6.1.3 Pneumatic Connections on the Gantry
The placement head is supplied with 4.5 bar compressed air from the pneumatic unit. The 7-fold
pneumatic hose is also used to cool the Y-axis motor. The X-axis motor is cooled by the traverse fan.

NOTE:
eSW axis controller
All zero pulses for the gantry axes are checked to see whether 50,000 count pulses occur or
whether a whole number multiple of this occurs!!
An overshoot check for gantry axis positioning is no longer required. The continual calculation
of the axis positioning, based on the axis track signals, gives optimal positioning, even in the
case of mechanical defects.
Travel range: axis controller determines hardware position at stopper; 2 mm before; travel range
– software position – 0.5 (X) 1.5 mm (Y) before that - limited.
