- After shifting to a Z-phase search, even if the external contact input that activates
the Stop Immediately or Decelerate and Stop operation is detected, the Z-search
operation will continue. (This behavior is different from the origin search in the
F3NC11-0N and F3NC12-0N modules)
- During the origin search, no error occurs even if the axis exceeds the range defined
by the positive and negative direction limit values.

Procedure:
1
.
Write the parameters and command code required for the normal origin search
operation to the positioning module with the WRITE or any other appropriate
instruction (set the command code to 2).
2
.
Set the Execute Command output relay. The Execute Command ACK input relay
will be set, and the automatic origin search starts. Operation continues until the
specified external contact input is detected. If there is an invalid parameter, the Error
Notification Input Relay will be set but not the Execute Command ACK Input Relay.
3
.
When Z-phase pulses are detected for the specified number of times after shifting to
a Z-phase search (if this number is specified as ‘’0," the module skips the Z-phase
search), the current position is specified as “Position 0” and the axis stops
immediately. After outputting the deviation pulse clear signal for a preset duration,
the End of Positioning input relay is set.
4
.
Confirm the status of the origin search by checking the origin search status. If the
origin search status is “0,” the origin search has ended following a successful Z-
phase search. For details on the origin search status, see Section 5.2, “Description
of Statuses”.

Sample Program:
This program starts the origin search using the Request to Search Origin input and stops
the search using a designated external contact input. If any error is detected during the
search, the search status is automatically reset. The program also uses some area for
non-required parameters because all the parameters are written at once. All required
parameters are preset in the data registers.
