Advanced commissioning
6.1 Overview of the inverter functions
Functions relevant to all applications
The functions that you require in each application are shown
in a dark color in the function overview above.
In the quick commissioning, the parameters of these func-
tions are assigned an appropriate basic setting, so that in
many cases the motor can be operated without having to
assign any other parameters.
Inverter control is responsible for all of the other
inverter functions. Among other things, it defines
how the inverter responds to commands from
the higher-level control system.
Inverter control (Page 153)
The commands from the higher-level control are
sent to the inverter via digital inputs or the
fieldbus. The inverter returns its status signals to
the outputs of the Control Unit or to the fieldbus.

You must define a setpoint , which defines the
motor speed, for example.
Setpoints (Page 203)
The setpoint processing uses a ramp-function
generator to prevent speed steps occurring and
to limit the speed to a permissible maximum
value.
Setpoint calculation (Page 211)
The motor closed-loop control ensures that the
motor follows the speed setpoint. You can select
either vector control or U/f control.

Functions required in special applications only
The functions whose parameters you only need to adapt
when actually required are shown in white in the function
overview above.
The protection functions prevent damage to the
motor, inverter and driven load, e.g. using tem-
perature monitoring or torque monitoring.
Protection functions (Page 231)
Functions suitable for the application permit, for
example, a higher-level closed-loop pressure or
temperature control using the technology con-
troller.
Further, the inverter provides solution options
specifically for applications in the area of
pumps, fans and climate control systems
(HVAC).
