[Procedure 2] Correcting the position of encoder Z-phase
If the cutout groove in the shaft is outside the allowable angle range, make correction by following the procedure
below:
[1] Use a spanner wrench to hold the width across flats on the clasp at the end to keep it in position, and loosen
the lock nut slightly.
[2] Move the clasp at the end slightly in the rotating direction to correct the position.
x If the cutout groove in the shaft is deviated in the A (NG) direction:
Turn the clasp at the end in clockwise direction by using the amount of displacement T1 as a rough guide
(when viewed from the front).
x If the cutout groove in the shaft is deviated in the B (NG) direction:
Turn the clasp at the end in clockwise direction by using the amount of displacement T2 as a rough guide
(when viewed from the front).
[3] After the correction, tighten the lock nut with the clasp at the end still held in position.
[Procedure 3] Confirming the Z-phase position again
Finally, repeat [Procedure 1] to confirm the position of Z-phase again.
If there is no longer displacement or error, the correction has been successful.
