Origin Search Operations
1,2,3...
2-level Speed in One
Direction Mode
Description
1. When the origin search is executed, the axis is moved in the specified di-
rection at the specified origin search feed rate.
2. When the origin proximity input signal is input, the speed is changed to the
origin search approach speed.
3. After the origin proximity input signal is turned OFF, the speed is reduced
at the first rise of phase-Z.
4. The machine origin will be defined after the axis travels back for the excess
distance at the origin search creep speed.
• If the final travel distance has been specified, the machine origin will
be defined after the axis travels back for the specified distance.
• If the reference origin offset value has been set in the system param-
eter, the specified value will be the machine coordinate of the stopping
position.
• The origin search operation and alarm occurrence will vary depending
on the input timings of limit input signal, origin proximity input signal,
and phase-Z, origin search start direction, and the position of the work
when executing the origin search.
