Range Description
0 Speed command
Position command
16 bit data is used as
1
external position com-
mand as is.
Set the stop position
dividing up to 128
2 to 127
stop positions at reg-
ular intervals.
Shift the origin using a compensation value
without changing the origin of the encoder.
0 to 16383 The stop position is a position obtained by
adding the setting value of Pr. 361 to the
position command.
When servo torque function is selected
using Pr.358, output frequency for
generating servo torque increases to the
0.1 to 10 creep speed of Pr.352 gradually according
to the slope set in Pr.362. Although the
operation becomes faster when the value
is increased, a machine may hunt, etc.
The orientation complete signal (ORA) is
output delaying the set time after in-posi-
0 to 5s tion 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 out-
put 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.

When 1 is set in
Pr.350 and the
option FR-A7AX is
mounted, set a stop
position using 16-
bit data.
Stop position com-
mand is input as
binary regardless of
the Pr.304 setting.
