8-5-6 Origin Return
An origin return operation moves the motor to the origin position from any other position.
The origin return operation is controlled by the ORG(889) instruction.
The origin return operation returns the motor to the origin by starting at the specified speed, accelerat-
ing to the target speed, moving at the target speed, and then decelerating to a stop at the origin posi-
tion.
Set the origin return parameters in the Pulse Output and Origin Search Detailed Settings Dialog Box
that is accessed from the I/O Module Tab Page in the PLC Setup.
z Origin Return Parameters
Note An instruction error will occur if the origin is not defined (i.e., when using a relative coordinate system) when
the ORG(889) instruction is executed to perform an origin return operation.
