Appendix 2 When Using The Communicaton Option - Mitsubishi FR-E540-0.4K-EC Instruction Manual

Appendix 2 When using the communication option.

Appendix 2 When using the communicaton option.

The extended functions for E.OPT error and E. 3 error have been added to this
instruction manual. (Pr. 500 to Pr. 502)
(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".

Number
500 0 to 999.8 s
Communication line status
Communication error "E.OPT"
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.

Count timing according to
communication line status
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
inverter reset causes the last value stored in E
parameter.
