Decrease the motor speed to the set value
0.01Hz 2Hz 0 to 30Hz
when the orientation command (X22) is given.
As soon as the current position pulse
0.01Hz 0.5Hz 0 to 10Hz
reaches the creep switchover position set
in Pr.353 after the speed has reached the
1 511 0 to 16383
orientation speed, the speed decelerates
down to the creep speed set in Pr.352.
As soon as the current position pulse
1 96 0 to 8191 reaches the set position loop switchover
position, control is changed to position loop.
After changed to position loop, DC injection
brake is applied and the motor stops as
1 5 0 to 255
soon as the current position pulse reaches
the set DC injection brake start position.
When "0" is set in Pr. 350, the internal
position command is activated and the
1 0 0 to 16383
setting value of Pr. 356 becomes a stop
position.
Set the in-position zone at a stop of the
1 5 0 to 255
orientation.
Functions at orientation completion can be
1 1 0 to 13
selected.

stop positions at
regular intervals.
Shift the origin using a compensation value
without changing the origin of the encoder.
1 0 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 1 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.

When 1 is set in
Pr.350 and the
option FR-A7AX is
mounted, set a stop
position using 16-

as binary
regardless of the
Pr.304 setting.
