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).

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.
