Accura 2700M Incoming-Unit Integrated Module
Accura 2700M is mounted at the MCC incoming-unit and performs the master function of the smart motor management system. It measures the power of entire MCC by sensing the voltage and current of incoming power cable, and transmits the voltage sampling data to all Accura 2750P[C] that are connected to the internal communication cable. Therefore all Accura 2750P[C] that are received the voltage sampling data can measure the power of individual motor-unit by sensing only current of individual motor-unit. It sends and receives measurement data, motor control command and operating state from multiple A ccura 2750P[C] in MCC using RS-485 internal communication line. It also sends and receives this data to many Accura 2750LC in LOP through Accura 2750LCG. It makes it possible to confirm the operating state of all motors in front of MCC by transmitting these data obtained above to incoming-unit integrated module HMI display Accura 2700DW, and it is connected to host system through Ethernet and/or RS-485 communication.
