Siemens supplies almost all the technology for the centrifuges at Nordzucker. These include, for example, the SIMATIC S7-1200 PLC (programmable logic controller), the KTP700 human-machine interface (HMI), the control devices, the motor, the circuit breaker, fuseless load feeders (consisting of motor circuit breakers and contactors), and the soft starter from the new 3RW5 series. The 3RW55F soft starter provides new features such as communication via Profibus, Profinet, Ethernet and Modbus, transparent operation, compact design and hybrid switching technology.
For me, it is important that the machine start-up is optimally controlled and the power loss is low.
