Communication error count
You can check the cumulative number of communication errors.
(8) Output terminal LF "alarm output (communication error warnings)"
During a communication error, the alarm signal (LF signal) is output by open collector output. Assign the used terminal
using any of
Pr.190 to Pr.192 (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 error code.
Performing write using the register 40501 batch-clears

NOTE
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 drive unit reset clears the value to 0.
NOTE
The LF signal can be assigned to the output terminal using any of
Pr.190 to Pr.192
. Changing the terminal assignment
may affect the other functions. Set parameters after confirming the function of each terminal.
