12-5-1 Troubleshooting Using Error Displays
35 00 FPGA WDT
Error
An FPGA error was
detected.
False detection due to a
data read error that was
caused by excessive
noise
If this event does not occur after
you cycled the power supply, use
the product continuously. It is sup-
posed that a temporary error
occurred due to a read error.
If this event occurs again, the hard-
ware is faulty. Replace the Servo
Drive.
Hardware failure
01 System Error A hardware error due to
the self-diagnosis and a
fatal software error were
detected.
False detection due to a
data read error that was
caused by excessive
noise
If this event does not occur after
you cycled the power supply, use
the product continuously. It is sup-
posed that a temporary error
occurred due to a read error.
If this event occurs again, a fatal
error exists. Replace the Servo
Drive.
A fatal software error
was detected.
Hardware failure
02 Self-diagno-
sis Error
An error was detected
by the self-diagnosis of
the safety function.
False detection due to a
data read error that was
caused by excessive
noise
If this event does not occur after
you cycled the power supply, use
the product continuously. It is sup-
posed that a temporary error
occurred due to a read error.
If this event occurs again, replace
the Servo Drive.
Hardware failure
36 00 Non-volatile
Memory Data
Error
An error of data saved
in the non-volatile mem-
ory was detected.
Power interruption or
noise occurred while
parameters other than
the safety were saved
Save data after setting the parame-
ter again, and cycle the power sup-
ply.
Power interruption or
noise occurred while the
motor identity informa-
tion was saved
Execute Motor Setup, and cycle the
power supply.
Power interruption or
noise occurred while
safety parameters were
saved
Clear the FSoE slave address, exe-
cute FSoE Enable Reset, and cycle
the power supply.
37 00 Non-volatile
Memory
Hardware
Error
An error occurred on the
non-volatile memory.
False detection due to a
data read error that was
caused by excessive
noise
After you cycled the power supply, if
this error occurs continuously
although the error is reset, the
non-volatile memory is faulty.
Replace the Servo Drive.
Non-volatile memory
failure
Error No.
