The machine is synchronized as soon as the reference point is
reached. The actual value display is set to the reference point value.
The display is the difference between the machine zero and the slide
reference point. From now on path limits, such as software limit
switches, are active.
End the function via the machine control panel by selecting operating
mode "Machine Auto" or "Machine Manual".
• You can reference all axes simultaneously (depending on the PLC
program supplied by the machine tool manufacturer).
• The feedrate override is operative.
The machine manufacturer can define the order in which the axes will
be referenced.
Only when all axes with a defined reference point have reached this
point will you be able to start with the "Cycle Start" key in "Machine
Auto".
