15.2.3 Checking the load-free alignment of the SSI- & EnDat-encoders
When checking the encoder offset, the frequency inverter supplies each individual pole in the motor
with direct current. The offset is determined on each pole and the average offset is calculated from
that. This offset can be stored in the frequency inverter.
Information
The offset determined during the inspection is not stored in the frequency inverter because if the
inverter is replaced, the new inverter will not have the identical encoder offset. You must carry out a
new encoder offset alignment or enter the old encoder offset.
Information
During the encoder offset alignment, the driving disk must turn to the right (when looking at
the driving disk). Once the alignment 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.
