Inverter station number specification.
0 0 to 31 Set the inverter station numbers when two or more
inverters are connected to one personal computer.
Set the communication speed.
48, 96, 192, The setting value × 100 equals the communication
192 384, 576, 768, speed.
1152 For example, if 192 is set, the communication speed is
19200 bps.

Set the communication check time interval.
If a no-communication state persists for the
9999 0.1 to 999.8 s
permissible time or longer, the inverter output is shut
off. (The operation depends on the Pr.502 setting.)
9999 No communication check (signal loss detection)
Set the delay between data transmission to the
0 to 150 ms
inverter and response.
9999 Set with communication data.
RS-485 terminals are the command interface enabled

USB automatic recognition
Basically, the operation panel (PU connector) is the
9999
command interface. When the USB connector is used,
it is the command interface.
