Refer to Chapter 4 of the FR-E700 Instruction Manual (Applied) for other settings of Pr. 71 and offline auto tuning.
Set the motor overheat protection. (Pr. 9) (Refer to page 36)
Set the motor capacity and the number of motor poles.
(Pr. 80, Pr. 81) (Refer to page 32)
Set the rated motor voltage and frequency.
(Pr. 83, Pr. 84) (Refer to page 32)
Select the control method.(Pr. 800) (Refer to page 32)
Set the operation command. (Refer to page 24)
As required
 Perform offline auto tuning. (Pr. 96) (
 Set slip compensation. (Pr. 245, Pr. 246, Pr. 247) (
NOTE
 Uneven rotation slightly increases as compared to the V/F control. (It is not suitable for machines such as grinding
machine and wrapping machine which requires less uneven rotation at low speed.)
 When a surge voltage suppression filter (FR-ASF-H/FR-BMF-H) is connected between the inverter and motor, output
torque may decrease.
Perform secure wiring.

Set the rated motor current (A) in Pr.9 Electronic thermal O/L relay.
Set motor capacity (kW) in Pr. 80 Motor capacity and
the number of motor poles (number of poles) in Pr. 81 Number of motor poles.
(V/F control is performed when the setting is "9999" (initial value).
Set the rated motor voltage (V) in Pr.83 Rated motor voltage, and
set the rated motor frequency (Hz) in Pr.84 Rated motor frequency.
Set "30" in Pr. 800 to make General-purpose magnetic flux vector control valid.
Select the start command and speed command.
