Inverters-FREQROL-A800 Plus Series FREQROL-A800 Plus Liquid cooled type

FR-A800 Plus Liquid cooled type

Release of the new liquid cooled type inverter, FR-A800-LC

Coolant is used for cooling the inside of the inverter. Liquid cooling enables new applications in the environments where heat is difficult to be dissipated.

Features

  • Effective solution for downsizing of the enclosure
    A smaller enclosure can be used since the quantity of the heat dissipated in the enclosure is reduced.
  • Dedicated monitoring functions
    A sensor (flow switch) is attached at the inlet of coolant to send a signal to the inverter. When the coolant flow rate decreases, a warning is output, enabling quick, direct detection of system faults.
  • Lineup of 690 V class inverters
    The power supply voltage of 690 VAC is supported. A wider range of power supply voltage is covered.
  • The following functions (protocols) are available via general-purpose Ethernet communication.
  • CC-Link IE Field Network Basic
  • MELSOFT / FA product connection
  • SLMP*1
  • MODBUS/TCP
  • *1SLMP is a common protocol for seamless communication between applications. Users do not have to be concerned with network layers or boundaries.
  • *2MELSOFT / FA product connection, SLMP, etc.

What is CC-Link IE Field Network Basic?

CC-Link IE Field Network Basic is a new application of the lineup for CC-Link IE (Ethernet-based integrated network). CC-Link IE enables seamless data transfer between network layers, from higher-order information systems to lower-order field systems, which contributes to the visualization of the production data.

  • Cyclic communication (communication speed:100 Mbps)
  • Integrated Ethernet network in combination with the TCP or UDP IP connection*2 (no need for dedicated control wiring)
  • Simple and inexpensive system construction by general-purpose Ethernet without installing any plug-in option
  • Remote monitoring

The FR-A800-E-LC inverter can be remotely operated via Ethernet using FR Configurator2, which will be upgraded soon. Parameter setting, monitoring, and maintenance (for example, parts lifespan diagnosis) of the FR-A800-E-LC inverter is possible through network. Adjustment time and downtime of the inverter can be reduced.
