Overview of the converter functions

The inverter control controls all other functions of the inverter. The inverter control also
defines how the inverter responds to external control signals.
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.
The setpoint source defines how the speed setpoint for the motor is specified, e.g. via an
analog input or a fieldbus.
The setpoint calculation uses a ramp-function generator to prevent speed steps occurring
and to limit the speed to a permissible maximum value.
The motor closed-loop control ensures that the motor follows the speed setpoint.
