The origin search function starts when the origin search start signal turns ON, and establishes the origin
at the point when the origin search limit signal turns ON. The origin search function has two origin
search modes as shown below.
Select one that is suited to your application.
The origin search function does not work when the Position Control Mode Selection (P075) is set to 01
(No limit).
Be sure to set the Position Control Mode Selection (P075) to 00 (Limit).
z Origin search mode 1
Use this mode to establish the origin simply by using sensors.
(1) When the origin search startup signal (C001 to C007 = 70: ORG) turns ON, the
inverter accelerates in the direction set in the Origin Search Direction Selection
(P069) for the set acceleration time. Do not input the RUN command. Doing so acti-
vates the simple position control function.
(2) The inverter operates at the Origin Search Mode 1 Frequency (P070).
(3) When the origin search limit signal (C001 to C007 = 69: ORL) turns ON, the inverter
switches to the DC injection braking mode.
(4) Turn OFF the origin search startup signal (C001 to C007 = 70: ORG). The Current
Position Monitor (d030) is cleared to zero and starts counting the current position
again.
