4 Lifting axes

NOTE

Setup activities require the SITEST program. All the steps described for one tower also apply to

the second tower.

WARNING

All screws locked with red screw locking varnish must be locked again after an adjustment has

been made.

Before carrying out work on the motors of the lifting axes, you must ensure that the lifting axis is

moved to the lowest position so that it can be rested against the buffer. Otherwise the lifting axis

may drop a significant distance when the motor brakes are put out of action.

There is a risk of injury and/or damage to machinery if these instructions are not followed.

Zero offset (zero position)

The zero offset is used to define the refill position of cassette 1. The zero offset is the difference

between the physical home position of the lifting axis and the refill position of cassette 1.

Refill positions (operator removal positions)

At the refill positions of cassettes 1 - 5 (tower 2: cassette 1 - 4), the cassettes can be removed

from the tower by the operator. The relevant cassette is located at the level of the tabletop which

is used as an aid in removal and feeding.

Transfer positions (WTC removal positions)

At the transfer positions of WTCs 1 - 5 (tower 2: WTCs 1 - 4) the lowest WTC in each cassette

can be moved onto the rails of the feed axis by the driver.

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.

Guide rails and stopper bars

The guide rails and stopper bars ensure that operation is only restored after refilling if the

cassettes and WTCs have been inserted correctly. They prevent them from inadvertently straying

out of the locked position during operation.

Cassette guide rails

The cassette guide rails guide cassettes onto the tabletops during refilling.

WARNING

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

positions of these axes.
