These parameters are communication parameters that are not cleared when parameter clear (all
clear) is executed from RS-485 communication.
(Refer to section 6.19 for RS-485 communication).

Description
Set the inverter station numbers when two
or more inverters are connected to one
personal computer.
When "1" (Modbus®-RTU protocol) is set in
Pr. 549, the setting range within parenthesis
is applied.
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".
Stop bit length: 1 bit
data length: 8 bits
Stop bit length: 2 bits
data length: 8 bits
Stop bit length: 1 bit
data length: 7 bits
Stop bit length: 2 bits
data length: 7 bits
Without parity check
(for Modbus®-RTU: stop bit length: 2bits)
With odd parity check
(for Modbus®-RTU: stop bit length: 1 bits)
With even parity check
(for Modbus®-RTU: stop bit length: 1 bits)
If the number of consecutive errors exceeds
the permissible value, E.PUE (computer
link)/E.ESR (Modbus®-RTU) will cause 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.
