Incremental jog positioning
With incremental jog positioning you can move a machine axis by a
preset distance.
Select the Jog Increment mode.
Enter interpolation factor, i.e. 4
Go to JOG INCREMENT.
Enter the jog increment in millimeters, i.e. 8 mm.
The axis moves by the jog increment every time an
external axis-direction button is pressed.
Positioning with manual data input (MDI)
Positioning with manual input of the target coordinates is described in
Chapter 3 (see ”Positioning with Manual Data Input (MDI)” on page
38).
If short-circuit monitoring is active: When the electrode
makes sparking contact, the TNC stops positioning in the
direction of the workpiece, and only permits retracting in
the opposite direction. Also, the axes cannot be switched.
After they have been retracted at least 10 µm, the TNC
switches back to normal Handwheel operation mode.
This function is not active while the reference marks are
being traversed.
The axes can also be positioned with the electronic
handwheel in the PROGRAMMING AND EDITING mode.
You must set machine parameter MP7655=1.
Incremental Jog Positioning must be enabled by the
machine tool builder. Refer to your machine manual.
