2.3 Operating modes
2.3.1 General
You can work in three different operating modes.
"JOG" mode
"JOG" mode is used for the following preparatory actions:
Approach reference point, i.e. the machine axis is referenced
Preparing a machine for executing a program in automatic mode, i.e. measuring tools,
measuring the workpiece and, if necessary, defining the work offsets used in the program
Traversing axes, e.g. during a program interruption
Positioning axes
Select "JOG"
Press the <JOG> key.
"Ref Point" submode
The "REF POINT" submode is used to synchronize the control and the machine. For this
purpose, you approach the reference point in "JOG" mode.
Selecting "REF POINT"
Press the <REF POINT> key.
"REPOS" submode
The "REPOS" submode is used for repositioning to a defined position. After a program
interruption (e.g. to correct tool wear values) move the tool away from the contour in "JOG"
mode.
The distances traversed in "JOG" mode are displayed in the actual value window as the
"Repos" offset.
"REPOS" offsets can be displayed in the machine coordinate system (MCS) or workpiece
coordinate system (WCS).
