Preset function
The preset function supports adjustment of the encoder zero point to the system’s mechanical zero point.
The actual encoder position is set to the preset value. The internal offset value is calculated and stored in the
encoder. For storage into the non-volatile memory first the service “save” has to be carried out.
Attention: It is recommended to apply the preset function only in idle status of the encoder.
