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.
Set the rated motor voltage and frequency.
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) (
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.
REMARKS
 Use Pr. 89 to adjust the motor speed fluctuation at load fluctuation.
