If the ORG signal at the start point is triggered (high, Start point 3), the servo reverses with
low speed (second speed setting) and after the ORG signal switches to low, it continues to
look for the Z pulse. Once the servo finds the Z pulse, it decelerates to a stop, completing
the homing procedure.
(b)
If you set the servo to look for the Z pulse in the forward direction or not to look for the
Z pulse (this is similar to method (a) mentioned above), refer to the timing diagram above.
3.
Referencing the Z pulse.
This method uses the Z pulse as the reference origin. One Z pulse is generated per
rotation of the motor. This method is only suitable when the operation is kept within one
motor rotation.
