Origin Search Patterns

This section provides basic examples of origin search patterns with the Origin

Search Method set to Reverse mode or One Direction mode. Operation will vary

depending on the position of the workpiece when the origin search is executed.

7-4-1 Basic Origin Search Pattern

These origin searches are performed with an origin proximity switch and the ini-

tial search direction set to CW. Operation will vary and errors might occur with

different limit switch, origin proximity switch, and Z-phase input timing. Refer to

Appendix B Additional Origin Search Patterns

for more examples.

Description

There are three steps involved in this origin search.

1, 2, 3...

1. When the origin search is executed, the axis is moved in the specified direc-

tion at the origin search high-speed feed rate.

2. When the origin proximity switch input is received, the search speed is

reduced to the origin search low-speed feed rate.

3. After the origin proximity switch input goes OFF, the machine origin is fixed

at the position where the Z-phase signal goes ON. The control voltage drops

to zero at this point.
The axis is then moved by the Reference Origin Offset amount with PTP

control and the resulting position is fixed as the reference origin.
