Origin
Search
Origin Search
Setting
Select whether to use the origin search function.
Disable The origin search function is not used.
Enable The origin search function is used.
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 mov-
ing in the origin search direction.
CW Performs origin search in the clockwise direction.
CCW Performs origin search in the counterclockwise direction.
Origin
Detected after
Prox Input
Set one of the following three methods to determine the pattern to use for the origin proximity
input signal.
0: Turns ON and then
OFF
The origin input signal is accepted after the origin proximity input signal
turns ON and then OFF.
1: Turns ON The origin input signal is accepted after the origin proximity input signal
turns ON.
2: Proximity Input Not
Used
The origin input signal is accepted without using the origin proximity
input signal.
Only the origin search initial speed and origin search proximity speed
are used for the origin search speeds.
Origin Search
at Limit Input
Select one of the following two modes for the origin search operation pattern.
0: Reverse The direction is reversed when the limit input signal is received while
moving in the origin search direction.
1: Stop with Error An error occurs and operation is stopped if the limit input signal is
received while moving in the origin search direction.
Operation
Mode
This parameter determines if a stepping motor or a Servomotor is used.
Set whether to use positioning completed input signals when using a Servomotor.
Mode 0: Stepping
Motor
Error counter reset output: Not used.
Positioning completed input: Not used.
Mode 1: Servomotor Error counter reset output: Used.
Positioning completed input: Not used.
Mode 2: Servomotor
with INP
Error counter reset output: Used.
Positioning completed input: Used.
Origin Input
Signal Type
Specifies the type of origin input signal (NC or NO).
NC (Normally Closed) Sets a normally closed origin input signal.
NO (Normally Open) Sets a normally open origin input signal.
Proximity
Input Signal
Type
Specifies the type of origin proximity input signal (NC or NO).
NC (Normally Closed) Sets a normally closed origin proximity input signal.
NO (Normally Open) Sets a normally open origin proximity input signal.
High Speed
(pps)
Sets the motor's target speed when the origin search is executed. Specify the speed in the num-
ber of pulses per second (pps).
Setting range: 0 to 100 kpps
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.
