2. Track B
NOTICE!
The pulse width is dependent on the speed, the phase lo-
cation is dependent on the direction.

Star axis control system
The star axis is driven via a 3-phase AC stepping motor
with an intermediate circuit voltage of 120 V. The activa-
tion is via two track signals (phase shift 120°) from the
VC3 controller Itarget "W" and I-target "U". The third
phase is calculated automatically.
1. Axis controller board A363 with VC3 controller (VC =
Velocity Commutation) or A 364
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.
NOTICE
Setting the axes
Before adjusting the axes, make sure that the machine has reached its operating temperature.
Switch the machine on at least 30 minutes before you begin work.
