(26) Zero Point Return
OW 3C
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.
OW 3D
Set the width to turn ON the Zero Point Position bit in the Position Management Status (monitoring parameter IB
OW 3E
Set the approach speed for a zero point return operation after the deceleration LS is passed.
OW 40
Set the creep speed for a zero point return operation after the ZERO signal is detected.
OW 42
Set the distance from where the signal is detected to the zero point position.
A typical example of a zero point return operation is shown below.
Refer to 8.4 Zero Point Return (ZRET) for details on zero point return.
