Reference submode
Switching on the machine and traversing the reference
points can vary depending on the machine tool.
Whether a reference run is necessary or not depends on the
encoders used:
EnDat encoder : Reference run is not necessary
Distance-coded encoder : The position of the axes is
ascertained after a short reference run
Standard encoder
: The axes move to known, machine-based
points. As soon as a reference position is traversed, a signal
is transmitted to the control. The control knows the distance
between the reference position and the machine datum and can
now establish the precise position of the axis
Reference run:
Press the
Z
reference soft key
Press the X reference soft key
Alternative: Press the
All
soft key
Press the NC start key
The control approaches the reference positions.
The control activates the position display and
activates the
main menu
.
In case you traverse the reference marks separately for
the X and Z axes, you only traverse in either the X or the
Z axis.
