Mitsubishi Electronics FR-A700 Manuel D’Utilisation

Use the following parameters to perform required settings for communication between the inverter and personal
computer.

There are two different communications: communication using the PU connector of the inverter and
communication using the RS-485 terminals.
You can perform parameter setting, monitor, etc. from the PU connector or RS-485 terminals of the inverter
using the Mitsubishi inverter protocol (computer link communication).
To make communication between the personal computer and inverter, initialization of the communication
specifications must be made to the inverter.
Data communication cannot be made if the initial settings are not made or there is any setting error.

0

0 to 31

Specify the inverter station number.
Set the inverter station numbers when two or 
more inverters are connected to one 
personal computer.

192

48, 96, 192, 384

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".

Set the permissible number of retries at
occurrence of a data receive error. If the
number of consecutive errors exceeds the
permissible value, the inverter trips.

If a communication error occurs, the inverter
will not trip.

If a no-communication state persists for
longer than the permissible time, the inverter
trips.
