3. Motor revolutions
Unknown gear ratio
If you do not know the gear ratio, then you must measure the ratio, for example by manually
rotating the motor and counting the load revolutions.
Example: After 5 motor revolutions, the load has turned through 37 °. The ratio is therefore
37 ° / (5 × 360 °). You must then enter the following values into Startdrive:
37 [load revolution]
1800 [motor revolution]
4. Check the maximum resolution based on your encoder data.
5. Calculate:
Value = 360 ° / required resolution, e.g. 360 °/ 0.1 ° = 3600.
Enter the calculated value into Startdrive.
You have normalized the encoder signal.

6.2.2 Modulo range setting
Description
Linear axis
A linear axis is an axis whose traversing range is limited in both motor directions of rotation by
the mechanical system of the machine, e.g.:
Stacker crane
Elevating platform
Tilting station
Gate/door drive
