Value
Specify the inverter station number.
Set the inverter station numbers when two

0 to 31
or more inverters are connected to one
personal computer.
Set the communication speed.
The setting value × 100 equals the
48, 96, 192,

192
communication speed.

For example, the communication speed is
19200bps when the setting value is "192".

Set the permissible number of retries at
occurrence of a data receive error.
0 to 10
If the number of consecutive errors
exceeds the permissible value, the inverter
