Chapter 11 Manual Control
11.1 Outline of manual control
11.1.1 Three manual control methods
"Manual control" refers to control in which positioning data is not used, and a
positioning operation is carried out in response to signal input from an external device.
The three types of this "manual control" are explained below.
[1] JOG operation
"JOG operation" is a control method in which the machine is moved by only a
movement amount (commands are continuously output while the JOG START
signal is ON). This operation is used to move the workpiece in the direction in
which the limit signal is ON, when the operation is stopped by turning the limit
signal OFF to confirm the positioning system connection and obtain the
positioning data address (refer to Section 13.7.4 "Teaching function").
M
Movement continues while
the JOG START signal is ON.

[2] Inching operation
"Inching operation" is a control method in which a minute movement amount of
command is output manually in operation cycle.
When the "inching movement amount" of the axis control data is set by JOG
operation, the workpiece is moved by a set movement amount. (When the
"inching movement amount" is set to "0", the machine operates as JOG
operation.)
M
JOG start signal is turned
ON to move the workpiece
by the movement amount
of pulses which is output in
operation cycle.
