VN- Power units with DC link reactor for extremely high active power component thanks to efficient converter topology – for the same drive power, the converter requires a lower line current than comparable converters
- Flux reduction through automatic adaptation of the motor current to the prevailing load conditions with closed-loop control modes
- V/f (ECO) and vector without sensor (SLVC) and savings of up to 5 % under partial load conditions
- High efficiency up to 98 %
- Local commissioning without specialized knowledge of converters thanks to default settings and graphical user interface
- Unique: SINAMICS SD memory card for pre-parameterization and cloning of converter data sets
- Data backup for easy replacement
- Commissioning/diagnostics and controlling of converters
- Specific firmware functions such as deragging or pipe fill mode
- Automatic restart: Application restart after a power failure or fault occurrence
- Flying restart: Connection of the converter when the motor is running
- Cascade connection: Load-dependent connection and disconnection of a maximum of three additional motors by the converter in order to provide a largely constant output power (implemented by means of an additional external circuit)
- Hibernation mode: Startup or shutdown of the drive when the relevant value drops below an external setpoint or the internal PID controller setpoint
- Real-time clock: For time-dependent process controls, e.g. to reduce the temperature of a heating control at night and with automatic daylight saving/standard time switchover
- Freely programmable logical function blocks for frame sizes FSA to FSG
- For simulating simple PLC functions
- Four integrated PID controllers: One PID controller for controlling the drive speed as a function of pressure, temperature, flowrate, fill level, air quality and other process variables; a further three PID controllers with freely configurable outputs, e.g. for controlling valves (heating, cooling) or flaps
- Emergency mode: Special converter operating mode that enhances the availability of the drive system in the event of a fire
- Bypass mode: When the setpoint is reached or a fault occurs, the system changes over to line operation (implemented by means of an additional external circuit)
- Programmable time switches
