Functions, which you need to set in any application with
position control
Functions, which you only require in special applications or
which you must adapt
The functions that you must set in every application with
position control are shown in a dark color in the function
overview above.
The functions whose parameters you only need to adapt
when actually required are shown in white in the function
overview above.
Inverter control
is responsible for all of the other
inverter functions. Among other things, it defines
how the inverter responds to external control
signals.
Inverter control (Page 113)
The
setpoint source
defines how the speed
setpoint for the motor is specified, e.g. via a
fixed setpoint or the fieldbus.
Setpoints (Page 119)
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.
Adapt inputs and outputs (Page 79)
Configuring the fieldbus (Page 85)
You only require
setpoint processing
if you
operate the inverter without position controller,
which means you only operate it in the speed
controlled mode.
Setpoint calculation (Page 126)
The
motor closed-loop control
ensures that the
motor follows the speed setpoint.
Motor control (Page 136)
The
protection and monitoring
functions avoid
overloads and operating states that could cause
damage to the motor, inverter and driven load.
The motor temperature monitoring, for example,
is set here.

The
basic positioner
traverses an axis with
position control to a target position.

The
application-specific
functions are available,
e.g. to control a motor holding brake.
Application-specific functions (Page 218)
The
safety functions
are used in applications
that must fulfill special requirements in terms of
functional safety.

The extended safety functions monitor the drive
speed.
The extended safety functions are described in
the "Safety Integrated Function Manual", also
refer to Section: Manuals for your inverter
