Please Note: (Z-Axis)
The positioning time for the Z-axis with the current mode and force sensor have no direct inference
to the function.
In order to check this functions please use an oscilloscope and for the mode force sensor a special
PCB board with force sensor. 7
Please Note: (D-Axis)
The positioning time for the left and right rotation of the D-axis could be a little bit different, but this
time is not critical in case of the placement sequence of the TWIN- head. 7

7.6.2 Track signals head axes
The track signals undertake the main control function in the case of the new drive concept of the
HF machine. They are responsible for the exact and precise positioning of the axes and are used
as only response of the closed-loop control system so that the track signals have an important
influence on dynamics of the axes.
7.6.2.1 Test set up
Fig. 7.6 - 2 General test set up to check the analoge track signals TWIN- Z-axis
The analoge track signals of the TWIN- head Z-axes are measurable on the incremental encoder.
Please Note:
The digital track signals of the TWIN- head can only be measured on the axis test box.
The track signals of theTWIN head D-axes can only be measured as digital signals on the axis
test box. 7
