NOTE
• When a 32-bit parameter setting or monitor item is read and the value to be read exceeds HFFFF, HFFFF is returned.
 Pr.343 Communication error count
• The communication error occurrence count can be checked.
Parameter
343
NOTE
• The communication error count is temporarily stored in the RAM memory. The value is not stored in the EEPROM, and so is
cleared to 0 when power is reset and the inverter is reset.

Remarks
Being 2 bytes in length, the data is stored as H00○○.
Refer to the lowest 1 byte for the error code. (For details on error codes,
refer to the FR-E800 Instruction Manual (Maintenance).)
The fault history is batch-cleared by writing to register 40501.
Set any value as data.
Remarks
The inverter model can be read in ASCII code.
"H20" (blank code) is set for blank area.
Example) FR-E820-1:
H46, H52, H2D, H45, H38, H32, H30, H2D, H31, H20......H20
The capacity in the inverter model can be read in ASCII code.
Data is read in increments of 0.1 kW, and rounds down to 0.01 kW
increments.
"H20" (blank code) is set for blank area.
Example) 0.75K: " 7" (H20, H20, H20, H20, H20, H37)
