Selection Of The Command Source Of The Pu Operation Mode - Mitsubishi Electric A800-E Instruction Manual

(D) Operation command and frequency command
Selection of the command source of the PU operation mode (Pr.551)
• Any of the PU connector, Ethernet connector, or USB connector can be specified for the command source in the PU
operation mode.
• In the PU operation mode, set Pr.551 = "5" to write parameters or input the start and frequency commands via the Ethernet
connector. Set Pr.551 = "3 or 9999" to use the USB connector.
NOTE
• When Pr.550 = "5" (NET operation mode, Ethernet connector) and Pr.551 = "5" (PU operation mode, Ethernet connector),
the PU operation mode has precedence.
• Changed setting values are enabled at power-ON or inverter reset.


If the communication option is not mounted, switching to the NET operation mode is not possible.

When Pr.551 = "9999", the priority of the PU command source is defined as follows: USB connector > PU connector.

When the CC-Link IE Field Network Basic is used, the NET operation mode has precedence. However, the Ethernet connector is not used as
the command source if a communication option is installed while Pr.550 = "9999".
