INSTALLATION PROCEDURE
302.061
Defines the duration of the ON impulse received by the lathe to turn the spindle.
It is required to facilitate the feed of shaped bars into the collet.
Stage sequence:
– The bar moves forward in the slow speed section (
parameter 11
);
– The bar meets the obstacle (the collet) and the lathe receives the spindle rotation impulse of the set duration;
– The spindle slows down and stops (having the time defined at
parameter 19
);
– The bar receives the feed impulse;
– If the bar enters the collet, the cycle continues;
– If the bar does not enter into the collet, the previous stages are repeated.
Defines the duration of the OFF impulse received by the lathe to slow down
and stop the spindle before the subsequent rotation impulse (see description
of stages at
parameter 18
).
When the bar reaches its facing position (
parameter 2
), there can be a delay
of the lathe “CYCLE START” signal corresponding to the value set (K15).
Example of application: A “CYCLE START” signal delay may be neces-
sary if the spindle requires some time to reach its correct operating spe-
ed.
Defines bar remnant handling.
