[Function][Operation]
When transferring external workpiece coordinate offset (EXT) in the pallet 4 page registration, turn this signal ON. NC
starts transfer processing at the rising edge of this signal.
When the external workpiece coordinate transfer completion signal is turned ON, turn this signal OFF.
It takes approx. 8ms from the start to the end of transfer processing. If the transfer completion signal is not turned ON
even after 8ms has passed since the transfer ready signal was turned ON, reconsider the value of R register 4100 and
4102.
NC turns the external workpiece coordinate transfer completion signal OFF at the falling edge of this signal.
When turning the transfer ready signal ON from the machining program, recalculation request and M function finish (FIN1
or FIN2) must be turned ON after the external workpiece coordinate transfer completion signal is turned ON.
When recalculation is not requested, operation of the pre-read machining program will be carried out using the external
workpiece coordinate offset prior to the change.
When M function has been completed before transfer is completed, the external workpiece coordinate offset data to be
used in the machining program will not be changed from the one prior to the change until the transfer completion signal is
turned ON.
This signal must be turned ON while the external workpiece coordinate transfer completion signal is OFF.

After the signals relating to pallet information in the machine
and index plane of the pallet in the machine are set, PLC sets
this signal.
When this signal is turned to "1", NC system transfers the ex-
tension workpiece coordinate offset data to external work-
piece coordinate offset (EXT).
