Calibration is only possible when no travel job is active!
6 External gear
If an external gear is used, a factor can be programmed via the parameters no. 11 'ü –
numerator' and parameter no. 12 'ü – denominator' in order to include the gear ratio in
position sensing.
Example (see Fig. 7):
The actuator is operated on a gear with transmission reduction of 5:1. For this purpose, the
parameters 'ü-numerator' and 'ü-denominator' must be programmed as follows:
 Parameter 'ü – numerator': 5
 Parameter 'ü – denominator': 1
Fig. 7: External gear
Input of an odd gear transmission reduction value is possible according to the following
example:
Transmission reduction = 3.78
 Parameter 'ü – numerator': 378
 Parameter 'ü – denominator': 100
