2.3 Direction change prohibition
The direction change prohibition is a state not being changed for the direction where the
program is executed.
In the state, even if the rotating direction of a manual handle is reversed, the reversed
rotation is disregarded. A manual handle must be rotate in the same direction as present
direction for removing this state.
The direction change prohibition can be confirmed by output signal MNCHG(F0091#1) .
It becomes the change prohibition state under the following condition.
!
While the block with the code waiting for FIN is executing
!
After a block has done and until the next block begins to operate
!
During thread cutting
!
During stopping by the single block or the feed hold
2.4 Backward movement prohibition
The backward movement prohibition is a state that the program cannot be executed from a
certain block backward. In this state, the negative rotation of a manual handle is
disregarded, and the only positive rotation is effective. The program must be executed
forward by rotating a manual handle in the positive direction for removing this state.
The backward movement prohibition can be confirmed by output signal MRVSP(F0091#2).
If the following blocks are executed in backward movement, backward movement prohibition
signal becomes to “1”.
!
Program number block of main program (O...)
!
Over the maximum number of the blocks for reverse movement
!
Blocks other than block which includes following G code and modal information
