11.3.1.2 Terms of calibration feed axes

Zero offset (zero position)

The zero offset is used to define the removal position of WTC 1. The zero offset is the difference

between the physical home position of the feed axis and the position of the driver at which it is

inserted in the WTC on level 1.

Removal positions (WTC removal positions)

At the removal positions of WTCs 1 - 5 (tower 2: WTCs 1 - 4), the driver can be inserted into the

lowest WTC in each cassette and move this into the transfer position.

Transfer position (component transfer position)

The transfer position is the position of the feed axis at which components can be picked up by the

placement head of the SIPLACE station without a correction value. The position of the reference

edges of a waffle pack tray in relation to the reference holes of the MTC 2 is stored in the line

computer.

End positions (min. and max. position)

The end positions of an axis are reached when contact is made with the relevant limit switch.

The value determined here is used as a safety constraint when values are entered in the service

menu of the controller software. If a limit switch is overrun during operation, the relevant axis is

stopped immediately to prevent a crash from occurring.

Handle sensor, WTC safety query and crash light barriers

The handle sensor checks the handle of the WTC in the removal position and thus the position of

the WTC which has been moved back, to prevent a crash from occurring.

The WTC safety query checks the correct position of the WTC which has been moved back before

the lifting axis is moved, to prevent a crash from occurring.

Depending on the height of the waffle pack tray which has been set up, the crash light barriers

check the height of the WTC which is moving back, to prevent a crash from occurring in the

cassette.

Disengaging mechanism

The disengaging mechanism enables the driver to engage with and disengage from the WTC.

WARNING

Incorrectly set machine data can result in a crash between the lifting and feed axes or at the limit

positions of these axes.

NOTE

For the calibration the zero point correction and transfer position at the feed axis please look to

the following notes on the next pages.

Axis

Feed axis

The selected functions are

executed for the feed axis.

Lifting axis

The selected functions are

executed for the lifting axis.

Tower

1/2

Activates the functions

for tower 1 or tower 2.

Info

Current position:

Shows the current position of the activated axis in µm.

Update position

Updates the display for the position of the activated axis.

Travel range

Limit switch +

Moves the selected axis to the limit

switch in order to re-determine the

maximum position which can be

reached. A reference run is then

performed with the axis.

Limit switch -

Moves the selected axis to the limit

switch in order to re-determine the

minimum position which can be

reached. A reference run is then

performed with the axis.

Opens the Teach zero point dialog box

where you can correct the zero point and

then transfers this information.

Every time the button is clicked, the lifting

axis is moved vertically one step downwards

using the increment that you have selected.

Step

Select the desired step size with which to move the

lifting axis.

Current position

Pos.

Displays the position to which the lifting axis moved

during the teaching process.

Apply

Closes this dialog box and accepts the current

position. A reference run is then started.

Every time the button is clicked, the lifting

axis is moved one step upwards using the

increment that you have selected.

Opens the Teach transfer position

dialog box where you can select the

cassette for which the transfer position

is to be taught.

Select the cassette for which the

transfer position is to be taught.

Transfers the selection and opens the

Teach transfer position dialog box.

Open WPTC lock

To check whether the transfer position has been set correctly, the

waffle pack tray carrier is unlocked. It is now possible to push the

waffle pack tray carrier onto the slide rail.

Opens the Teach refill position dialog box

where you can select the cassette for which

the refill position is to be taught.

Select the cassette for which the

refill position is to be taught.

Transfers the data and opens the

Teach refill position dialog box.

11.3.2.2 Feed axes

Notes for calibration the zeropoint correction and transfer position into the machine. 11

1a. Calibration of zero point correction: 11

➠ Carry out the relevant preparatory measures (see section 5.2.2 "Preparatory measures").

➠ Select SITEST --> MTC --> Settings

➠ Press the button "Teach zero point"

➠ Check the position of the driver with the button "ENGAGE". In case the driver did not engaged

successfully you must determine the middle of the notch of the waffel pack tray.

The accurate adjustment is described below:

➠ Determine the minimum position of the notch Fig. 11.3 - 3.

Fig. 11.3 - 3 Minimum position

➠ Determine the maximum position of the notch Fig. 11.3 - 4. at which the driver just engages no

more.
