2. You do not yet know the relationship. If this is the case, the Assistant will help you with
the calculation. Proceed as described below:
• Enter the ratio of the gear unit installed on the motor. Enter as precise a value as
possible to prevent rounding errors. You will find the precise ratios in the catalogs for
STÖBER ANTRIEBSTECHNIK GmbH+Co. KG gear units.
• You can parameterize another ratio in the boxes n3 and n4 (ratio of the speeds), Z3
and Z4 (ratio of the numbers of teeth) or D3 and D4 (ratio of the diameters). If there
are no further ratios in addition to the gear unit on the motor, enter the ratio as 1:1 in
the boxes.
• The last step is the conversion of the speed after the last ratio in user units has been
entered. Enter the format length in mm (e.g., format length of a bottle). Then
parameterize either D4 or the feed constant Cv (feed length per revolution of the
driven gear).
• Press the button “Calculate” (Berechnen). You will then find the results in D87 und
D88.

Setting the relationship of
master/slave drive
Click the “Ratio of the master/slave drive” (Verhältnis Leit- / Folgeantrieb) button to
access page 2.4.1 (Figure 4-11). This page makes it easier to parameterize a 1:1
coupling when the master reference value is connected with an analog input. Proceed as
shown below:
• Using a test for the speed of the master, determine the related voltage which the
reference value supplies to the slave.
• Enter this value in the first line of page 2.4.1.
• Select an analog input in the parameter D140.
• Click the box “Calculate” (Berechnen).
The analog input factor is calculated so that master and slave travel at the same speed
(1:1 coupling).
