- Index table indexing function and other functions
Item Explanation
Relative position display This value can be rounded by setting bit 2 (REL) of parameter No.
7602.
Absolute position display This value is rounded at all times.
Automatic return from the reference
position (G29)
Second reference position return (G30)
Return is impossible.
Machine coordinate system selection
(G53)
No movement is allowed.
Single direction positioning (G60) Not specifiable
Second auxiliary function Ensure that a second auxiliary function axis name does not duplicate
an indexing axis name.
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.
