The route of forward movement
The route of backward
Please use the interpolation type positioning to ward off danger. (Set the bit 1 (LPR) of parameter No.
1401 to 1)
If non-linear interpolation type positioning is used, direction change is prohibited at the end of movement
along any axis.

Threading
When bit 6 (HRG) of parameter No.6403 is set to 0, threading (G32,G76,G84,G88,G92)is always
executed at 100% override speed. That is to say, a pulse generated by a manual handle is ignored in
executing a threading block. In thread cutting cycle, the pulse is invalid at the time actually cutting thread,
but the one are valid in the other movements.
When bit 6 (HRG) of parameter No.6403 is set to 1, it is possible to move backward and re-forward in the
block of threading. However, threading cycle (G92) and multiple threading cycle (G76) are excluded.
WARNING
When the parameter HRG is set to 1, detach the work if you execute the program
including the threading because the synchronization of the spindle and the feed
axis is not maintained at threading block. The machining of work is impossible.
-
Rigid tapping (lathe system)
When bit 6 (HRG) of parameter No.6403 is set to 1, it is possible to move backward and re-forward in the
block of rigid tapping. However, it is not possible to move backward by passing an on-off command of
the rigid tapping mode.
WARNING
When the parameter HRG is set to 1, detach the work if you execute the program
including the rigid tapping. The machining of work is impossible.
-
Tapping mode (G63)
When bit 6 (HRG) of parameter No.6403 is set to 1, it is possible to move backward and re-forward in the
tapping mode.
WARNING
When the parameter HRG is set to 1, detach the work if you execute the program
including the tapping mode because the synchronization of the spindle and the
feed axis is not maintained. The machining of work is impossible.
-
Macro variable
In macro statement, the setting, operation, and so on of the macro variable is executed in only first
forward movement. That is to say, the setting, operation, and so on of the macro variable is never
executed in the block executing them once.
-
Macro modal call
Manual handle retrace function is effective to macro modal call (G66,G66.1).
-
Macro executor (execution macro)
Manual handle retrace function is effective while the execution macro of macro executor is called.
