FANUC Series 30i-MODEL A
Index Table Indexing
If 0 is set in the M code for specifying negative direction rotation (parameter
No.5511), the rotation direction in G90 mode is determined by bit 3 (INC) of
parameter No.5500, as described below.
The rotation direction in G90 mode is
0: Not shortcut direction
1: Shortcut direction (The amount of movement is always less than
180 degrees.)
- Feedrate
The table is always rotated around the indexing axis in rapid traverse mode.
Dry run cannot be executed for the indexing axis.
- Reset
If a reset is performed in the clamp or unclamp completion wait state, the
clamp or unclamp signal is cleared, and the CNC exits from the completion
wait state.
- Index table indexing function and other functions
Item Explanation
Relative position display This value can be rounded by setting bit 1 (REL) of parameter
No.5500.
Absolute position display This value can be rounded by setting bit 2 (ABS) of parameter
No.5500.
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 0 (FUP) of parameter No. 1819 to 1. 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 4 (G90) of parameter No.5500 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.
