( 25 ) Zero Point Return
A typical example of a zero point return operation is shown below.
Refer to 5.2.3 Zero Point Return (ZRET) for details on zero point return.
OW††3C
Home Return Type
Setting Range Setting Unit Default Value
0 to 19 − 0
Set the operation method when the Zero Point Return (ZRET) motion command is executed.
With an incremental encoder, there are 13 different methods that can be used for the zero point return operation. With an
absolute encoder, the axis is returned to the zero point of the machine coordinate system regardless of which method is being
used.

Setting Range Setting Unit Default Value
0 to 65535 Reference unit 100
Set the width to turn ON the Zero Point Position bit in the Position Management Status (monitoring parameter IB††0C4).
OL††3E
Approach Speed
Setting Range Setting Unit Default Value
−2 31 to 2 31 −1 Depends on Speed Units. 1000
Set the approach speed for a zero point return operation after the deceleration LS is passed.
OL††40
Creep Speed
Setting Range Setting Unit Default Value
−2 31 to 2 31 −1 Depends on Speed Units. 500
Set the creep speed for a zero point return operation after the ZERO signal is detected.
OL††42
Home Offset
Setting Range Setting Unit Default Value
−2 31 to 2 31 −1 Reference unit 0
Set the distance from where the signal is detected to the zero point position.
