NOTE:
Z axis
The Z axis positioning time in the current or force sensor mode does not permit direct
conclusions about the functions. In order to check the function of these modes, please use an
oscilloscope or perform force measurement during placement.
NOTE: D Axis
The positioning times between the left and right turns of the sleeve may deviate from one
another considerably. However, the time characteristic of this axis is not critical for Twin head
operation, due to the placement procedure.

9.6.3 Twin Head Axis Track Signals
The track signals play a greater role with the new drive concept for HF machines. They are responsible
for the exactly and precise positioning of the axes and are used as the only feedback signal in the closed-
loop control system, meaning that they have an important influence on the axis dynamics.
9.6.3.1 Measurement Setup
9-29: Measurement setup for the analog track signals of the Twin head Z axis
The analog track signals of the Twin head Z axes are counted by the incremental encoder.
NOTE:
The digital track signals for the Twin head can only be measured at the axis test box. The track
signals for the Twin head D-axis can only be measured as digital signals at the axis test box.

NOTE:
The zero pulse measured at the axis test box has been reversed to become the zero pulse of
the Schmitt trigger circuit.
