Selection of Mode and Operating Submode
The mode for the module and the operating submodes for the individual axes are set by the
user (see planning instruction WF 725/WF 726).
For traversing, the mode 0 and the submode 3 must be set.
When the operating submode or the mode is changed, the present block information is
changed, and START is set back:
•
When the submode is changed, the feed rate and the path are deleted. The first G-
function is preset with G90.
•
When the mode is changed, the feed rate and the path are deleted. The first G-function
is preset with G90.
When the submode is changed to 3 and the mode is changed to 0, the feed rate deposited in
the data words 6 and 7 of the function block WZ-M-A is transmitted to the present block
memory of the WF. In all other cases, the corresponding values have to transmitted again.
