INSTALLATION PROCEDURE
302.061
As far as “BAR CHANGE-OVER” signal control is concerned, this option dif-
fers from option
1 - (RETURN)
.
Said signal controls more bar-pusher feeding movements, whenever they are
required by lathe during workpiece machining.
In this condition, the “BAR CHANGE” controls the feeding of the bar feeder
and disables its return. The bar feeder return depends on the “FEEDING” si-
gnal.
