This function is available when the lathe handles the workpiece feeding.
In this case the bar feeder, having loaded the bar, stores the bar working len-
gth and consequently the number of workpieces.
The bar pusher moves back to the zero point and signals the end of bar to
the lathe only when the stored workpiece amount has been reached.
Then, according to the value set in
parameter 21
(REMNANT HANDLING),
the bar feeder actuates the bar change.
INFORMATION: Once this parameter values are modified, the operator
must press the key to reset the previously set values.
INFORMATION: The subparameter "Sub-spindle feeding torque" must
be set at a minimum value (0=MAX, 500=MIN). This will allow the bar pu-
sher to reach the bar.
CAUTION: for a correct operation, the feed chain must be adequately tensioned.
