14.3.2.4 Deleting Thread Recutting Positions

[Operation to delete thread recutting positions]
(1) Set the delete bit (bit1) in R2626 (thread recutting command).
(2) Turn ON the R2626 (thread recutting command) command execution bit (bit7) and delete the thread recutting position.
-> Bit1 in R648 (thread recutting status) turns ON if operation completes successfully.
If an error occurs, bit7 in R648 (thread recutting status) and the bit corresponding to the error turns ON.
Executing the deletion process deletes the thread recutting positions (lead axis machine positions and spindle positions) for
this part system. Deleting the thread recutting positions turns OFF the thread recutting enabled bit (bitF) in R649 (thread
recutting execution state) and clears R650 (thread recutting spindle number) and R651 (thread recutting lead axis number).
Deletion of thread recutting positions cannot be performed during the thread recutting process. If the thread recutting process
is in operation, turn OFF the thread recutting function enable bit (bitF) in R2627 (thread recutting execution operation) and
then perform the operation to delete the thread recutting position.

14.3.2.5 Transitioning to the Thread Recutting State

Turn ON the thread recutting function enable bit (bitF) in R2627 (thread recutting execution operation). BitF in R649 (thread
recutting execution status) turns ON if the thread recutting position is stored.
The thread recutting process is performed when the thread recutting command is executed while bitF in R649 (thread
recutting execution state) is turned OFF. Executing the thread cutting command while bitF in R649 (thread recutting execution
state) is turned OFF and bitF in R2627 (thread recutting execution operation) is turned ON results in generation of the
operation error (M01 1027 ).

14.3.2.6 Disabling Thread Recutting Operations

Turning OFF the thread recutting function enable bit (bitF) in R2627 (thread recutting execution operation) while the thread
recutting function enabled bit (bitF) in R649 (thread recutting execution state) is on cancels the thread recutting state and
causes bitF (thread recutting execution operation) in R649 to turn OFF.
