$MA_SAFE_ACCEPTANCE_TST_TIMEOUT
Time limit for the acceptance test duration
Min. input limit: 5
Protection level: 7/2
On the NCK side, a time limit can be entered for the duration of an acceptance test. If an
acceptance test takes longer than the time specified in MD 36958, then the NCK terminates
the test.
The acceptance test status is set to zero on the NCK side. If the acceptance test has been
reset, then on the NCK and drive sides, SI Power On alarms are again changed over from
being able to be acknowledged with a reset to being able to be acknowledged with Power
On.
NCK clears Alarm 27007 and the drive clears Alarm 300952.
This MD is also used to limit the duration of an acceptance test SE (safe limit positions).
After the programmed time has expired, the acceptance test SE is interrupted and Alarm
27008 is cleared. The software limit positions are then again effective – the same as they
are entered in the machine data.
$MA_SAFE_STANDSTILL_VELO_TOL
Shutoff speed for pulse suppression
Min. input limit: 0.0
Protection level: 7/2
When the axis/spindle speed drops below this limit, it is considered to be at a "standstill". In
the STOP B mode the pulses are then cancelled (as a result of the transition to STOP A).
