Range Description
Inverter station number.
Set the inverter station numbers when two
or more inverters are connected to one
0 to 31
personal computer.
(0 to 247)
When "1" (Modbus-RTU protocol) is set in
Pr. 549, the setting range within parenthesis
is applied.
Communication speed.
The setting value X 100 equals the
48, 96,
communication speed.

(For example, 19200bps when the setting
value is 92)
0 Stop bit length: 1 bit data length: 8bit
1 Stop bit length: 2 bit data length: 8bit
10 Stop bit length: 1 bit data length: 7bit
11 Stop bit length: 2 bit data length: 7bit
Without parity check
0
(for Modbus-RTU: stop bit length: 2bit)
With odd parity check

(for Modbus-RTU: stop bit length: 1bit)
With even parity check
2
(for Modbus-RTU: stop bit length: 1bit)
Number of retries at data receive error
occurrence
0 to 10 If the number of consecutive errors
exceeds the permissible value, the inverter
will come to trip.
If a communication error occurs, the
9999
inverter will not come to trip.
RS-485 communication can be made. Note
that a communication error (E.PUE) occurs
0
as soon as the inverter is switched to the
operation mode with command source.
Communication check (signal loss
detection) time interval
0.1 to
If a no-communication state persists for
longer than the permissible time, the
999.8s
inverter will come to trip (depends on Pr.
502).
