<Setting>
To make communication between the personal computer and inverter, the communication specifications
must be set to the inverter initially. If initial setting is not made or there is a setting fault, data transfer cannot
be made.
Note: After making the initial setting of the parameters, always reset the inverter. After you have changed the
communication-related parameters, communication cannot be made if the inverter is not reset.

Set the permissible number of retries at occurrence of data receive error. If the
number of consecutive errors exceeds the permissible value, the inverter will come
to an alarm stop.

If a communication error occurs, the inverter will not come to an alarm stop. At this
time, the inverter can be coasted to a stop by MRS or RES input.
During an error, the light fault signal (LF) is given to the open collector output.
Allocate the used terminal with any of Pr. 190 to Pr. 195 (output terminal function
selection).
