Range Description
The orientation complete signal (ORA) is
output delaying the set time after in-
0 to 5s 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
0 to 5s
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.
Measure the time taken after passing the
creep switchover position and output the
0 to 60s
orientation fault signal (ORM) if orientation
is not completed within the set time.
9999 Set to 120s.
Turning off the start signal with orientation
command (X22) on after stopping the motor
by orientation control, the present position
0 to 5s
is checked again after the set time elapses
and the orientation complete signal (ORA)
or orientation fault signal (ORM) is output.
9999 Not checked.
Set the number of pulses of the encoder.
0 to 4096 Set the number of pulses before multiplied
by four.
Orientation is executed from the current
0
rotation direction.
Orientation is executed from the forward
1
rotation direction.
Orientation is executed from the reverse
2
rotation direction.
0 to 1000
Servo rigidity is (response level during
position control loop) at orientation stop
can be adjusted.
Lag/advance compensation gain can be
0 to 100.0%
adjusted.
Make adjustment when the motor runs
0 to 1000 back at orientation stop or the orientation
time is long.

0 to 400Hz Set the range of speed feedback control.
9999 Encoder feedback control is invalid
Set when the rotation is unstable or
0 to 100
response is slow.
Set the number of pulses of the encoder.
0 to 4096 Set the number of pulses before multiplied
by four.
When the motor speed reaches or exceeds
the speed set in Pr.374 during encoder
feedback control, real sensorless vector
control, or vector control, over speed
(E.OS) occurs and stops the inverter output.
