After switching on the control, you approach the reference points for the
individual axes. In this manner, the control is synchronized with the machine
(this does not apply for machines with absolute encoders).
• The machine area has been selected.
• JOG mode has been selected.
• The mode group and channel have been preset.
Note
The machine manufacturer can change the reference point
approach by means of the configuration. In this case, the following description
does not apply.
In JOG mode, "Approach reference point" may be selected by pressing the
appropriate key.
Now press the direction keys on the machine control panel. In the case of the
machine control panel for a milling machine select the axis first.
The control checks the selected direction for traversing before the start:
If the wrong direction key has been pressed (e.g. + instead of -) the operation is
not accepted and no movement takes place.
When the reference point has been approached, this is displayed on the screen
for the appropriate axis.
The control is synchronized with the machine once the reference point has been
approached for all axes.
Using the FEED HOLD key, you can stop the selected axis before the
reference point has been reached.
Machine manufacturer
The position of the reference point and the traversing speed are set by the
machine tool manufacturer by way of machine data.
