MANUAL CONTROL
This chapter describes the details and usage of the manual control.
In the manual control, pulse output commands are issued during the JOG operation and inching operation executed by
turning on JOG start signal, or from the manual pulse generator connected to the RD75.
The chapter describes the manual control using a program from 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 in which a limit signal is turned on when the
operation is stopped by turning off the limit signal to check the positioning system connection and obtain the positioning data
address (Page 284 Teaching function).

Inching operation
In the inching operation, pulses for a minute movement amount are output manually at 1.77ms. 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.)
