OPERATION INFORMATION
302.035
It sets the bar/headstock synchronizing device operation mode.
1 - (continuous)
2 - (intermittent)
3 - (released)
4 - (locked)
5 - (sync. with open collet)
This parameter is active when the
parameter 33
is in mode
2 - (SLIDING)
o
3 - (SLIDING BUSH).
1 - (continuous)
The bar/headstock synchronizing function is overridden, the bar receives a contin-
uous thrust from the feed motor. The feed motor speed can be adjusted: when the
collet is open with
parameter 7
, when the collet is closed with
parameter 27
.
2 - (intermittent)
The bar/headstock synchronizing function is enabled when the collet is closed (the
feed motor is stopped) and disabled when the collet is open (feed motor running).
INFORMATION: to prevent an excessive thrust in the cutting tool , it is advis-
able to reduce the open collet speed value (parameter 7). E.g.: set the value 2.
3 - (released)
The bar/headstock synchronizing function is enabled when the collet is closed (the
feed motor is stopped) and disabled when the collet is open (feed motor stopped).
4 - (locked)
The bar/headstock synchronizing function is enabled when the collet is closed (the
feed motor is stopped) and disabled when the collet is open (feed motor stopped).
5 - (sync. with open collet)
This mode is only active when
parameter 33
is in mode
3 - (SLIDING BUSH)
.
The bar/headstock synchronizing function is enabled when the collet is open (the
feed motor is stopped) and disabled when the collet is closed (feed motor
stopped).
INFORMATION: for modes 3 - (released), 4 - (locked) and 5 - (sync. with open
collet). The feed motor is stopped both when the collet is closed and when the
collet is open, which can cause extraction of the bar from the bar-pusher collet
due to backlash among the various parts (bar-pusher, revolving tip, feed chain
etc.). To prevent this, a low time setting can be entered in parameter 9: after col-
let closure, the feed motor will be operated for the selected time and make up
for any backlash among the various parts.
