High flexibility by built-in PLC: The FR-A846 is easy to program with Mitsubishi Electric standard PLC software, which is available in FR Confiurator2. It is also possible to combine the PLC program with the Real time clock of the LU-08 operation panel.
Energy saving by 24 V control power supply: By connecting an external 24 V DC control power supply, the system can be operated even when the main power supply is turned off. Furthermore parameters can be set and network communication can be maintained with this power supply which facilitates safe maintenance. More energy saving can be achieved by using the automatic “stand by” function which switches off the drive main power supply. Capacitors and other devices are offline, so heat loss is reduced.
Improved system safety: The FR-A800 series has a two channel emergency stop for safe shutdown. This ensures safe operation in compliance with the European Machinery Directive without installation of another contactor. The FR-A846 thus conforms to the EN ISO13849-1/PLd cat. 3, EN 61508 and EN 61800-5-2 SIL2 standards.
Easy operation: The operation panel with the one touch Digital Dial allows direct access to all important parameters. Select the operation panel ideal for your needs. Choose either a LU operation panel with an LCD screen offering enhanced display functionality and a clock function, or a more economical DU operation panel with a 5-digit, 12-segment display. The FR-A846 series also allows the connection of a Mitsubishi Electric graphical operation terminal (GOT). Communication parameters for the HMI connection are automatically set as a batch. The GOT provides operators with an easy-to-follow and intuitively high resolution display and facilitates easy operation via a touch panel.
