1.3 Adapting inverter to 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.
