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 200 blocks.
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.
2. Details
2.1 Control by the manual handle
2.1.1 Program execution start
The checking mode signal G0067#2(MMOD) 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 (G0067#3 MCHK) is set to “1” at this time, the execution
of the program is controlled by a manual handle. That is to say, the program is executed
synchronizing with rotation of a manual handle.
When a manual handle check signal (G0067#3 MCHK) is set to “0”, it is controlled as usual
execution.
Note
2. 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.
3. After the signal is turned to “0” during execution of the program, the program cannot be
executed forward and backward.
