Zero Return Function - Omron 3G3MX2 User Manual

Zero Return Function

This function performs two types of zero return operations according to Zero Return Mode
(P068).
Zero return starts when the Zero return start signal (70: ORG) turns ON. When zero return is
complete, the current position is cleared (= 0).
Select the zero return direction in Zero Return Direction Selection (P069).
If zero return is not performed, the Inverter performs position control with the position at power-
on defined as the origin.
