4.6 Jog Move
Jog operation is commonly available at control panel of machine.
Its main function is to manually control the movement of motion
axis or function together with mechanical switch with digital input
to use DI signal as the jog movement startup signal. You may use
switch on control panel to operate jog movement by setting up
relevant parameters instead of coding control program.
There are two jog movement modes:
1. Continuous mode: This is similar to velocity movement
with given maximum speed and acceleration profile.
When JOG-ON signal (*) produces rising edge event
trigger then the specified control axis starts velocity
movement. When JOG-ON signal (*) produces falling
edge event trigger then the specified control axis starts
deceleration stop. See figure below:

NOTE NOTE
JOG-ON signal is a software digital signal where ON is
represented by value 1 and OFF by 0
