4) The first searching has failed and the second searching starts
POINT
If the first searching has failed, the second searching may not be processed in
the next cycle for a cam pattern with a feed stroke smaller than 100%. By setting
or positioning a cam standard position in advance, an intended cam axis one
cycle current value can be found in the first searching.
Once the first search fails, the cam standard position is automatically
updated and the second search starts so that "Feed current value - New
cam standard position" is within the feed stroke amount.
The cam axis one cycle current
value is restored with the first
feed current value that matched
and is found in the second
search.
