1.3 Adapting inverters to the application (parameterization for entry level
personnel)
1.3.1 General basics
Parameterizable inverters transform standard motors into variable-speed drives
Inverters are parameterized to adapt them to the motor being driven so that this can be
optimally operated and protected. This is realized using one of the following operator units:
● Keyboard and display unit (Operator Panel) that is snapped onto the inverter.
● Software (STARTER commissioning tool) that allows the inverter to be parameterized
and controlled from a PC.
Inverters are especially used to improve and expand the starting and speed response of
motors.
Many standard applications can function with the default parameters
Although inverters can be parameterized for very specific applications, many standard
applications can be configured by means of just a few parameters.
Use the factory settings (where possible)
For basic applications, commissioning can be carried out using just the factory settings (see
Section "Commissioning with factory settings" (Page 51)).
Use quick commissioning (for simple, standard applications)
In the majority of standard applications, commissioning can be carried out by entering or
changing just a few parameters during quick commissioning (see Section "Commissioning
with Operator Panel" (Page 71)).
