"A" Group: Standard Functions
The inverter provides flexibility in how you control Run/Stop operation and set the
output frequency (motor speed). It has other control sources that can override the A001 /
A002 settings. Parameter A001 sets the source selection for the inverter's output
frequency. Parameter A002 selects the Run command source (for FW or RV Run
commands). The default settings use the input terminals for –FE (European) models,
and the keypad for –FU (USA) models.

Frequency Source
POT on ext. operator – The range of rotation of the knob
matches the range defined by b082 (start frequency) to A004
(max. frequency), when external operator is used
Control terminal – The active analog input signal on analog
terminals [O] or [OI] sets the output frequency
Function F001 setting – The value in F001 is a constant, used
for the output frequency
ModBus network input – The network has a dedicated register
for inverter output frequency
Option – Select when an option card is connected and use the
frequency source from the option
Pulse train input – The pulse train given to EA terminal. The
pulse train must be 10Vdc, 32kHz max.
Via EzSQ – The frequency source can be given by the EzSQ
function, when it is used
Calculate function output – The Calculated function has
user-selectable analog input sources (A and B). The output can
be the sum, difference, or product (+, -, x) of the two outputs.
