MANUAL CONTROL
This chapter describes the details and usage of the manual control.
Manual control includes a manual pulse generator operation to generate pulse output commands that are issued during the
JOG and inching operations which are executed by turning on JOG start signal, or from the manual pulse generator.
The chapter describes manual control used via a program loaded in the CPU module.

Overview of the Manual Control
Three manual control methods
When the manual control is used, the positioning operation is performed in response to a signal input from an external source.
Positioning data is not used.
Manual control is classified into three controls: JOG operation, inching operation, and manual pulse generator operation.
JOG operation
In the JOG operation, the machine is moved only for a movement amount (pulses are continuously output while JOG start
signal is on). This control method is used to move the workpiece in the direction corresponding to the limit signal if turned on
when operation has stopped due to the limit signal turning off to check the positioning system connection and obtain the
positioning data address (Page 282 Teaching function).
Movement continues while the JOG start signal is on

Inching operation
In the inching operation, pulses for a minute movement amount are output manually at 1.77 ms. By setting Inching movement
amount of the axis control data in the JOG operation, the workpiece moves only for the set movement amount. (However, the
JOG operation is performed when Inching movement amount is set to 0.)
Movement only occurs for the amount of pulses output for
1.77 ms after the JOG start signal turns on.
