Drive control
The FRENIC-MEGA runs under any of the following drive controls. Some functional codes assigned apply
exclusively to the specific drive control, which is indicated by letters Y (Applicable) and N (Not applicable) in
the "Drive control" column of the functional code tables.

The FRENIC-MEGA is a general-purpose inverter whose operation is customized by
frequency-basis function codes, with drive controls equivalent to conventional inverters. Unde
the speed-basis drive control, however, the control target is a motor speed, not a frequency, so
convert the frequency to the motor speed according to the following equation.
Equation: Motor speed (r/min) = 120 x Frequency (Hz) / Number of poles
