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 (pulses are continuously transmitted 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 12.7.4 "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 
pulses is output manually in one control 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 functions as JOG 
operation.)

JOG start signal is turned
ON to move the workpiece
by the movement amount
of pulses which is output in
one control cycle.
