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
10.621 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.
