Adjustment Instructions MTC 2 4 Lifting axes

12/2007 Edition 4.1 Belt tension

4.1.3 Checking and setting the belt tension

Fig. 4.1 - 2 Setting the belt tension

Key

1. Servo motor of the lifting axis (shown here for tower 2)

2. Dual toothed belt (shown here for tower 2)

3. Mounting plate with clamping screws (shown here for tower 2)

4. Adjusting screws with lock nuts (shown here for tower 2)

Å Carry out the relevant preparatory measures (see section 4.1.2 "Preparatory measures").

Å Measure the belt tension with the belt frequency measuring device in the following way:

Find the holes for the measurement head of the belt frequency measuring device on the lifting

axis. Two holes are provided for each of the dual toothed belts.

Attach the toothed belt tension stickers (item no. 00370691-0) onto the belts in this area.

Å Cause the belts to oscillate and measure their frequency

Å Set the belt tension if the measured frequency deviation deviates from the nominal value..

4.1 Belt tension 12/2007 Edition

 Turn the adjusting screws as far as they will go. Before doing this you will need to loosen

the lock nuts.

 Loosen the four lock screws on the mounting plate of the motor.

 Use the two adjusting screws to raise the belt tension (by turning in a clockwise direction)

or lower it (by turning in an anticlockwise direction), until the nominal frequency is achieved.

Tighten the lock nuts each time you measure the belt tension.

 Firmly tighten the clamping screws and varnish them with red screw locking varnish.

 Check the belt tension again.

 Remove the belt tension stickers.

 Dock the MTC 2 onto the SIPLACE station (see the User Manual).

 Check the zero offset of the lifting axis (see section 4.2.2 "Checking the zero offset") if you

have changed the belt tension.

12/2007 Edition 4.2 Zero offset, refill position and transfer position

4.2 Zero offset, refill position and transfer position

NOTE

You must carry out the steps described for checking and calibrating the refill positions

for cassettes 2 - 5, on tower 1 and

for cassettes 2 -4, on tower 2.

The refill position for cassette 1 corresponds to the zero position (zero offset).

You must carry out the steps described for checking and calibrating the transfer positions

for cassettes 1 - 5, on tower 1 and

for cassettes 1 -4, on tower 2.

NOTE

Always close the tower locking mechanism and the protective door before moving the lifting axis.

4.2.1 Preparatory measures

NOTE

The positions must be checked and calibrated with all cassettes in the towers. There must be a

WTC in each cassette of each level.

 Set the MTC 2 up completely with all empty cassettes (see the User Manual).

 Set up each cassette with an empty WTC.
