The extended functions for E.OP3 error and E. 3 error have been added to this instruction manual. (Pr. 500 to
502)
1) Addition of Pr. 500 "communication error recognition waiting time"
You can set the waiting time from when a communication line fault occurs until it is recognized as a
communication error.

Communication error (OP3)
The communication line fault which still persists after the time set in Pr. 500 has elapsed is recognized as a
communication error.
When the fault is restored to normal communication within the set time, it is not regarded as a communication
error and operation continues.
2) Addition of Pr. 501 "communication error occurrence count display"
The cumulative number of communication error occurrences can be indicated. Write 0 to erase this
cumulative count.

At the point of communication line fault occurrence, Pr. 501 "communication error occurrence count display"
is incremented by 1.
Note: The communication error occurrence count is stored into RAM temporarily. Since this data is stored
in E
2
PROM at one-hour intervals, performing power-on reset or inverter reset may cause the Pr. 501
data to be the value stored in E
2
PROM the last time depending on the reset timing.
