NOTE
• Always reset the inverter after making the initial settings of the parameters. After changing the communication-related
parameters, communication cannot be made until the inverter is reset.
5.11.4 Mitsubishi inverter protocol (computer link
communication)
Parameter setting and monitoring, etc. are possible by using the Mitsubishi inverter protocol (computer link communication) via
the PU connector on the inverter.
Setting
Initial value
range
Specify the inverter station number.
0 0 to 31 Enter the inverter station numbers when two or more inverters are
connected to one personal computer.
48, 96, 192, Select the communication speed.
192 384, 576, The setting value × 100 equals the communication speed.
768, 1152 For example, enter 192 to set the communication speed of 19200 bps.

Set the permissible number of retries for unsuccessful data reception.
0 to 10 If the number of consecutive errors exceeds the permissible value, the
inverter output will be stopped.

error occurs.
0 PU connector communication is disabled.
Set the interval of the communication check (signal loss detection)
0.1 to 999.8 time
9999
s If a no-communication state persists for longer than the permissible
time, the inverter output will be shut off.
9999 No communication check (signal loss detection)
