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.

Initial Setting
Value Range
Orientation fault signal (ORM) is output when the encoder
remains stopped for the set time without orientation
completion in the state where no orientation complete
0.5s 0 to 5.0s
signal (ORA) is output. ORM signal is output when
orientation is not completed again in the set time in the
state where ORA signal is output.
Measure the time taken after passing the creep
0 to 60.0s switchover position and output the orientation fault signal
9999
(ORM) if orientation is not completed within the set time.
9999 Set to 120s.
Turning off the start signal with orientation command
(X22) on after stopping the motor by orientation control,
0 to 5.0s the present position is checked again after the set time
9999
elapses and the orientation complete signal (ORA) or
orientation fault signal (ORM) is output.
9999 Not checked.
Set the number of pulses of the encoder.
1024 0 to 4096
Set the number of pulses before multiplied by four.
0 Orientation is executed from the current rotation direction.
0 1 Orientation is executed from the forward rotation direction.
2 Orientation is executed from the reverse rotation direction.
60 0 to 1000
Response level during position control loop (servo rigidity)
at orientation stop can be adjusted.
0.333 0 to 20.0s
1 0 to 100.0 Lag/advance compensation gain can be adjusted.
Make adjustment when the motor runs back at orientation
20 0 to 1000
stop or the orientation time is long.
