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 sensing the voltage/current of the incoming cable and the power of individual motor-unit by transmitting the sensing voltage sampling data to all Accura 2750P[C]s that are connected at the internal communication cable.
It uses internal communication cable to deliver/receive the measurement data, motor control command and operation state from multiple Accura 2750P[C] at MCC and through Accura 2750LCG it also manages the measurement data, motor control command and operation state from multiple Accura 2750LC[I] at LOP(Local Operating Panel) by delivering/receiving. By transmitting this data to incoming-unit integrated HMI module Accura 2700DW, it makes it possible to confirm the operation state of all motors, and is connected to host system through Ethernet and RS-485 external communication.
