Unit Replacement While Online - Mitsubishi Electric 800 Series Instruction Manual

3.1.3

Unit replacement while online

Connect an online communication connector to the CC-Link communication connector. The online communication connector
enables a unit replacement without interrupting the communication. Always connect the online communication connector to
connector 1 (front side) of the CC-Link communication connector. (Do not connect it to connector 2 (back side) of the CC-Link
communication connector. Doing so will cause a failure or breakage of the inverter and the connectors.)
Connect a one-touch connector plug with terminating resistor to the CC-Link communication connector of FR-A8NC at the end
station.
(A replacement while online is not available for the units, which are using the built-in terminating resistor selection switches.
(Refer to page 20.))
