The values for the three parameters .3.4./.3.5./.3.6. must be determi-
ned using the table in chapter 6.
The mechanical ratio is specified in parameter ".3.7. mech. gear fac-
tor".
The ratio may be established as follows:
Measure distance S 1 between the center of rotation and DC actua-
tor drive securing point. Equally, measure distance S 2 between the
center of rotation and the outfeed point. These two values are set in
relation to one another and the value calculated produces the me-
chanical ratio (parameter .3.7.).
Example:
measured distance S 1
450 mm
measured distance S 2
850 mm
850 mm / 450 mm = 1.89
In this example the entry in parameter .3.7. is 1.89.
During the initialisation run (parameter ..3. / Wert 10) parameter
".3.7. mech. gearfactor" is established automatically.
