Star axis control system
The closed-loop control system for control of the head
axes consists of the following parts. The differences be-
tween the head axes will be explained later in this chap-
ter.
▪ Axis board A364
▪ Servo card
▪ Motor
▪ Measurement system (incremental scale and encod-
er (read unit)

5. 3 phase AC motor.
6. Between the motor and the incremental encoder
there is a fixed mechanical connection.
7. Incremental encoder: transmits the exact position of
the axis. The track signals are the only feedback sig-
nals for the axes.
The servo board controls the motor directly.

Track Signals for Head Axes
The track signals play a greater role with the new drive concept for SIPLACE machines. They are re-
sponsible 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.

Measurement Setup
The head axis track signals can only be measured as digital signals i.e. the analog signals are converted
into digital signals in the read unit.
