C-28 CHUCKING
<Setting VALID/INVALID for CHUCK STROKE END>
Since the machine is equipped with the chuck jaw stroke end detecting switches, chuck clamp
operation is not completed unless the workpiece is clamped by the chuck within an appropriate
master chuck jaw stroke range. Accordingly, operation without a workpiece in the chuck, such as
shaping the soft jaws or no-load running of a program, is impossible. To allow operation without a
workpiece in the chuck, a function to invalidate the chuck jaw stroke end detection function is
provided.
If the setting for CHUCK STROKE END is changed to "INVALID", the chuck clamp
operation is completed in response to the chuck clamp operation disregarding of the
signals from the chuck jaw stroke end detecting switches.
The chuck jaw stroke end detection function is made valid or invalid by setting CHUCK STROKE
END to VALID or INVALID on the OPERATION PANEL screen.
For the chuck jaw stroke end detection function, refer to page A-31 (5-6-12).
If the setting for the CHUCK STROKE END is "INVALID", it is automatically changed to
"VALID" in the following cases:
1.
After the power is turned on
2.
After resetting emergency stop state
3.
When the M02 or M30 command is read.
4.
When the chuck is unclamped.
For 3 and 4, it is possible to make automatic switching to "VALID" impossible by making
the appropriate parameter setting. For details, contact Mori Seiki.
