17.4.3 Setting Parameters b(Basic) and A(Advanced)
The accessing and setting of parameter groups b and A will be discussed next.
Important ! The A (Advanced) parameters are not directly accessible and must be enabled by setting
parameter b011=0001.
Setting b (Basic) parameters
The basic parameters b can be accessed in two ways; the keypad or through the MODBUS protocol using an
optional communications module. Here only keypad access will be described. Before proceeding, refer to the b and
A parameter list (Sec. 19.0) 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 also affect
other functions and should be considered before making those changes.
To enter the b parameters, press the DSP/ FUN key; the display should show b000. Using the
> / RESET key to select the digit position and the Λ / V keys to select the value, enter the parameter to be set and
then press the READ / ENTER key to save; the display should momentarily flash End and return to the parameter
selected.
Setting A (Advanced) parameters
As previously mentioned, the A parameters are not directly accessible and must be enabled. To do this, select
parameter b011 and then Code = 0001 (Enable). Press the READ / ENTER key to save; the display should be
showing b011. Using the > / RESET key scroll to b000 position and then press the Λ key; A000 will be displayed.
Using the same procedure in setting the b parameters scroll to the desired A parameter and select the code or
function to be set and then press the READ / ENTER key to save. After all parameter changes have been made,
