5.3.2 Origin Search Parameters

This section provides origin search types and their parameter details.
Origin Search Types
The following seven types of origin search are supported.
Type 0
This origin search type returns to the origin using the origin proximity input signal (ORG
signal) and the phase Z pulse of the encoder. The outline of the operation is as follows:
1. The axis travels in the direction specified as the 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. After the status of the origin proximity input signal changes again, the axis decelerates
further when the first encoder phase Z pulse is detected and then travels at the Origin
Search Compensation Speed (Pn804).
4. The axis travels the Origin Compensation Value (Pn805) from the position where the
phase Z was detected, and that position becomes the origin.
