NOTICE

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.

The placement head is supplied with 5.1 bar compressed air from the pneumatic unit.

D4/D4i/D2/D2i/D1/D1i: The 7-fold pneumatic hose is also used to cool the Y-axis motor. The X-axis mo-

tor is cooled by the traverse fan.

8.4.1 Travel Ranges and Speed Monitoring at the D4/D4i (A364)

Travel Ranges and Speed Monitoring at the D4/D4i (A364)

The travel range of the X- and Y-axes is determined automatically with the SITEST program.

This means that, during travel range calibration, the axis concerned moves stepwise towards the mini-

mum or maximum position, until the set target value is no longer reached by the axis. It is then assumed

that the hardware limit switch (bumper) has been reached. After a time window of approx. 10 ms, the

greatest actual value achieved is taken to calculate the travel range.

To guarantee an appropriate safety distance before the hardware end position is reached, a certain dis-

tance is deducted from the set travel range and is defined as the software end position for the axis. This

enables the axis to brake in time, even when errors occur.
