4.2.41 Communication error "E.OPT" operation selection (Pr. 500 to Pr. 502)
Pr. 500 "communication error execution waiting time"
Pr. 501 "communication error occurrence count indication"
Pr. 502 "error-time stop mode selection"
Use Pr. 500 to Pr. 502 to set the "E.OPT" operation.
(1) Pr. 500 "communication error execution waiting time"
You can set the waiting time from occurrence of a communication line fault to
communication error indication "E.OPT".

Communication error "E.OPT"
Indication output
Time set in Pr. 500
If a communication line fault still persists after the time set in Pr. 500 has elapsed, it is
recognized as a communication error and the communication error indication "E.OPT"
is output.
If communication is restored to normal during the set time, operation is continued
without a communication error indication.
(2) Pr. 501 "communication error occurrence count indication"
You can display the cumulative number of communication line faults that occurred.
Write "0" to Pr. 501 to clear the communication error occurrence count.

At the time when a communication line fault occurs, one count is made in Pr. 501
"communication error occurrence count indication".
Note: The communication error occurrence count indication is temporarily stored in RAM.
As it is reflected to E
2
PROM per hour only, performing power-on reset or inverter
reset causes the last value stored in E
2
PROM to appear in the parameter.
