As required
Perform offline auto tuning. (Pr. 96) (Refer to page 105)
Set motor excitation current. (Pr. 82) (Refer to page 105)
Set slip compensation. (Pr. 245, Pr. 246, Pr. 247) (Refer to page 78)
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.
