Refer to page 144, for other settings of Pr. 71.
∗2
Refer to page 146 for offline auto tuning.
Set the motor capacity and the number of motor poles.
Select the control method.(Pr. 800) (Refer to page 117)
Set the operation command. (Refer to page 103)
As required
Perform offline auto tuning. (Pr. 96) (Refer to page 146)
Set slip compensation. (Pr. 245, Pr. 246, Pr. 247) (Refer to page 119)
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.)
