Item Explanation
Operation during index table indexing
axis movement
Unless otherwise processed by the machine, feed hold, interlock, and
emergency stop can be executed during index table indexing axis
movement.
Machine lock can be executed after indexing has been completed.
Servo-off signal Disable the servo-off signal for the index table indexing
axis. That is, set bit 1 (SVF) of parameter No. 1802 to 0.
Usually, the index table indexing axis is in the servo-off
state.
Incremental command for the
index table indexing axis
When incremental programming is used for index table
indexing (when bit 3 (G90) of parameter No. 7602 is set to
0), the workpiece origin offset of the index table axis must
always be 0. That is, there must always be a match
between the workpiece coordinate system and machine
coordinate system of an index table indexing axis.
Operation for an index table
indexing axis
Operation in jog/step/handle mode for an index table
indexing axis is disabled. However, manual reference
position return is possible. If the axis selection signal is set
to 0 during manual reference position return, the movement
stops immediately, and the clamp command is not
executed.
Limitation
- Simultaneous specification together with other controlled axes
Specify an indexing command singly in a block. If an indexing
command is specified in a block that specifies other controlled axes as
well, an alarm (PS0564) is issued.
- Command specifying zero move amount
When the amount of movement is 0, a clamp/unclamp operation is not
performed. In automatic reference position return based on G28,
clamp/unclamp is performed even if the amount of movement is 0.
CAUTION
If a reset is made during index table indexing axis
movement, a reference position return operation
must always be performed before index table
indexing.
NOTE
Dry run cannot be used to position the index table
indexing axis.
