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.)
