Refer to page 125 for other settings of Pr. 71.
∗2
Refer to page 127 for offline auto tuning.
Set the motor capacity and the number of motor poles.
Select the control method. (Pr. 800) (Refer to page 95)
Set the operation command. (Refer to page 50)
As required
Perform offline auto tuning. (Pr. 96) (Refer to page 127)
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.)
96
Perform secure wiring.
(Refer to page 14)
