Advanced commissioning
6.1 Overview of converter functions
The free function blocks permit configurable signal processing within the converter.
You can select in which physical units the converter represents its associated values.
Safety functions
The safety functions fulfill increased requirements regarding the functional safety of the
drive.
Setpoints and setpoint processing
The setpoint normally defines 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 control receives the setpoint either from the higher-level control or from the
technology controller.
Motor control
The motor control ensures that the motor follows the speed setpoint. You can choose
between various control modes.
The converter provides several methods to brake the motor electrically. During electrical
braking, the motor develops a torque that reduces the speed to standstill.
Protection of the drive and the driven load
The protection functions prevent damage to the motor, converter and driven load.
