1.3 Adapting the inverter in line with the application

1.3.1 General basics

Inverters are used to improve and extend the starting and speed response of motors.

Adapting the inverter to the drive task

The inverter must match the motor that it is controlling and the drive task to be able to

optimally operate and protect the motor.

Although the inverter can be parameterized for very specific applications, many standard

applications function satisfactorily with just a few adaptations.

Use the factory settings (where possible)

In simple applications, the inverter already functions with its factory settings.

Only basic commissioning is required ... for simple, standard applications

Most standard applications function after just a few adaptations made during the basic

commissioning.

1.3.2 Parameter

Parameters are the interface between the firmware of the inverter and the commissioning

tool, e.g. an operator panel.

Adjustable parameters

Adjustable parameters are the "adjusting screws" with which you adapt the inverter to its

particular application. If you change the value of an adjustable parameter, then the inverter

behavior also changes.

Adjustable parameters are shown with a "p" as prefix, e.g. p1082 is the parameter for the

maximum motor speed.

Display parameters

Display parameters allow internal measured quantities of the inverter and the motor to be

read.

Display parameters are shown with a "r" as prefix, e.g. p0027 is the parameter for the

inverter output current.
