MANUAL CONTROL
The details and usage of manual control are explained in this chapter.
In manual control, commands are issued during a JOG operation and an inching operation executed by the turning ON of the
JOG start signal, or from a manual pulse generator connected to the Simple Motion module.
Manual control using a program from the CPU module is explained in this chapter.

Outline of Manual Control

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.
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 (Page 285 Teaching function).

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.)
