1. General
In this function, the program can be executed both forward and backward with a manual
handle (manual pulse generator) under automatic operation.
Therefore, errors of a program, interference, and so on can be checked easily by working a
machine actually.
1.1 Checking mode
In this mode, the program can be executed forward and backward and the program can be
checked.
To change to the checking mode, it is necessary that the mode is changed to the memory
mode (MEM mode) and the checking mode signal MMOD<G0067#2> is set to "1". This
function makes the data to execute the program backward when the program is executed
forward in the checking mode.
To working a machine synchronizing with a pulse generated by a manual handle in the
checking mode, the manual handle check signal MCHK <G0067#3> is set to "1" in addition
to the above-mentioned. As a result, it becomes possible to check the program with a
manual handle.
1.2 Forward movement with a manual handle
The "forward movement" is that the program is executed forward by turning a manual
handle in the positive direction (when the manual handle check signal is set to "1".) or in no
relation to rotation of a manual handle (when the manual handle check signal is set to "0".).
When the manual handle check signal is set to "1", the execution speed of the program is
proportional to the number of rotations of a manual handle. The program is executed
forward rapidly when a manual handle is turned to the positive direction rapidly. And, the
program is executed forward slowly when a manual handle is turned to the positive
direction slowly. The distance traveled per pulse from manual handle can switch
magnification as well as a usual manual handle feed.
When the manual handle check signal is set to "0", the execution of the program is
controlled as well as automatic operation.
