Description
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 performed for the Zero Point Return operation.
Refer to 7.2.3 Zero Point Return (ZRET) on page 7-16 for information on each method.
With an absolute encoder, the axis is returned to the zero point of the machine coordinate system regardless of which
method is being used.
