Parameters (A) Application parameters
FR-A800 5 - 523
362
A520
Orientation position loop
gain
1 0.1 to 100
When the servo torque function is selected using Pr. 358,
the output frequency for generating servo torque gradually
increases to the creep speed of Pr. 352 according to the
slope set in Pr. 362. Although the operation becomes faster
when the value is increased, hunting may occur in the
machine.
363
A521
Completion signal output
delay time
0.5 s 0 to 5 s
The orientation complete signal turns ON after going into
the in-position width and waiting for the set time. Also, the
signal turns OFF after going out of the in-position width and
waiting for the set time.
364
A522
Encoder stop check time 0.5 s 0 to 5 s
If the orientation complete signal (ORA) has never been
output and the encoder stays stopped for the set time
without completing orientation, the orientation fault signal
(ORM) is output. If the ORA signal has been output before
but the orientation cannot be completed within the set
time, the ORM signal is also output.
365
A523
Orientation limit 9999
0 to 60 s
The time elapses after passing the creep switchover
position is measured. If orientation cannot be completed
within the set time, the orientation fault signal (ORM) is
output.
9999 Set to 120 s.
366
A524
Recheck time 9999
0 to 5 s
When the start signal is turned OFF with the 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.
9999 Not checked.

Number of encoder pulses 1024 0 to 4096
Set the number of encoder pulses.
Set the number of pulses before it is multiplied by 4.

Orientation is executed from
the current rotation direction.
Machine end orientation
11
Orientation is executed from
the forward rotation direction.
12
Orientation is executed from
the reverse rotation direction.

gear teeth
a 0 to 32767 Set the encoder orientation gear ratio.
395
A541
Number of motor side gear
teeth
396
A542
Orientation speed gain (P
term)
60 0 to 1000
Response level during position control loop (servo rigidity)
can be adjusted at orientation stop.
397

Orientation speed integral
time
0.333 0 to 20 s
398
A544
Orientation speed gain (D
term)
1 0 to 100 Lag/advance compensation gain can be adjusted.
399
A545
Orientation deceleration
ratio
20 0 to 1000
Make adjustment when the motor runs back at orientation
stop or the orientation time is long.
