5.14.8 Orientation control
The inverter can adjust the stop position (Orientation control) using a position detector (encoder) at-
tached to a place such as the main shaft of the machine.
A vector control compatible option is required.
Because Pr. 350 "Stop position command selection" is initially set to "9999", the orientation control
function is invalid.

A526
Orientation speed 2 Hz 0 to 30 Hz
Turning ON the X22 signal decelerates the motor speed to
the set value.
352
A527
Creep speed 0.5 Hz 0 to 10 Hz After the speed reaches the orientation speed, the speed
decreases to the creep speed set in Pr. 352 as soon as the
current position pulse reaches the creep switchover
position set in Pr. 353.
353
A528
Creep switchover position 511 0 to 16383
354
A529
Position loop switchover
position
96 0 to 8191
As soon as the current position pulses reach the set position
loop switchover position, control is changed to the position
loop.
355
A530
DC injection brake start
position
5 0 to 255
After the motor moves into the position loop, the motor
stops by the DC injection brake when the current position
pulses reach the specified start position of the DC injection
brake.
356
A531
Internal stop position
command
0 0 to 16383
When "0" is set in Pr. 350, the internal position command is
activated and the setting value of Pr. 356 becomes the stop
position.
357
A532
Orientation in-position
zone
5 0 to 255 Set the in-position width at a stop of the orientation.
358
A533
Servo torque selection 1 0 to 13 Operation at orientation completion can be selected.

Encoder rotation direction 1
0
Set when using a motor for
which forward rotation
(encoder) is clockwise viewed
from the shaft. Set for the operation at
120 Hz or less.
100
Set for the operation at a
frequency higher than
120 Hz.
1
Set when using a motor for
which forward rotation
(encoder) is counterclockwise
viewed from the shaft. Set for the operation at
120 Hz or less.
101
Set for the operation at a
frequency higher than
120 Hz.

A511
16-bit data selection 0
0 Speed command
When Pr. 350 = "1" is set
and the FR-A8AX is
mounted together, set the
stop position using 16-bit
data.
Stop position command is
input as binary regardless
of the Pr. 304 setting.
1
16-bit data is used as the
external position command as
is.
2 to 127
Set the stop position by
dividing up to 128 stop
positions.
361
A512
Position shift 0 0 to 16383
Shift the home position using a compensation value
without changing the home position of the encoder. The
stop position is a position obtained by adding the setting of
Pr. 361 to the position command.
