For customers replacing the
conventional model with this
inverter
Replacement of the FR-A700 series
FR-A760
V/F control
Advanced magnetic flux vector control
Real sensorless vector control
Vector control (with plug-in option )
Built in for the FR-A760-00330 or lower
400 Hz
120 Hz

―
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 switching signal (X18) 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
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.
FR-DU07 (4-digit LED)
FR-PU07
FR-A860
V/F control
Advanced magnetic flux vector control
Real sensorless vector control
Vector control (with plug-in option/control terminal
option)
PM sensorless vector control (IPM motor/SPM
motor)
Built in for the FR-A860-01080 or lower
590 Hz

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)"
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)
None (FR-DU07 is not supported.)
FR-LU08 (LCD)
FR-PU07 (Some functions, such as parameter
copy, are unavailable.)
