8.5.5 Pneumatic plan for nozzle changer
Fig. 8.5 - 4 Pressure air supply for the nozzle changer
The air pressure supply of the nozzle changer will be assembled by the T-piece as shown in the
picture below. A additional Y- piece is necessary for the optional 2
nd
Nozzle changer carrier.
Fig. 8.5 - 5 Air pressure connection of the nozzle changer
The DLM nozzle changers are connected to 2.5 bar (loopedhose in the picture). The C&P20 noz-
zelchanger is connected to 4.5 bar.

6.3 Axis control C&P 20
6.3.1 Overview Axis control Star-, Z- and DP-Axes
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 card with VC 3 Controller (on free axis the VC 3 controller may are missing)
– Servo card (SDS)
– Motor
– Measuring system (Incremental- scale and -encoder)
Fig. 6.3 - 1 Example: Axis control 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.
