Advanced commissioning
6.1 Overview of the converter functions
The inverter provides a motor holding brake control. The motor holding brake holds the motor
in position when it is switched off.
The free function blocks permit configurable signal processing within the inverter.
You can select in which physical units the inverter represents its associated values.
You can activate additional monitoring functions in the inverter.
Safety functions
The safety functions fulfill increased requirements regarding the functional safety of the drive.
The extended safety functions monitor the drive speed. You require a license to operate the
inverter with the extended safety functions.
The extended safety functions are described in the "Safety Integrated" function manual.
Setpoints and setpoint conditioning
The setpoint generally determines the motor speed.
The setpoint processing uses a ramp-function generator to prevent speed steps occurring and
to limit the speed to a permissible maximum value.
Technology controller
The technology controller controls process variables, e.g. pressure, temperature, level or flow.
The motor closed-loop control either receives its setpoint from the higher-level control - or from
the technology controller.
Basic positioner
The basic positioner traverses an axis with position control to a target position.
You require a license to use the basic positioner.
The basic positioner is described in the "Basic positioner" function manual.
