Start command source and frequency command
source during communication operation
The start and frequency commands from an external device can be made valid when using the RS-485 terminals or the
communication option. The command source in the PU operation mode can also be selected.

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.)

Setting range
0 Start command source is communication.
1 Start command source is external.
Frequency command source is
0
communication.
1 Frequency command source is external.
Frequency command source is external.
(When there is no external input, the
2 frequency command via communication
is valid, and the frequency command from
terminal 2 is invalid.)
The communication option is the
0 command source when in the NET
operation mode.
The RS-485 terminals are the command
1
source when in the NET operation mode.
Communication option is recognized
automatically.
Normally, the RS-485 terminals are the
9999 command source. When the
communication option is mounted, the
communication option is the command
source.
The RS-485 terminals are the command
1
source when in the PU operation mode.
The PU connector is the command
2
source when in the PU operation mode.
The USB connector is the command
3
source when in the PU operation mode.
USB automatic recognition
Normally, the PU connector is the
9999 command source. When the USB is
connected, the USB connector is the
command source.
