Checking the load-free alignment of the SSI- & EnDat-encoders
While the rotary encoder calibration is being checked, the ZETADYN 4 energises each individual pole
with direct current. The offset is determined at each pole and the averaged offset is calculated. This
offset can be saved in the ZETADYN 4.
Information
The offset determined during the check is not saved in the ZETADYN 4 because if the frequency
inverter is replaced, the new frequency inverter will not use the same rotary encoder offset. A new
rotary encoder offset must be performed, or the old rotary encoder offset must be entered.
Information
During the rotary encoder offset, the driving disk must turn to the right (when looking at the
driving disk). Once the calibration is complete, the driving disk must be located in the same
position as at the start of the process.
Saving the checking
To save the result, a memory card needs to be in the X-MMC card slot during the check.

Keep the inspection run push-button pressed for approximately 2 minutes.
The offset value check now runs automatically and lasts about 2 minutes.
The rotor now makes a full revolution and the offset value is determined at
every pole.
