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.
force.)
Reference
 When using the zero return function (mode 1 or 2), set P075 (Positioning Mode Selection) to 00 (limit).
Zero Return Mode 1 (P068 = 00)
(1) Accelerate until the zero return mode 1 frequency (speed) according to the acceleration time.
(2) Operate at the zero return mode 1 frequency (speed).
(3) Apply DC injection braking (DB) the moment an ORL signal is input.
