The FRENIC-MEGA is a general-purpose inverter whose operation is customized by frequency-
asis drive control, however, the control target is a motor speed, not
frequency, so convert the frequency to the motor speed according to the following expression.
Motor speed (r/min) = 120 × Frequency (Hz) ÷ Number of poles
