Origin Search Operation
Section 6-4
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
direction 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 chattering.
When origin search is executed, the operation will differ according to whether
or not origin proximity signal is used in the way shown below.
With an Origin Proximity
Input Signal
There is no deceleration when stopping from the origin search proximity
speed with the origin input signal.
Without an Origin
Proximity 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.
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.
During origin search, the origin input signal in the direction of the origin search
direction is always being detected.
0: CW direction, 1: CCW direction

The origin proximity input
signal is not used.
Origin search is per-

search proximity
speed only. (Refer to
the following dia-

Only possible in sin-

executed in reverse
modes 1 or 2, an ori-
gin detection method
error (error code
1607) is generated
and settings are not
possible.
