The RS-485 terminals are the command interface
1
enabled in the PU operation mode.
The PU connector is the command interface enabled
2
in the PU operation mode.
The USB connector is the command interface in the
3
PU operation mode.
4 The operation panel is the command interface enabled
9999
in the PU operation mode.
The Ethernet connector is the command interface in

the PU operation mode.
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.

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.
0 Stop bit length 1 bit
1 Stop bit length 2 bits
1
10 Stop bit length 1 bit
11 Stop bit length 2 bits
0 Without parity check
2 1 With parity check at odd numbers
2 With parity check at even numbers
Set the permissible number of retries for unsuccessful
data reception. If the number of consecutive errors
0 to 10
exceeds the permissible value, the inverter output is
1
shut off.
Even if a communication error occurs, the inverter will
9999
not trip.
