position com-
mand as is.
0
Set the stop posi-
tion dividing up
2 to 127 to 128 stop posi-
tions at regular
intervals.
Shift the origin using a compensation
value without changing the origin of
the encoder.

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 creep speed of Pr. 352 gradually
1 0.1 to 100
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 is out-
put delaying the set time after in-posi-
0.5s 0 to 5.0s tion zone is entered. Also, the signal
turns off delaying the set time after in-
position zone is out.
Orientation fault signal (ORM) is out-
put when the encoder remains stopped
for the set time without orientation
completion in the state where no orien-
0.5s 0 to 5.0s tation 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 out-
put.
Measure the time taken after passing
the creep switchover position and out-
0 to 60.0s put the orientation fault signal (ORM) if
9999
orientation is not completed within the
set time.
9999 Set to 120s.
Turning off the start signal with orien-
tation command (X22) on after stop-
ping the motor by orientation control,
0 to 5.0s the present position is checked again
9999
after the set time elapses and the ori-
entation complete signal (ORA) or ori-
entation fault signal (ORM) is output.
9999 Not checked.
Motor brake and stop operation
Parameters referred to
When 1 is set in Pr.
350 and the 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 set-
ting.
