Origin Search Operation
Section 8-2
When using a G5-series or G-series incremental encoder, only the encoder
type setting in the Axis Parameters is required (When using the incremental
encoder, the settings for the Servo Parameter Pn015 (G5 series) and Pn00B
(G series) are disabled).
When using a W-series incremental encoder, only the encoder type setting in
the Axis Parameters is required (the Pn002.2 setting in Servo Parameters is
disabled when an incremental encoder is used).
An absolute encoder cannot be used with a SMARTSTEP Junior Servo Drive,
and Pn002.2 is not supported. Use the Servo Drive as if the axis parameters
are set for an incremental encoder.
Origin Input Signal Parameters

×
14 hex
Use this parameter to select the origin input signal to be used with origin
search. When external latch signals 1 to 3 are used as the origin input signal,
the external latch signal used must be allocated in the Servo Drive's external
input allocations.
When using a SMARTSTEP Junior Servo Drive, only the Z phase or the exter-
nal latch signal 1 input can be set for the origin input signal.
