 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.)
