Description
Specify the inverter station
number. Set the inverter station
numbers when two or more invert-
ers 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 set-
ting 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 will
come to an alarm stop.
If a communication error occurs,
the inverter will not come to an
alarm stop.
No PU connector communication
Set the communication check time
interval. If a no-communication
state persists for longer than the
permissible time, the inverter will
come to an alarm stop.
No communication check
Set the waiting time between data
transmission to the inverter and
response.
Set with communication data.
