A-32 OPERATION PANELS
<When the chuck jaw stroke end detection function is valid>
The spindle cannot be started unless a workpiece is clamped in the chuck within an appropriate
master jaw stroke range.
<When the chuck jaw stroke end detection function is invalid>
The spindle can be started as long as the chuck is in the clamped state even if no workpiece is
mounted in the chuck.

Zero Point Adjustment
Since dogless type zero return method is used, axis movement becomes impossible if the present
position data is lost due to a trouble or other reasons.
The zero point adjustment function is used to allow axis movement when adjusting the zero point
to establish the present position under the condition that the present position data has been lost
and axis movement disabled.
It is made valid or invalid on the OPERATION PANEL screen.
Function selection key
(CUSTOM1)
[OPE. PANEL]
Usually, "INVALID" is set.
<When the zero point adjustment function is valid>
When the zero point adjustment function is valid, axis movement is enabled even if the present
position data is lost.
However, the rapid traverse rate is clamped at
(fine feed).
If "VALID" is set for ZERO POSITION SET while the present position data is lost,
interlocks related with axis movement are all canceled.
Therefore, move an axis very carefully. If an axis is moved carelessly, the turret or
carriage might be hit against the cover causing damage to the machine.
When the present position is established after the adjustment of the zero point, the setting
for ZERO POSITION SET is automatically returned from VALID to INVALID.
<When the zero point adjustment function is invalid>
Axis movement is not permitted if the present position data is lost.
WARNING
If the chuck jaw stroke end detection function is INVALID, the spindle
starts even if a workpiece is clamped in the chuck near the master jaw
stroke end, thereby allowing the workpiece to fly out causing accidents
involving serious injuries or damage to the machine. Therefore, the
function must be set "VALID" when a workpiece is mounted in the
machine.
