Type 2
This origin search type returns to the origin using the origin proximity input signal (ORG
signal) and the origin input signal (ZERO signal). The outline of the operation is as follows:
1. The axis travels in the direction specified as origin search direction in the Origin Search
Function Selection (Pn801) at the Origin Search High Speed (Pn802).
2. When the status of the origin proximity input signal changes, the axis decelerates, and
travels at the Origin Search Proximity Speed (Pn803).
3. When the origin input signal changes after the status of the origin proximity input signal
changes again, the axis decelerates further and travels at the Origin Search Compensa-
tion Speed (Pn804).
4. The axis travels the Origin Compensation Value (Pn805) from the position where the
origin input signal status changed, and that position becomes the origin.
