Operation
Origin Search Pattern 3: Starting Between Origin Proximity Signal and CCWL Signal
1. Positioning begins in the origin search direction at the origin search high speed.
2. The direction of movement is reversed when the CCWL signal turns OFF.
3. When the origin proximity signal turns from ON to OFF, the direction of movement is reversed again
and the speed is changed to the origin search low speed.
4. The origin is established by the first Z-phase signal that is received after the origin proximity signal
turns OFF.
