CHAPTER THREE MANUAL OPERATION
3.1 JOG Feed/Incremental Feed
Brief
JOG feed
The feed axis and direction selection signal on the operation panel is set to 1 in the JOG
mode. The machine is consecutively moved along the selected axis in its direction.
Incremental feed
The feed axis and direction selection signal on the operation panel is set to 1 in
the incremental feed mode. The machine moves one step along the selected
axis in its direction; the least distance of the machine movement is the least input
increment, each step has the least input increment with 10, 100 or 1000 folds.
JOG feed and incremental feed are absolutely same, other than the feed distance selection
method. In JOG feed, the machine can be consecutively feed when the feed axis (

machine is single step feed. The JOG feedrate can be adjusted by its override disk.
The machine moves based upon the rapid feedrate by the rapid feed selection switch; however,
it is regardless of the JOG feed velocity override signal.
The single-step distance can be selected by the incremental step

[Function]
Select the required feed axis and direction in the JOG feed or
incremental feed. The “+” and “-” in the signal name are indicated as
feed direction, the digit is corresponding with the controllable axis.
