Settings Undefined
Origin Hold When a Limit Input Signal is input, the pulse output is stopped
and the previous status is held.
Undefined When a Limit Input Signal is input, the pulse output is stopped
and origin becomes undefined.
Limit Input
Signal Opera-
tion Search Only The CW/CCW Limit Input Signal is used for origin searches only.
Always The CW/CCW Limit Input Signal is used by functions other than
origin search.
Limit Input
Signal NC Select when using NC contact (b contact) for the Limit Input Sig-
nal.
NO Select when using NO contact (a contact) for the Limit Input Sig-
nal.
Search/
Return
Initial Speed Set the motor ’ s starting speed when performing an origin search or origin return.
Specified in units of pulses per second (pps).
Setting range: 0 to 100k pps
The origin search will not be performed in these cases:
Origin search high speed
≤
Origin search proximity speed.
Origin search proximity speed
≤
Origin search initial speed.

tion
Settings Use define
origin opera-
tion Select this check box to use origin searches.
Search Direc-
tion Set the direction for detecting the Origin Input Signal. An origin search is performed so
that the Origin Input Signal
’ s rising edge is detected when moving in the origin search
direction.
CW
Performs origin search in the clockwise direction.
CCW Performs origin search in the counterclockwise direction.
Detection
Method Set one of the following three methods to determine the parameters related to the
Origin Proximity Input Signal.
Method 0
The direction is reversed at the Origin Proximity Input Signal. The
Origin Input Signal is accepted after the Origin Proximity Input
Signal turns ON and then OFF.
Method 1 The direction is not reversed at the Origin Proximity Input
Signal.
The Origin Input Signal is accepted after the Origin Proximity
Input Signal turns ON.
Method 2 The Origin Proximity Input Signal is not used.
The Origin Input Signal is accepted without using the Origin Prox-
imity Input Signal.
Only origin search proximity speed can be the origin search
speed.
Search
Operation Select one of the following two modes for the origin search operation pattern.
Inverse 1
The direction is reversed when the Limit Input Signal is received
while moving in the origin search direction.
Inverse 2 An error is generated and operation is stopped if the Limit Input
Signal is received while moving in the origin search direction.
Operation
Mode This parameter determines the I/O signals that are used for origin search.
Mode 0
Use when connecting to a stepping motor that does not have a
Positioning Completed Signal.
Mode 1 In this mode, the Positioning Completed Signal from the Servo
Drive is not used. Use this mode when you want to reduce the
processing time.
Mode 2 In this mode, the Positioning Completed Signal from the Servo
Drive is used. Use this mode when you want high
positioning accuracy.
Origin Input
Signal Specifies the type of Origin Input Signal (NC or NO).
NC
Sets a normally closed (b contact) Origin Input Signal.
NO Sets a normally open (a contact) Origin Input Signal.
Proximity
Input Signal Specifies the type of Origin Proximity Input Signal (NC or NO).
NC
Sets a normally closed (b contact) Origin Proximity Input Signal.
NO Sets a normally open (a contact) Origin Proximity Input Signal.
