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 source.
The three types of this "manual control" are explained below.
(1) Manual control classification
(a) JOG operation
"JOG operation" is a control method in which the machine is moved by only a movement amount (pulses are
continuously outputted 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 586, Section 12.7.4).
(b) Inching operation
"Inching operation" is a control method in which a minute movement amount of pulses is output manually at
1.8ms. 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 operation is
performed as the JOG operation.)
