Machine data

3.2 General machine data

1:
programmed end point, irrespective of where the machine actually is (e.g. as a result
of the tool radius compensation). The distance to go is the same as the actual distance
to be traversed. This means that the displayed actual postion has to be the same as
the displayed end position minus the distance to go, irrespective of the actual
machine position. If the block end points are changed by chamfers, radii, contour
definitions, splines or SAR in comparison to the NC programm, then these changes are
reflected in the display as if thay had been programmed. This does not apply to changes
resulting from tool radius compensation or smoothing.

Description:
This machine data specifies the division ratio used for activating the communication
task in the non-cyclic time level. This allows the time share of preparation in the
non-cyclic time level to be increased, which reduces block change times. This slows
down external communication (file transfer), especially during program execution
(group-by-group reload).

PLC_TASK_RUNTIME_WARNING

s Prewarning limit for computation time exceeded SW-PLC2xx
-
- -
Description:
The machine data defines the duration for the prewarning of the computation time
exceeded for SW-PLC2xx in seconds. After this time has expired, SW-PLC2xx generates
display alarm 400026 "PLC cycle time has exceeded the alarm threshold".

GEAR_CHANGE_WAIT_TIME

s Gear stage change waiting time
-
- -
Description:
External events which trigger reorganization, wait for the end of a gear stage change.
GEAR_CHANGE_WAIT_TIME now determines the waiting time for the gear stage change. Time
unit in seconds.
When this time expires without the gear stage change having been terminated, the NCK
reacts with an alarm.
Among others, the following events will cause reorganization:
User ASUB
Mode change
Delete distance-to-go
Axis replacement
