5.2 Function Code Tables

Drive control
The FRENIC-MEGA runs under any of the following control methods. Some function codes apply exclusively to the
specific control method.
The enable or disable status is indicated with an icon for each control method within the permissible setting range
field in the function code list table.
Icon example: Under V/f control Enable: Disable:

setting range field
V/f control
Dynamic torque vector control (F42 = 1)
V/f control with slip compensation (F42=2)
V/f control with speed sensor (F42 = 3)
Dynamic torque vector control with speed sensor (F42 = 4)
Sensorless vector control (F42 = 5)
Vector control with speed sensor (F42 = 6)
Sensorless vector control (synchronous motors) (F42 = 15)
Vector control with sensor (synchronous motors) (F42 = 16)
Vector control (F42=5, 6, 16)
For details on the control method, refer to “Function code F42”.
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 x frequency (Hz)/number of poles
Control method icon group display
The function code list table contains locations where control method icons are displayed in groups as
shown below.
Display example: Electronic thermal overload relay (F10 to F12) control icon display
In this example, F11 and F12 indicate that the same control
methods as F10 is valid.
Function code group: Excluding certain exceptions, all control methods (
) for U codes, y codes, o codes, and K codes are valid, and therefore the control icons have been
omitted from the table.
