■Method -11 and -43 (dogless Z-phase reference homing)
The following figure shows the operation of Homing method -11. The homing direction of Homing method -43 is opposite to
that of Homing method -11.
• 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.
