Siemens SINUMERIK 840D sl Turning - Modes and mode groups

4.3 Modes and mode groups
4.3.1 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
● Traverse axes, e.g. during a program interrupt
● Positioning axes
Select "JOG"
Press the <JOG> key.
The following functions are available in "JOG" mode:
● "REF POINT"
● "REPOS"
"REF POINT" function
The "REF POINT" function 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" function
The "REPOS" function is used for repositioning to a defined position. After a program interrupt
(e.g. to correct tool wear values), move the tool away from the contour in "JOG" mode.
The path differences 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).
