PID control
Turn the X14 signal ON to enable PID control.
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.

Restart operation
Turn the CS signal ON to enable restart.
Restart is enabled by turning ON the CS signal, or
solely setting
Pr.57 if the CS signal is not assigned
to any input terminal.

V/F control switching
The V/F switching signal (X18) is valid when Pr.81
= "12 to 20 (2 to 10 poles)".
Pr.81 = "12 (12 poles)"
X18 is valid regardless of the Pr.81 setting. (The
Pr.81 settings "14 to 20" are not available.)
PTC thermistor input
Input from the terminal AU (The function of the
terminal AU is switched by a switch.) Input from the terminal 2. (The function of the
terminal 2 is switched by the
Pr.561 setting.)

Terminal response level
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.
