6 Handling of Errors and Maintenance
6 - 6 EtherCAT Communication Unit USER’S MANUAL (I574-E1)
6-3 Application Errors
The statuses change as follows when an error is detected in the unit or inverter.
6-3-1 Error Statuses
Function Status when error occurs
Status display An error is notified with bit 3: Fault or bit 7: Warning of the Status object (5100 hex)
and bit 3: Fault or bit 7: Warning of the Statusword object (6041 hex).
When a trip occurs for the inverter, Fault bit it turned ON, and when a warning
occurs for the inverter, Warning bit is turned ON.
To cancel the error, eliminate the cause and set bit 7: Fault reset of 5000 hex Com-
mand or bit 7: Fault reset of 6040 hex Controlword to ON.
Error code display The error codes are notified to the object 603F hex. Read with the SDO.
To check the error that occurred for the inverter, check the inverter front panel, or
read object 3000 hex sub-index 13 hex with the SDO.
Diagnosis history Errors that were detected in the unit and inverter are stored in the Diagnosis history
object (10F3 hex) (up to 8 errors).
If a trip occurred for the inverter, check the trip history of the inverter.
6-3-2 Error Code List
Error code Meaning Possible correction
5300 hex Error in the communication unit
and inverter connection
Check that the Communication Unit is mounted correctly
onto the inverter.
The Communication Unit is faulty. Replace the Communica-
tion Unit.
A connection error occurred because a trip reset was per-
formed with the inverter. Set the inverter C102 to 3: Trip
reset only, and turn the power supply OFF and ON again.
A connection error occurred because an initialization or
mode change was performed with the inverter. Turn the
inverter power supply OFF and ON again.
6341 hex PDO setting error A set value in PDO mapping is invalid. Check the value of
object 5200 and the AL Status code, and then review the PDO
mapping settings.
6331 hex EEPROM data error An error was detected in data inside EEPROM when the
power supply was turned ON. Replace the Communication
Unit.
The Diagnosis history cannot be saved because the
EEPROM has reached the end of its service life. There is
no effect on operations, but if you want to use the Diagnosis
history, replace the unit.
FF00 hex A warning occurred for the
inverter
Eliminate the cause and set bit 7: Fault reset of Command
(5000 hex) or bit 7: Fault reset of Controlword (6040 hex) to
ON.
FF01 hex A trip occurred for the inverter Eliminate the cause and set bit 7: Fault reset of Command
(5000 hex) or bit 7: Fault reset of Controlword (6040 hex) to
ON.
