Turn the X14 signal ON to enable PID control.
Turn the CS signal ON to restart.
The V/F switchover (X18) signal is valid when
Pr.81 = "12 to 20 (2 to 10 poles)".
Input from the terminal AU
(The function of the terminal AU is switched by a
switch.)
B connector
The FR-A800's I/O terminals have better response level than the FR-A700's terminals. By setting Pr.289
Inverter output terminal filter and Pr.699 Input terminal filter, the terminal response level can be
compatible with that of FR-A700. Set to approximately 5 to 8 ms and adjust the setting according to the
system.
FR-DU07 (4-digit LED)
FR-PU07
Dedicated plug-in options (not interchangeable)
Connected to the connector 3.
Installation size is not compatible. (New mounting holes are required.)
Built in for all capacities
DC reactor (FR-HEL) is provided.

When the X14 signal is not assigned, just set a value in
Pr.128 to enable PID control.
When the X14 signal is assigned, turn the X14 signal ON
while Pr.128 ≠ "0" to enable PID control.
The PID pre-charge function and dancer control are
added.
CS signal assignment not required. (Restart is enabled
with the Pr.57 setting only.)
Pr.81= "12 (12 poles)"
X18 is valid regardless of the Pr.81 setting. (The Pr.81
settings "14 to 20" are not available.)
Input from the terminal 2.
(The function of the terminal 2 is switched by the Pr.561
setting.)
Mini B connector
Removable terminal block (spring clamp type)
FR-DU08 (5-digit LED)
FR-LU08 (LCD operation panel)
FR-PU07 (Some functions are unavailable.)
FR-DU07 is not supported.
Connected to the connector 1.
The converter unit (FR-CC2) is required.
