*1 When "1" (MODBUS RTU protocol) is set in Pr.549, the setting range within parentheses is applied.
*2 When a value outside the setting range is set, the inverter operates at the initial value.
*3 Pr.549 = "0" (Mitsubishi inverter (Computer link) protocol).
*4 The setting is available only for the FR-F800 series.
*5 Pr. 551 is always write-enabled.
Initial
Setting range
value
Set the inverter station number.
0 to 31
0 Set the inverter station numbers when two or more
*1*2
(0 to 247)
inverters are connected to one personal computer.
RS-485 communication can be made. Note that a
communication fault (E.PUE) occurs as soon as the
0
drive unit is switched to the operation mode with
command source.
Communication check (signal loss detection) time
0
interval.
0.1 to 999.8 s If a no-communication state persists for the
permissible time or longer, the inverter output is shut
off. (The operation depends on the Pr.502 setting.)
9999 No communication check (signal loss detection).
Set the waiting time between data transmission to the
0 to 150 ms
inverter and the response.
9999 Set with communication data.
Set the inverter station number.
0 to 31 Set the inverter station numbers when two or more
inverters are connected to one personal computer.
RS-485 communication is enabled. However, the
0 inverter output is shut off if operation is changed to
NET operation mode.
Set the interval of communication check (signal loss
0 s
detection) time. If a no-communication state persists
0.1 to 999.8 s
for the permissible time or longer, the inverter output is
shut off.
9999 No communication check (signal loss detection)
Set the waiting time between data transmission to the
0 to 150 ms
inverter and response.

The communication option is the command interface
0
enabled in the NET operation mode.
The RS-485 terminals are the command interface
1
enabled in the NET operation mode.
9999
Communication option is recognized automatically.
Basically, the RS-485 terminals are the command
9999
interface. When the communication option is installed,
the communication option is the command interface.
The RS-485 terminals are the command interface
1
enabled in the PU operation mode.
The PU connector is the command interface enabled
2
in the PU operation mode.
The USB connector is the command interface in the
9999
3
PU operation mode.
USB automatic recognition
Basically, the operation panel (PU connector) is the
9999
command interface. When the USB connector is used,
it is the command interface.
