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.

Travel ranges for X and Y axes (D4/D4i and X4 shown as

example)

The end of the X-axis travel range (software end position)

is 0.5 mm before the hardware end position, which is 1.5

mm before the bumper. A safety distance of 2.0 mm to

the bumper is adequate, if the X-axis moves into this area

with excessive speed.

The end of the Y-axis travel range (software end position)

is 1.5 mm before the hardware end position. The Y-axis

travel range for a particular placement area is monitored

in one direction by the software end position and a bump-

er. In the other direction, the travel range is calculated

from the position of the opposite gantry. A mutual gantry-

gantry position query is issued, which regulates the start

of the Y axes. The communication exchange is via the

SPI bus (Small Processor Interface bus) between the Y

axes and reports their positions and speed (see descrip-

tion of anti-crash function). The safety distance between

the gantry bumpers is 4 mm during placement.

Travel ranges and safety distances for gantry axes (D4/

D4i and X4 shown as example)

1. This means that, during travel range calibration, the

X-axis moves as far as possible towards the mini-

mum or maximum position, until it touches the bump-

er.

The travel ranges are calculated, taking into account

the relevant safety distance.

2. In placement areas 1 and 2 of the D4/D4i, gantry 1/2

moves to the minimum position and gantry 4/3 to the

maximum position, for calculation of the Y-axis travel

range.

3. The safety distance (1) between the sides of the gan-

try facing each other is at least 4mm, during place-

ment.
