6.5.3 Control nozzle changer on the C&P heads
The nozzle changer are controlled via CAN Bus. Depending on the location at the machine the
SLIO at Main- or Sub-Distributor is used. At HF-machine version ’A’ the nozzle changer is control-
led via the "One Wire Bus". Solenoid valves activate the pneumatic rotary drives to open or close
the nozzle changer.

6.6 Axis control
6.6.1 Overview Axis control Star-, Z- and DP-Axis
The closed-loop control system for control of the head axes consists of the following parts. Bet-
ween the head axes, some differences which will be explain later in this chapter.
– Axis controller ’A363’ with VC 3 Controller
– Servo card (SDS)
– Motor
– Measuring system (Incremental- scale and -encoder)
Fig. 6.6 - 1 Excample: Axis control for Star axis
Axis card A363 with VC 3 Controller (VC = Velocity Commutation)
Control signals I
nom "W" and I nom "U"
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-overstep-
ping longer than 2,5 sec.
Servo board control directly the motor.
3 Phase AC 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.
