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 card A363 with VC3 controller or A364
▪ Servo card (SDS)
▪ Motor
▪ Measurement system (incremental scale and encod-
er (read unit)
1. Axis controller board A363 with VC3 controller (VC =
Velocity Commutation)
2. Control signals I target "W" and I target "U"
3. LEDs on servo amplifier:
4. Servo amplifier
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 to the axis card. (The track signals are the
only feedback signals for the axes).
The servo board controls the motor directly.

5.2.3.2 Track Signals for Head Axes
Track Signals for Head Axes
The track signals play a greater role with the new drive concept for HF machines. They are responsible
for the 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.
Overview
Oscilloscope settings
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.
Axis Mode/range Positioning time
Star Axis continuous run / 1 star step 70 ms +/-3 ms
Z Absolute, free space / 685 digits 30 +/-3 ms
Z Light barrier, into calibration tool pocket / approx. 685 digits 30 +/-3 ms
DP 200 digits 38 ms +/-3 ms
DP 7200 digits 85 ms +/-3 ms
