11. PROGRAM COMMAND
783
CAUTION
1 The secondary auxiliary function can be used, but its
address must be different from that of the indexing axis.
2 If the incremental command is used for indexing of the index
table, the workpiece zero point offset value on the index
table axis must always be 0. That is, the machine
coordinate system must always agree with the workpiece
coordinate system of the index table axis.
3 The dry run signal DRN has no affect during positioning of
the B axis.
4 The machine lock signal MLK is functional during
positioning of the B axis.
NOTE
1 To specify a rotation axis as the index table indexing axis.
(Set the ROTx bit (bit 0 of parameter No. 1006)=“1”.)
2 The servo off signal for the index table indexing axis is
invalid.
3 Single direction positioning (G60) cannot be specified.
4 While the index table is being positioned, input signals that
reset the CNC, such as *ESP (emergency stop), ERS
(external reset), and RRW (reset & rewind), are functional.
When reset is applied to the CNC, indexing stops. Further,
if *SP (automatic operation stop signal) turns to “0”, axis
movement is stopped and the equipment enters the
automatic operation stop state.
If a stop at an any position is not suitable for the machine,
appropriate processing is required on the machine.
5 If a reset occurs while the system is awaiting the completion
of clamping or unclamping, the clamp or unclamp signal is
cleared. The CNC exits from the completion wait status.
6 Manual operation of jog feed, incremental feed and handle
feed cannot be used with the indexing axis, but manual
reference position return is possible. If reset is applied
during the movement of the indexing axis, then manual
reference position return should be performed.
7 No movement can be performed by automatic return from
the reference position (G29), return to the second reference
position (G30), or selection of the machine coordinate
system (G53).
8 Only the fourth axis can be used as the index table indexing
axis.
