Origin Search Function

In the Origin Search Mode (P068), select one of the three origin search modes. When origin search is
completed, a new origin is established with the Current Position Monitor (d030) cleared (= 0).
Allocate one of the Multi-function Input S1 to S8 Selection (C001 to C008) to 54 (SON: Servo ON) and
turn ON that terminal SON. Then, start the origin search operation.
Set the origin search direction in the Origin Search Direction Selection (P069).
Unless you perform origin search operation, the position in which the power supply is turned ON will be
used as the origin for position control.
Parameter No.
