5.3.11 Compressed Air Supply to the C&P20A
The 4.8 bar air supply to the C&P20A is needed for the following functions:
Vacuum supply in the holding circuit
Vacuum and air blast supply for the placement circuit (pressure control valve)
Cooling facility for the X axis motor.

Another use of the 4.8 bar compressed air is for
the Z axis safety mode. As long as the machine is
in normal mode, the Z axis can move freely within
its travel range. In the case of power cuts or when
the machine is switched off, a safety mode is
needed since the weight of the Z axis causes it to
fall down and it could be damaged when the gantry
is moved. With the help of the return unit, the Z
axis can be moved to a safe position in just a few
ms. In the event of a fault, like a power cut, the
power fail mode is also activated, which powers
the Z axis for about 200 ms seconds with the aid
of a capacitor, located in the main power supply.
This ensures that the Z axis moves up with the
power provided and with additional help from the
return spring.

5.3.14 Cooling the X Axis Motors
5.3.15 Cooling the Y Axis Motors for Placement Area 1/2
To cool the Y axis motors, an additional pneumatic system is integrated, which sucks the air from the
environment, compresses it in a compressor and conducts its through a hose system to each of the Y
axis motors.
The motor coil temperature is monitored. If this exceeds 110°C, a message will appear on your screen.
This simple cooling system is installed to ensure that the Y axis does not overheat.
5-34: Cooling system X axis motor
The exhaust air from the vacuum generator
(pressure control valve) of the C&P head is used
to cool the X axis motors.
