1. OUTLINE
1.4 Connection and parameter setting
• 700 series
*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 Pr.551 can be always written regardless of the operation mode.
NOTE
• Always reset the inverter after making the setting of the parameters. After you have changed the communication-related
parameters, communication cannot be established until the inverter reset.

Description
117 PU communication station number 0
0 to 31
(0 to 247)
*1*2
Set the inverter station number.
Set the inverter station numbers when two or more
inverters are connected to one personal computer.
122 PU communication check time interval 0
0
RS-485 communication can be made. Note that a
communication fault (E.PUE) occurs as soon as the
drive unit is switched to the operation mode with
command source.
0.1 to 999.8 s
Communication check (signal loss detection) time
interval.
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).
123 PU communication waiting time setting 9999
0 to 150 ms
Set the waiting time between data transmission to the
inverter and the response.
9999 Set with communication data.
331 RS-485 communication station number 0 0 to 31
Set the inverter station number.
Set the inverter station numbers when two or more
inverters are connected to one personal computer.
336
RS-485 communication check time
interval
0 s
0
RS-485 communication is enabled. However, the
inverter output is shut off if operation is changed to
NET operation mode.
0.1 to 999.8 s
Set the interval of communication check (signal loss
detection) time. If a no-communication state persists
for the permissible time or longer, the inverter output is
shut off.
9999 No communication check (signal loss detection)
337
RS-485 communication waiting time
setting
9999
0 to 150 ms
Set the waiting time between data transmission to the
inverter and response.
9999 Set with communication data.

0
The communication option is the command interface
enabled in the NET operation mode.
1
The RS-485 terminals are the command interface
enabled in the NET operation mode.
9999
Communication option is recognized automatically.
Basically, the RS-485 terminals are the command
interface. When the communication option is installed,
the communication option is the command interface.

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