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’ and SIPLACE X the nozzle
changer is controlled 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.
