5-4-7 Return to Origin
Return to Origin Mode Description
When using Return to Origin Function, the user can use Digital Input Contact ORG (External
Detector Input Point), CCWL or CWL can be used as Origin Reference Point. The user can also use
ZPulse as Origin Reference Point
. It is also possible to search by selecting Forward or Reverse
Direction; when Return to Origin is completed, Un-55 (System multi-rotation position) and Un-56
(System Single-rotation position) will return to Zero. Refer to the following description for details:
Please set the Pn355 reset to oorigin function operation mode according to the requirement of return to
origin.
● Pn355 = 0: Perform returning to origin function according to Pn317.0, Pn317.1, Pn317.3
● Pn355 = 1 ~ 37: Please refer to [8-3-6-10 Homing Mode (HM)]

After Return to Origin is activated, Motor searches for Origin with first stage Speed in Forward Direction
and uses Digital Input Contact Point CCWL or CWL as Origin Reference Point. After Return to Origin and
positioning are completed, Digital Input Contact CCWL or CWL becomes the Limit Function again. When
using this Function, Pn317.1 cannot be set to 1 or 2. Attention! Cn002.1 (Contact Auxiliary Function - Input
Contact CCWL and CWL Function Selection) must be set to 0.

After Return to Origin is activated, Motor searches for Origin with first stage Speed in Reverse Direction
and uses DigitalInput Contact Point CWL or CCWL as Origin Reference Point. After Return to Origin and
positioning are completed, Digital Input Contact CWL or CCWL becomes the Limit Function again. When
using this Function, Pn317.1 cannot be set to 1 or 2. Attention! Cn002.1 (Contact Auxiliary Function - Input
Contact CCWL and CWL Function Selection) must be set to 0.

After Return to Origin is activated, Motor searches the Origin with first stage Speed in Forward Direction
and uses Digital Input Contact ORG (External Detector Input Point) as Origin Reference Point. If
Pn317.1=2, system will directly search for the top edge closest to Digital Input Contact Point ORG as
Machine Origin without Origin reference point and stop according to the method set in Pn317.3.
