6.6.3.4 Example for dynamic with the control signal of the Vnom. output
The Axis dynamic of the Star axis is checked with Star step continuos run. At Vnominal output of
the Axis tester pass a motor current signal. (Control signal1) The uncommutated nominal current
signal (Signal 3) show the friction of the axis system it show also increased friction.
The positioning time for the Star axis step is 70 ms (6 segment C&P head) and for the 12 segments
C&P head 46 +/-3 ms.

6.6.4 Axis control Z-Axis
The Z-axis is driven with a DC servo motor. The control of the axis occurred with one control si-
gnals of the VC3 controller I
nom "W" and I nom "U" = 0. The intermediate circuit voltages is
approx. 60V.
Fig. 6.6 - 10 Axis control Z-Axis
6.6.4.1 Check the dynamic Z-Axis
6.6.4.2 Test setup
Please Note:
The test setup for the Z-Axis is the same as the Star-Axis
The positioning time for the Z-Axis is 30ms +/-3ms (6 segment C&P head) and 24ms, -1 ms of the
12 segment C&P head.
Axis controller ’A363’ with VC 3 Controller (VC = Velocity Commutation)

LED‘s on the Servo amplifier:
– Power supply ON
– Servo enable, if the the enable signal from the axis board available.
– Display R.M.S. current limiter shorter than 2,5 s.
– Error: Overvoltage, -current, -temperature or Nominal current-over-
stepping longer than 2,5 sec.
Servo board control directly the DC motor.
DC motor.
Between the motor and the incremental encoder exist a fixed mechanical
combination.
Incremental encoder: transmit the exact position of the axis via the track
signals.
