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.

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.
Elastic mech. Combination (Belt) and light barrier below, for the fast
recognition of the lower position.

– Move the gantry in the Service position, so that the Z-axis move in a free space.
