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
API
NPV
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
API
NPV
O
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.
