“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
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
-
01
Control terminal – The active analog input signal on analog
terminals [O] or [OI] sets the output frequency
4-70, 3-16, 3-40,
3.83
02
Function F001 setting – The value in F001 is a constant, used
for the output frequency
3-11
03
ModBus network input – The network has a dedicated register
for inverter output frequency
B-24
04
Option – Select when an option card is connected and use the
frequency source from the option
(manual of each
option)
06
Pulse train input – The pulse train given to EA terminal. The
pulse train must be 10Vdc, 32kHz max.
3-113
07
Via EzSQ – The frequency source can be given by the EzSQ
function, when it is used
(EzSQ manual)
10
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.
