„ Drive control
The FRENIC-MEGA 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 FRENIC-MEGA 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

Note: Difference of notation between standard keypad and remote keypad
Descriptions in this manual are based on the standard keypad having an LCD monitor and a
five
-digit, 7-segment LED monitor (as
shown in Chapter 3). The FRENIC-MEGA also provides a remote keypad as an option, which has no LCD monitor and has a
four
-digit, 7-segment LED and a USB port.
If the standard keypad is replaced with an optional remote keypad, the display notation differs as shown below.
