2 Illustration of Encoder Data within Master The IN as well as OUT data of the encoder are assigned 2-word addresses within the master (control). The absolute position of these word addresses depends on the position of the encoder on the Interbus ring. 2.1 Position of the Encoder Data within the 2-word Addresses Please find below the value of the encoder data relating to the relative word address.
3 Possible Modes of Operation Normal Operation Control word: Operation Actual position value not valid D31 0 Set zero offset Specific to manufacturer Parameter No. D30 0 D29 0 Set zero offset Specific to Parameter No. manufacturer D30 0 D29 X D28 1...
Coding of Actual position value The parameter defines the coding of the actual value of the position allotted during OPERATION state.
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.

7 Disturbance messages If there occurred an error when turning power on or during parameterization, the encoder switches to the DISTURBANCE state after the user has passed the device control command ENABLE OPERATION and allots a disturbance number to the bits D25-D28 of the status word. If an error occurs within the encoder during the OPERATION state (e.g.: disturbance number 15), the encoder automatically switches to the DISTURBANCE state. Disturbance No.
