2 Basic Application

2.1 Introduction to Basic Application

The Basic Application is a simple and easy-to-use application. It is the default setting on delivery from the factory. Otherwise select
the Basic Application in menu M6 on page S6.2. See the User Manual of the product.

Digital input DIN 3 is programmable.
The parameters of the Basic Application are explained in Chapter Parameter descriptions of this manual. The explanations are ar-

ranged according to the individual ID number of the parameter.

2.1.1 Motor Protection Functions in the Basic Application

The Basic Application provides almost all the same protection functions as the other applications:

•

External fault protection

•

Input phase supervision

•

Undervoltage protection

•

Output phase supervision

•

Earth fault protection

•

Motor thermal protection

•

Thermistor fault protection

•

Fieldbus fault protection

•

Slot fault protection

Unlike the other applications, the Basic Application does not provide any parameters for choosing the response function or limit
values for the faults. For more information on the motor thermal protection, see 10.336 (ID 704) Motor Thermal Protection and

10.614 Parameters of Motor Thermal Protection (IDs 704–708).

Application Guide

Standard Application

3 Standard Application

3.1 Introduction to Standard Application

Select the Standard Application in menu M6 on page S6.2.
The Standard Application is typically used in pump and fan applications and conveyors for which the Basic Application is too limited

but where no special features are needed.

•

The Standard Application has the same I/O signals and the same control logic as the Basic Application.

•

Digital input DIN 3 and all the outputs are freely programmable.

Extra functions:

•

Programmable Start/Stop and Reverse signal logic

•

Reference scaling

•

One frequency limit supervision

•

Second ramps and S-shape ramp programming

•

Programmable start and stop functions

•

DC brake at stop

•

One prohibit frequency area

•

Programmable U/f curve and switching frequency

•

Auto restart

•

Motor thermal and stall protection: Programmable action; off, warning, fault

The parameters of the Standard Application are explained in Chapter Parameter descriptions of this manual. The explanations are
arranged according to the individual ID number of the parameter.

Local/Remote Control Application

4 Local/Remote Control Application

4.1 Introduction to Local/Remote Control Application

Select the Local/Remote Control Application in menu M6 on page S6.2.
With the Local/Remote Control Application, it is possible to have two different control places. For each control place the frequency

reference can be selected from either the control panel, I/O terminal, or fieldbus. The active control place is selected with the digital
input DIN 6.

•

All outputs are freely programmable.

Extra functions:

•

Programmable Start/Stop and Reverse signal logic

•

Reference scaling

•

One frequency limit supervision

•

Second ramps and S-shape ramp programming

•

Programmable start and stop functions

•

DC brake at stop

•

One prohibit frequency area

•

Programmable U/f curve and switching frequency

•

Auto restart

•

Motor thermal and stall protection: Programmable action; off, warning, fault

The parameters of the Local/Remote Control Application are explained in Chapter Parameter descriptions of this manual. The ex­planations are arranged according to the individual ID number of the parameter.
