A-44 OPERATION PANELS
When checking a new program, automatic operation is executed without rotating the spindle and
supplying coolant to check tool offset amounts, interference between tools and a chuck, etc.
For the procedure to check a program without chucking a workpiece, refer to page F-11
<When the spindle OFF mode function is valid>
When the spindle OFF mode function is made valid, the dry run function also becomes valid and
the indicator above the
(SP) switch and the indicator in the dry run switch
blink.
If automatic operation is executed in this state, the program advances to the next block without
executing the M code functions indicated in the table above.
Although axis movement commands are executed, the axes are moved at the feedrate set by the
OVERRIDE dial since the dry run function is valid.
1.
It is not possible to execute automatic operation with a workpiece clamped in the
spindle chuck when the spindle OFF mode function is valid.
2.
Since M329 is an M code that is processed at the NC unit, programs that include an
M329 command cannot be used in the spindle OFF mode.
<When the spindle OFF mode function is invalid>
When the spindle OFF mode function is made invalid, the dry run function also becomes invalid
and the indicator above the
(SP) switch and the indicator in the dry run switch
go off.
In this state, normal operation is possible.
