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)

1. Axis board A364
2. Control signals I target "W" and I target "U"
3. Servo amplifier
4. LEDs on 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. The track signals are the only feedback sig-
nals for the axes.
The servo board controls the motor directly.
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
