1.3 Backward movement
The "backward movement " is that the program executed forward once is executed
backward by turning a manual handle in the negative direction.
The program can be executed backward only for the block executed forward. And, the
number of blocks for it is about 190 blocks. This block number changes by the content of the
commanded program.
The program is executed backward rapidly when a manual handle is turned to the negative
direction rapidly. And the program is executed backward slowly when a manual handle is
turned to the negative direction slowly. The distance traveled per pulse from manual handle
can switch magnification as well as a usual manual handle feed.
2. Details
2.1 Control by the manual handle
2.1.1 Program execution start
The checking mode signal MMOD<G0067#2> is set to "1" in the memory mode (MEM mode)
in order to change the checking mode. Then, the program execution is begun by turning ST
signal from "1" to "0".
If the manual handle check signal MCHK <G0067#3> is set to "1" at this time, the execution
of the program is controlled by a manual handle. The program is executed synchronizing
with rotation of a manual handle.
When a manual handle check signal MCHK<G0067#3> is set to "0", it is controlled as usual
execution.
Note
1.It is necessary to change to the checking mode in order to execute a program forward
and backward with a manual handle. The checking mode signal must not be turned to "1"
on during execution of program.
2.After the signal is turned to "0" during execution of the program, the program cannot be
executed forward and backward.
