“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 Setting – For parameter A001, the following table provides a further
description of each option, and a reference to other page(s) for more information.
Code Frequency Source Refer to page(s)…
00 Keypad potentiometer – The range of rotation of the knob
matches the range defined by B082 (Start frequency
adjustment) to A004 (Maximum frequency setting)

01 Control terminal – The active analog input signal on analog
terminals [O] or [OI] sets the output frequency

02 Function F001 setting – The value in F001 is a constant,
used for the output frequency

user-selectable analog input sources (A and B). The output
can be the sum, difference, or product (+, -, x) of the two
outputs.
