4.2.1

Selection of command source in Network operation mode (Pr.550)

• Either of the RS-485 terminals or the communication option can be specified for the command source in the Network

operation mode.

• For example, whether or not the communication option is mounted, set Pr.550 ="1" to write parameters from or input the

start and frequency commands via RS-485 terminals in the Network operation mode.

NOTE

• In the initial setting, "9999" (communication option automatic recognition) is set for Pr.550. Thus, if the communication

option is mounted, parameters cannot be written or the start and frequency commands cannot be sent by

communications that use the RS-485 terminals. (Monitoring or parameter reading can be performed.)

4.2.2

• Any of the PU connector, RS-485 terminals, or USB connector can be specified as the command source in the PU operation

mode.

• Set Pr.551 ="1" to use communication connected to the RS-485 terminals to write parameters or execute start and

frequency commands in the PU operation mode.

NOTE

• When Pr.550 ="1" (NET mode RS-485 terminals) and Pr.551 ="1" (PU mode RS-485 terminals), the PU operation

mode has a precedence. For this reason, if the communication option is not mounted, switching to the Network

operation mode is not longer possible.
