The above parameters can be set when the FR-A7AP (option) is mounted.
* When the operation panel (FR-DU07) is used, the maximum setting is 9999. When a parameter unit is used, up to the maximum value within
the setting range can be set.
(1) Setting
If the orientation command signal (X22) is turned on during operation after the various parameters have been set, the
speed will decelerate to the "orientation switchover speed". After the "orientation stop distance" is calculated, the speed
will further decelerate, and the "orientation state" (servo lock) will be entered. The "orientation complete signal" (ORA)
will be output when the "orientation complete width" is entered.

Used to enter an orientation signal for orientation.
For the terminal used for X22 signal input, set "22" in any of Pr. 178 to Pr. 189 to assign
the function.
Common terminal for the orientation signal.
Switched low if the orientation has stopped within the in-position zone while the start
and orientation signals are input.
For the terminal used for the ORA signal output, assign the function by setting "27
(positive logic) or 127 (negative logic)" in any of Pr. 190 to Pr. 196.
Switched low if the orientation has not stopped within the in-position zone while the
start and orientation signals are input.
For the terminal used for the ORM signal output, assign the function by setting "28
(positive logic) or 128 (negative logic)" in any of Pr. 190 to Pr. 196.
Common terminal for the ORA and ORM open collector output terminals.
Description
Measure the time taken after passing the creep
switchover position and output the orientation fault signal
(ORM) if orientation is not completed within the set time.
Set to 120s.
Turning off the start signal with 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.
Not checked.
Set the number of pulses of the encoder.
Set the number of pulses before multiplied by four.
