Displaying and clearing the communication error count (Pr.501) (FR-E700 SC ENE)
●
The cumulative count of communication error occurrences can be displayed. Write "0" to clear
this cumulative count.
●
At the point of communication line error occurrence, Pr. 501 Communication error occurrence
count display is incremented by 1.
●
The cumulative count of communication error occurrences is counted from 0 to 65535. When the
count exceeds 65535, the displayed value is cleared and the counting starts over from 0 again.
Error reset operation selection at inverter fault (Pr. 349) (only FR-E700 SC ENE)
In the External operation mode or the PU operation mode, use this parameter to disable an error reset
command sent through the Ethernet network.

Fig. 6-124: Operation of the communication error occurrence counter
NOTE Communication error count is temporarily stored in the RAM. The error count is stored in E²PROM
only once per hour. If power reset or inverter reset is performed, Pr. 501 setting will be the one that
is last stored to E²PROM depending on the reset timing.
Pr. 349 Description
0 (initial value) Error reset is enabled independently of operation mode
1 Error reset is enabled only in the network operation mode
