANDSTILL_DELAY
Delay time, switchover to SBH/SG
Min. input limit: 0.0
Protection level: 7/2
Protection level: 7/2
Protection level: 7/2
