Accura 2700/2750
Accura 2750LC[I] LOP Control Module
Accura 2750LC[I] is LOP digital control module that substitutes totally the existing LOP[Local Operating Panel] that consists of push button, lamp, selection switch, current meter etc. Accura 2750LC performs the running command at the field and display state and measurement through Accura 2750LCG and RS-485 communication with Accura 2700M. Adding to the functions of Accura 2750LC, INVERTER/BYPASS buttons are provided at the front of Accura 2750LCI.
At the existing LOP, command is transmitted to Accura 2750PC through the signal cable that connects the contact point of push button with the digital input of corresponding Accura 2750PC by pressing the push button of LOP to RUN/STOP command. However, at Accura 2750LC[I], control command is transmitted to Accura 2700M through Accura 2700M by touching pressing RUN/STOP button, and Accura 2700M performs RUN/STOP command by transmitting the command to corresponding Accura 2750PC of motor-unit through communication. This communication method has a strong point that a lot of signal cables that connect from MCC to LOP at the existing system can be substituted with one communication cable, and disconnection and short-circuit state of the cable can be immediately noticed.
Accura 2750LCG supports communication redundancy through RS-485 communication of ring connection using 2 Accura 2750LC[I] communication ports.
Connection with Accura 2750LCG (RS-485 Communication)
Accura 2750LCG performs gateway function between Accura 2700M and Accura 2750LC[I]
LOP command of corresponding motor-unit is transmitted to Accura 2750PC through Accura 2750LCG and Accura 2700M
The current/power data of corresponding motor-unit and the motor running state are transmitted from Accura 2750PC to Accura 2750LC[I] through Accura 2700M and Accura 2750LCG
RS-485 based internal-use protocol 2 ports (LC_A, LC_B) (Function of each ports is same)
2 ports: ring connection Communication Redundancy
Connector type RJ45 connector
Communication cable Ethernet cable Cat 5e FTP, STP, SFTP
Communication cable total length Maximum 800m for each group
