Origin proximity
input signal not
used
The origin
proximity input
signal is not used.
Origin search is
performed at origin
search proximity
speed only. (Refer
to the following
diagrams.)

to origin search
direction.
Only possible in
single-direction
mode. If executed
in reversal modes
1 or 2, an origin
detection method
error (error code
1607) is generated
and settings are
not possible.
Note
Use a sensor with no chattering, such as a photoelectric sensor, for the origin
proximity input signal when the origin detection method is set to 0 (with origin
proximity input signal reversal) and for the limit signal input in the opposite direc-
tion to the origin search direction when the origin detection method is set to 3
(limit input signal used instead of origin proximity input signal). Using a switch
with contacts may cause the position of the origin to be displaced due to chatter-
ing.
When origin search is executed, the operation will differ according to whether or
not origin proximity signal is used in the way shown below.
There is no deceleration when stopping from the origin search proximity speed
with the origin input signal.

The origin search is conducted at low speed (the origin search proximity speed).
There is no deceleration when stopping with the origin input signal.

Initial speed
If the origin search proximity speed is less than or equal to the initial speed, there
will be no acceleration.
Origin Search Direction
This setting determines the direction when detecting the origin input signal. Dur-
ing origin search, the origin input signal in the direction of the origin search direc-
tion is always being detected.
