(7) Pr. 343 Communication error count
You can check the cumulative number of communication errors.
(8) Output signal LF "alarm output (communication error warnings)"
During a communication error, the alarm signal (LF signal) is output by open collector output. The LF signal
can be assigned to the output terminal using any of
Pr. 190 to Pr. 196 (output terminal function selection)
.

Read/write
Being 2 bytes in length, the data is stored as
"H00

". Refer to the lowest 1 byte for the fault
code.
Performing write using the register 40501 batch-
clears the faults history. Set any value as data.

CAUTION
The number of communication errors is temporarily stored into the RAM. As it is not stored into the EEPROM, performing
a power supply reset or inverter reset clears the value to 0.
CAUTION
Changing the terminal assignment using
Pr. 190 to Pr. 196 (output terminal function selection)
may affect the other functions. Make
setting after confirming the function of each terminal.
