4 Data Descriptions
4.1 Machine data
36958 $MA_SAFE_ACCEPTANCE_TST_TIMEOUT
MD number Time limit for the acceptance test duration
Default: 40
Change becomes effective after POWER ON:
Data type: DOUBLE
Meaning On the NCK side, a time limit can be specified for the duration of an acceptance test
(there is a drive machine data MD 1358 that corresponds with this, in which the same time
must be entered). If an acceptance takes longer than the time specified in MD 36958,
then the NCK terminates the test. The acceptance 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 a POWER ON.
NCK clears Alarm 27007 and the drive, Alarm 300952.
This MD is also used to limit the duration of an acceptance test SE. After the program
time has expired, the acceptance test SE is interrupted and Alarm 27008 is cleared. The
software end positions are then again effective the same as they are used in the machine
data.

36960 $MA_SAFE_STANDSTILL_VELO_TOL
MD number Shutdown speed for pulse cancellation
Default: 0
Change becomes effective after POWER ON:
Data type: DOUBLE
Meaning When the axis/spindle speed drops below this limit, it is considered to be at a "standstill".
In STOP B mode, the pulses are then cancelled (through transition to STOP A).
Corresponds with ... MD 36956: $MA_SAFE_PULSE_DISABLE_DELAY
36961 $MA_SAFE_VELO_STOP_MODE
MD number Stop response, safely reduced speed
Default: 5
Change becomes effective after POWER ON:
Data type: BYTE
Meaning The ones position defines the selection of the stop responses when the safely-reduced
speed is exceeded.
The tens position defines the behavior when the drive bus fails if a time greater than 0
was parameterized in $MN_SAFE_PULSE_DIS_TIME_BUSFAIL.
Special case: For a value of 5 in this MD, the stop response for each SG stage is
selectively defined $MA_SAFE_VELO_STOP_REACTION.
