Turn the X14 signal ON to enable PID
control.
Turn the CS signal ON to enable restart.
Time period from restoration of power until
the operation is restarted
The V/F switchover (X18) signal is valid
when Pr.81 = "12 to 20" (2 to 10 poles).
Input through terminal AU (The function of
terminal AU is switched by a switch.)
B connector
Removable terminal block (screw type)
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.

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 is enabled by turning ON the CS signal, or solely setting
Pr.57 if the CS signal is not assigned to any input terminal.
Time period from occurrence of instantaneous power failure
until the operation is restarted
Pr.81 = "12" (12 poles)
The X18 signal is valid regardless of the Pr.81 setting. (The
Pr.81 settings "14 to 20" are not available.)
Input through terminal 2 (The function of 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 such as Parameter copy are
unavailable.)
The FR-DU07 is not supported.
