Accura 2700/2750
|
Mounted at the MCC incoming-unit, Accura 2700M performs the main function of the Smart Motor Management System. It measures the power consumed at the entire MCC by sensing the voltage/current of the incoming line and the power of the individual motor-unit by sending the sampled voltage data to all Accura 2750P[C] modules connected with the internal communication cable. Through the cable, it delivers/receives measurement and motor control commands and operating status data to/from multiple Accura 2750P[C] modules at the MCC. It also sends/receives those data to/from multiple Accura 2750LC[I] modules at the LOP(Local Operating Panel) through Accura 2750LCG. By sending this data to Accura 2700D, the integrated incoming-unit HMI module, it allows users to check the operation state of all motors in front of the MCC panel. It is connected to the host system through Ethernet and RS-485 communication. |

Installed at the individual motor unit in the MCC, Accura 2750P mainly protects the motor by measuring the current supplied to the motor. It also measures the various power characteristics of the individual motor-unit based on the current signal data measured by the built-in CT and the voltage signal data received from Accura 2700M via communication. For a motor-unit driven by an inverter, it measures the various power characteristics of the individual motor unit by receiving the sampled output voltage data of the inverter processed with the Low Pass Filter(LPF) from Accura 2750INV/VOL module via communication. Accura 2750PC provides the motor control function along with the measurement and protection function of Accura 2750P. | ||

The output voltage signal of the inverter is required to measure the inverter's output power in the motor-unit driven by the inverter. Accura 2750INV/VOL module processes the inverter output voltage with the Low Pass Filter(LPF) to generate voltage data and transmits it to Accura 2750PC module via communication. It also supports a separate RS-485 communication port to communicate with the inverter supporting RS-485 communication. By providing additional digital I/O channels, Accura 2750INV module allows for an easy-to-use, hardwired interface in connection with the inverter. | ||

Accura 2750LCG performs two-way data transmission between Accura 2700M and Accura 2750LC[I]. Accura 2750LCG supports two ports to communicate with two Accura 2700M modules for redundancy. Accura 2750LCG supports two networks(2 ports per group) for communication with Accura 2750LC[I]. It supports communication redundancy via ring connection of Accura 2750LC[I] using 2 ports in a single group. Up to 20 Accura 2750LC[I] modules can be connected in a single ring connection, and up to 40 modules can be connected in two ring connections. Accura 2750LCG supplies 24V DC control power to Accura 2750LC[I] through the communication cable. Due to the limit on the power supply of Accura 2750LCG, when the number of Accura 2750LC[I] modules exceeds 10 per network group, one Accura 2750LC POW module should be additionally connected to the rear of Accura 2750LC[I] to operate up to 20 modules per group. |

Accura 2750LC[I] is the digital control module for the LOP[Local Operating Panel] that substitutes the existing LOPs consisting of the push button, lamp, selection switch, and current meter. Accura 2750LC performs motor control commands at the field and displays the operational status and measurement data on the motor via communication with Accura 2700M through Accura 2750LCG. Along with the functions of Accura 2750LC, Accura 2750LCI provides the INVERTER/BYPASS buttons on the front for the operation of the inverter. In the existing LOPs, once the RUN/STOP command is executed by pressing the push button, it is sent to Accura 2750PC through the signal cable connected with the contact point of the push button and the digital input of the corresponding Accura 2750PC. However, when pressing the RUN/STOP button on Accura 2750LC[I], the control command is sent to Accura 2700M through Accura 2750LCG. Accura 2700M performs the RUN/STOP command by sending the command to Accura 2750PC of the corresponding motor-unit through communication. This communication method is beneficial since a single communication cable replaces multiple signal cables connecting the MCC to the LOP at the existing system. It allows users to easily identify the disconnection and short-circuit state of the cable. Accura 2750LCG supports communication redundancy through ring connection using 2 communication ports on Accura 2750LC[I]. |

One Accura 2700M module and multiple Accura 2750P[C] modules are connected through communication. The Category 5e FTP, STP, or SFTP Ethernet cable is used for high reliability and convenience. Accura 2700M should be connected with Accura 2750P[C] modules of individual motor units with the Daisy-chain method. However, the Unit-Socket is provided for convenience in installing communication cables and withdrawing motor units. A single Ethernet cable is also used to connect the Unit-Socket and Accura 2750P[C]. It makes it easy to disconnect the communication line when withdrawing motor units. | ||
