“A” Group: Standard Functions

Basic Parameter Settings

These settings affect the most fundamental behavior of the inverter—the outputs to the
motor. The frequency of the inverter’s AC output determines the motor speed. You may
select from three different sources for the reference speed. During application develop-
ment you may prefer using the potentiometer, but you may switch to an external source
(control terminal setting) in the finished application, for example.

The base frequency and maximum frequency settings interact according to the graph
below (left). The inverter output operation follows the constant V/f curve until it reaches
the full-scale output voltage. This initial straight line is the constant-torque part of the
operating characteristic. The horizontal line over to the maximum frequency serves to let
the motor run faster, but at a reduced torque. If you want the motor to output constant
torque over its entire operating range (limited to the motor nameplate voltage and
frequency rating), then set the base frequency and maximum frequency equal as shown
(below right).

NOTE:

The “2nd motor” settings in the tables in this chapter store an alternate set of

parameters for a second motor. The inverter can use the 1st set or 2nd set of parameters
to generate the output frequency to the motor. See

“Configuring the Inverter for Multiple

Motors” on page 4–40
