Precautions on Using the Spindle OFF Mode Function
The items to be taken into consideration when checking a program by using the spindle OFF
mode function are indicated below.
1.
The valid/invalid state of the spindle OFF mode function cannot be changed during
automatic operation.
2.
The spindle OFF mode function is set to invalid when the power is turned on.
3.
While the spindle is rotating or while the rotary tool spindle is rotating (MC type), it is
not allowed to change the spindle OFF mode function valid.
4.
When the spindle OFF mode function is valid, manual rotation of the spindle and the
rotary tool spindle (MC type) is not possible. Note that jogging the spindle and the
rotary tool spindle (MC type) is allowed.
5.
When the spindle OFF mode function is valid, coolant is supplied when the
(ON) switch is pressed.
6.
When the spindle OFF mode function is valid, an alarm (EX4014) occurs when the
(ST) switch is pressed if a workpiece is clamped in the chuck (the STATUS
indicator
[CHCL]
is lit).
7.
The dry run function is automatically made valid when the spindle OFF mode
function is made valid. In this state, it is possible to make the dry run function valid/
invalid by pressing the dry run switch
.
8.
In the spindle OFF mode function valid state, if an axis move command is executed
in the feed per revolution mode with the dry run function made invalid, axis
movement stops.
9.
If M10 (chuck clamp) command is executed in the spindle OFF mode function valid
state, the STATUS indicator
[CHCL]
is lit after the completion of the specified
operation.
10.
If a macro program to check the correct pushing of a workpiece to the chuck is
executed in the spindle OFF mode function valid state, the operation completion
signal is not output. This does not cause an alarm, however, and the program
advances to the next block. (S type)
11.
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.
