Description
Specify the inverter station number.
Set the inverter station numbers when two or
more inverters are connected to one personal
computer.
Set the communication speed.
The setting value × 100 equals the
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.
If the number of consecutive errors exceeds
the permissible value, the inverter trips.
If a communication error occurs, the inverter
will not come to trip.
No PU connector communication
Set the communication check time interval.
If a no-communication state persists for longer
than the permissible time, the inverter trips.
No communication check
Set the waiting time between data transmission
to the inverter and response.
Set with communication data.

Parameter values written by communication are
written to the EEPROM and RAM.
Parameter values written by communication
are written to the RAM.
