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.

Orientation control invalid
Turning ON the X22 signal decelerates the motor speed to
2 Hz
0 to 30 Hz
the set value.
0 to 10 Hz After the speed reaches the orientation speed, the speed
0.5 Hz
decreases to the creep speed set in Pr. 352 as soon as the
current position pulse reaches the creep switchover
511
0 to 16383
position set in Pr. 353.
As soon as the current position pulses reach the set position
96
0 to 8191
loop switchover position, control is changed to the position
loop.
After the motor moves into the position loop, the motor
stops by the DC injection brake when the current position
5
0 to 255
pulses reach the specified start position of the DC injection
brake.
When "0" is set in Pr. 350, the internal position command is
0
0 to 16383
activated and the setting value of Pr. 356 becomes the stop
position.
5
0 to 255
Set the in-position width at a stop of the orientation.

0 to 13
Operation at orientation completion can be selected.
Set when using a motor for
0
which forward rotation
(encoder) is clockwise viewed
from the shaft.
100
1
Set when using a motor for
1
which forward rotation
(encoder) is counterclockwise
viewed from the shaft.

Speed command
16-bit data is used as the
1
external position command as
is.
0
Set the stop position by
2 to 127
dividing up to 128 stop
positions.
Shift the home position using a compensation value
without changing the home position of the encoder. The
0
0 to 16383
stop position is a position obtained by adding the setting of
Pr. 361 to the position command.
(A) Application parameters
Set for the operation at
120 Hz or less.
Set for the operation at a
frequency higher than
CW
120 Hz.
Set for the operation at
120 Hz or less.
Set for the operation at a
frequency higher than
CCW
120 Hz.
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.
