Zero Offset 
The parameter Zero Offset refers to the difference between the zero point of the installation and the zero point of the 
encoder. The actual position value is calculated according to the following formula: 
PI = API + NPV
The abbreviations stand for: 
 
PI
Actual position value (is transferred)
API
Absolute actual value of position
NPV
Zero set off
 
Offset 
The parameter 'Offset' is an additional possibility to offset the actual position value. 
The actual position value is calculated according to the following formula: 
PI = API + NPV + O
The abbreviations stand for: 
 
PI
Actual position value (is transferred)
API
Absolute actual value of position
NPV
Zero
offset
 O Offset 
 
Resetting Encoder 
When the parameter 'Reset Encoder' is transmitted to the encoder, all parameters are set back to their factory setting. 
 
Measuring Range 
It is possible to adjust the entire range of the position value via the parameter 'Measuring Range’. The unit for the 
measuring range is the number of revolutions. If, for example, a resolution of 200 steps per revolution and a 
measuring range of 5 revolutions are chosen, there ensues a total range of: 
 
 
Total range = Resolution * Measuring range = 200 * 5 = 1000 steps
 
The total range of the position value thus stretches in the process data output without plus/minus signs from 0..999 
and in the process data output with plus/minus signs from -500..499.
