Method 33 and Method 34 (Homing on index pulse)
The following figure shows the operation of Homing method 34. The homing direction of Homing method 33 is opposite to that
of Homing method 34.
• When homing is performed from near the Z-phase, the homing completion position varies. The
recommended start position for homing can be found by rotating the servo motor about a half-turn away
from the homing direction.
• When the stroke end is detected
