• When the next R-position is negative and within the V-die safety this will always give
collision. The control will give a warning and the "start" button will not be accepted.
Figure 4.3.c
Automatic R-axis adjustment
The zero position of the R-axis always corresponds with the position (height) of the upper side
of the die. When the height of the die changes - you have selected a die with another height - the
zero position of the R-axis is automatically adjusted to the height of the new programmed die.
In the machine parameters menu of the R-axis it is also necessary to program the R-axis
reference value (parameter 5, only in case of encoder position measurement). This parameter is
necessary to be able to adjust the R=0 position to the top of the die. The reference value you
have to program is the distance between the R-axis position at the reference pulse (of the
encoder) and the top of the die.
Figure 4.3.d
Besides the zero position adjustment you also have to program in the machine parameters the
maximum and minimum value of the R-axis. These values are related to the absolute R-axis
values. These R-axis values have to be determined without tools. The maximum value of the R-
axis is the mechanical stroke length above the table and the minimum value of the R-axis is the
mechanical stroke length below the table. So the Rmax. and the Rmin. parameter are related to
the top of the table.
The value of the R-axis on the control screen always relates to the top of the die!
