Communication functions (Pr. 117 to Pr. 124)
<Setting>
To make communication between the personal computer and inverter, the initial settings 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.
CAUTION
Always reset the inverter after making the initial settings of the parameters. Communication is disabled
unless the inverter is reset after the communication-related parameter values have been changed.

Set the permissible number of retries at occurrence of data receive
0 to 10 error. If the number of consecutive errors exceeds the permissible
value, the inverter will come to an alarm stop (E. PUE).
If a communication error occurs, the inverter will not come to an alarm
1
stop. At this time, the inverter can be coasted to a stop by MRS or
9999 RESET input.
(65535) During a communication error (H0 to H5), the minor fault signal (LF) is
given to the open collector output. Allocate the used terminal with any
of Pr. 190 to Pr. 192 and Pr. 195 (output terminal function selection).
