The figure below shows action according to the setting of the d209 parameter. In the figure, it is
assumed that bit 2 = 0 and reverse operation is performed at detection of an overtravel.

: Startup direction of return-to-origin operation 0: Forward rotation direction, 1: Reverse ro-
tation direction
Return-to-origin operation starts in the direction defined by this bit regardless of the direc-
tion specified in the RUN command from the inverter.
: Direction of return-to-origin operation 0: Forward rotation direction, 1: Reverse rotation di-
rection.
This bit defines the direction of movement of the return-to-origin operation. When the re-
verse of the startup direction is set, ORL (origin search limit signal) is detected, then op-
eration is paused and is reversed.
: Return-to-origin operation overtravel operation selection 0: Reversal by overtravel detec-
tion, 1: Stop by overtravel detection
This bit defines whether to stop or reverse operation when an overtravel is detected be-
fore ORL (origin search limit signal) is detected.
: Origin limit switch timing selection 0: ON edge detection, 1: OFF edge detection
This bit defines whether or not to detect the limit switch at its ON edge or OFF edge.
