Setting functions
8.1 Overview of the converter 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.
You set these functions during the basic commissioning, so
that in many cases, the motor can be operated without
having to make any additional settings.
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 217)
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.

Configuring the fieldbus (Page 111)
You must define a setpoint , which defines the
motor speed, for example.
Setpoints (Page 229)
The setpoint calculation uses a ramp-function
generator to prevent speed steps occurring and
to limit the speed to a permissible maximum
value.
Setpoint calculation (Page 235)
The motor closed-loop control ensures that the
motor follows the speed setpoint. You can select
either closed-loop speed 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
temperature monitoring or torque monitoring.
Protection functions (Page 255)
Functions suitable for the application permit, for
example, a motor holding brake to be controlled,
a higher-level closed-loop pressure or
temperature control to be implemented using the
technology controller.
Application-specific functions (Page 260)
The safety functions fulfill increased
requirements regarding the functional safety of
the drive.
The basic functions safely switch off the drive
torque.

The extended safety functions monitor the drive
speed. You require a license to use the extended
functions, also refer to Section: Activating
licensed functions (Page 413).
The extended safety functions are described in
the "Safety Integrated Function Manual", also
refer to Section: Manuals for your converter
(Page 461).
The basic positioner traverses an axis with
position control to a target position.
You require a license to use the basic positioner,
also refer to Section: Activating licensed
functions (Page 413).
The basic positioner is described in the "Function
Manual, Basic Positioner", also see Section:
Manuals for your converter (Page 461).
