MANUAL OPERATION OF THE SERVO-CONTROLLED
TAILSTOCK (SERVO-CONTROLLED TAILSTOCK
SPECIFICATION)
14-1
Moving the Servo-controlled Tailstock in Manual Operation
The servo-controlled tailstock can be moved in the manual mode.
For the conditions that enable the tailstock to travel, refer to page B-65 (14-1-1).
For the automatic operation, refer to the PROGRAMMING MANUAL published
separately.
<In the rapid traverse mode/jog mode>
The servo-controlled tailstock can be moved by using the TAI or
−
switch provided on
the option panel. The tailstock is moved while the switch is held down.
In these modes, the settings of federate override and rapid traverse rate override are valid.
For the manual operation, even if the rapid override is set to 100%, the actual override
value is fixed at 50%.

<In the zero return mode>
The servo-controlled tailstock can be returned to the zero point by using the TAI or
−
switch in the zero return mode.
1)
Place the DOOR INTERLOCK key-switch in the
NORMAL
position.
2)
Close the front door.
3)
Place the PANEL key-switch in either of the positions indicated below.
(ON)
(PANEL/EDIT)
4)
Select the zero return mode (
) with the MODE selection switch.
5)
Set the rapid traverse rate to be used for zero return operation using the RAPID OVERRIDE
switches.
For the manual operation, even if this switch is set to 100%, the actual rapid traverse
override value is fixed at 50%.
6)
Press and hold down the TAI or
−
switch according to the direction for zero return
operation. The tailstock approaches the zero point at a rapid traverse rate, automatically
decelerates, and is stopped at the zero point.
If the switch for the direction opposite to the one for zero return operation is pressed, the
tailstock does not move.
When the tailstock has returned to the zero point, the indicator in the TAI switch is
lit.
