External interrupt processing is determined by pins 6 and 7 in combination
with bit 06 of IR word n (n = 100 + 10 x unit number). See
Section 4–10 for
details.
This pin selects whether the origin is detected after the origin proximity signal
has turned ON or after it has turned ON once and then OFF.
When the pin is set to ON, origin proximity reverse is enabled. You can use
this function to make sure that a sufficient deceleration period elapses when
there are multiple origin signals. Set the origin proximity signal such that it
remains on longer than the deceleration period. In the following example dia-
gram, ORIGIN SEARCH is executed in the counterclockwise direction.

When the pin is set to OFF, origin proximity reverse is disabled and the origin
signal is detected after the origin proximity signal has turned ON. Note, how-
ever, that the origin signal is not detected in modes 1, 2, and 3 during decel-
eration, and that the origin adjustment signal is not output in mode 3 during
deceleration. Make sure, therefore, that deceleration is completed by the
time the first origin signal is output after the origin proximity signal is turned
on.
