Origin Search Operation
Section 6-4
6-3-4
Allocation of Operating Data Areas (Supported for Unit Version
2.3 or Later)
To set the position where the origin search is completed to a desired position,
enable the origin search preset function (e.g., bit 13 in word m+5 for the X
axis) and set the position data.

Origin Search Operation

Operation Pattern Settings for Origin Search
Operation patterns when determining the origin using origin search are deter-
mined by the settings of 5 of the parameters described in
6-3 Data Settings
Required for Origin Search
.
1,2,3...
1.
Operation mode:
• Set the optimum operation mode for the driver (servomotor, stepping
motor) used.
• Set to mode 0 for a stepping motor and set to modes 1, 2, or 3 for a
Servo Drive. (See note.)
2.
Mode for origin search operation:
Set the movement of the motor during origin search.
3.
Origin detection method:
Set the method used for detecting the origin.
4.
Origin search direction:
Set the direction for origin search.
5.
Origin compensation data:
If fine adjustment is required after the origin has been determined (e.g., if
there is inaccuracy in the position at which the proximity sensor turns ON
or if the motor has been changed), set the amount of compensation (the
origin compensation value) required.
Note
There are drivers for stepping motors that can output positioning
completed signals in the same way as Servo Drives. It is possible
to set modes 1 or 2 if this kind of driver is used.

Details of Parameters
The settings for the 5 parameters that determine the operation pattern for ori-
gin search are given here. For data configurations for each of the parameters,
