"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
Keypad potentiometer – The range of rotation of the knob
matches the range defined by B082 (Start frequency
adjustment) to A004 (Maximum frequency setting)
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
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.
