9.4 Setting Parameters F(Basic) and C(Advanced) Fig. 9.4.1
The basic parameters F can be accessed in two ways; via the keypad or through the MODBUS
protocol using an optional communications module. Here we will describe keypad access. Before
proceeding, refer to the F and C parameter lists (Sec. 10) and note that some parameters must be
changed with the inverter in the STOP mode while others can be changed in either the RUN or STOP
mode. Also, changing certain parameters may affect other functions and should be carefully
considered before making those changes.
To enter the F parameters, press the DSP / FUN key; the display should show F00. Using the Λ / V
keys, select the parameter to set and then press the DATA / ENT key. The display should be showing
the existing code or function for that parameter. Using the Λ / V keys, select the desired code or
function and then press the DATA / ENT key to save; the display should momentarily flash End and
return to the F menu. To enter the C (advanced) parameters select F51 and then Code = 001; C00
will be displayed. Using the same procedure in setting the F parameters scroll to the desired C
parameter and select the code or function to be set and then press the DATA / ENT key to save. To
return to the F parameter list press the DSP / FUN key twice and set F51 to Code = 000. After all
parameter changes have been made, press the DSP / FUN key to return the display show the output
frequency.
