Functions relevant to all applications
The functions that you require in each application are located at the center of the function
overview above.
The parameters of these functions are provided with a matching basic setting during quick
commissioning so that in many cases, the motor can be operated without requiring additional
parameterization.
Inverter control
is responsible for all of the other inverter functions. Among
other things, it defines how the inverter responds to external control signals.
The command source
defines from where the control signals are received to
switch
-on the motor, e.g. via digital inputs or a fieldbus.
The setpoint source defines how the speed setpoint is for the motor is entered,
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.
Functions required in special applications only
The functions, whose parameters you only have to adapt when actually required, are located
at the outer edge of the function overview above.
The production functions
avoid overloads and operating states that could
cause damage to the motor, inverter and driven load. The motor temperature
m
onitoring is, e.g. set here.
The technological functions
allow you to activate a motor holding brake or
implement a higher
-level pressure or temperature control using the tech
nology
controller, for example.
