The encoder is aligned manually by rotating it in the motor mating seat. Use the "Position
display" function to position the encoder.
2. Alignment of the encoder position via datum shift
Click the "Datum shift" button to program the datum at the current angular position.
When you click the "Cancel datum shift" button the active datum shift is deleted and the
encoder datum reset to the HEIDENHAIN factory default setting.
Note
Depending on the software configuration (product key required) buttons may be inactive!
If the ECI/EQI encoder does not support datum-shift programming (older encoder models), the
message "Datum shift" is generated.
Press "Write protection" to protect the datum shift from being overwritten.
Note
Once write-protection has been activated (by clicking the "Yes" button in the message
window), it can only be rescinded by HEIDENHAIN.
