The orientation complete signal (ORA) is
output delaying the set time after in-
position zone is entered. Also, the signal
turns off delaying the set time after in-
position zone is out.

Orientation fault signal (ORM) is output
when the encoder remains stopped for the
set time without orientation completion in
the state where no orientation complete
signal (ORA) is output. ORM signal is
output when orientation is not completed
again in the set time in the state where
ORA signal is output.

is not completed within the set time.

Turning off the start signal with orientation
command (X22) on after stopping the motor
by orientation control, the present position
is checked again after the set time elapses
and the orientation complete signal (ORA)
or orientation fault signal (ORM) is output.
