Drive control
The EQ7 runs under any of the following drive controls. Some function codes apply exclusively to the specific drive control, which is
indicated by letters Y (Applicable) and N (Not applicable) in the "Drive control" column in the function code tables given on the following
pages.

For details about the drive control, refer to "Function code F42 (Drive Control Selection 1)."
The EQ7 is a general-purpose inverter whose operation is customized by frequency-basis function codes, like
conventional inverters. Under 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 expression.
Motor speed (r/min) = 120 Frequency (Hz) Number of poles
