Inverter station number specification
Set the inverter station numbers when two or more inverters
are connected to one personal computer.

PU communication
speed
192
48, 96, 192,
384
Set the communication speed.
The setting value x 100 equals the communication speed.
For example, the communication speed is 19200bps when
the setting value is "192".

retries
1
0 to 10
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.
9999 If a communication error occurs, the inverter will not trip.

RS-485 communication is enabled. Note that a
communication fault (E.PUE) occurs as soon as the inverter
is switched to the operation mode with control source.
0.1 to
999.8s
Communication check (signal loss detection) time interval
If a no-communication state persists for longer than the
permissible time, the inverter trips (depends on Pr. 502 ).
9999 No communication check (signal loss detection).
123
PU communication
waiting time setting
9999
0 to 150ms
Set the waiting time between data transmission to the inverter
and response.
9999 Set with communication data.
