Save error 1 (SE1) Keypad COPY error 1: keypad copy time-out
Action and Reset
Action level
“SE1” warning occurs when the keypad does not transmit the COPY command
to the drive, and does not transmit any data to the drive again in 10 ms at the
time you copy the parameters to the drive.
Action time 10 ms
Warning treatment parameter N/A
Reset method Manual reset
Reset condition Immediately reset
Record N/A
Cause Corrective Actions
Communication connection error
SE1: The causes of error are mostly communication problems between the
keypad and control board. Potential causes include communication signal
interference and the unacceptable communication command to the Slave.
It is not suggested to consider the communication quality at this time.
Check if the error occurs randomly, or only occurs when copying certain
parameters (the error displays on the upper right corner of the copy page). If you
cannot clear the error, please contact Delta.

Save error 2 (SE2) Keypad COPY error 2: parameter writing error
Action and Reset
Action level
“SE2” warning occurs when writing the parameters incorrectly at the time you
copy the parameters to the drive. For example, you copy the new firmware
version with added parameters to the drive with old firmware version.
Action time N/A
Warning treatment parameter N/A
Reset method Manual reset
Reset condition Immediately reset
Record N/A
Cause Corrective Actions
Add new parameters to the new
firmware version.
SE2: In this stage, the copied data has been transmitted to the Slave.
The Slave compares and processes the copied data, and then saves the data to
the Data ROM. During the process, the data error (should be attribution error)
may occur, or the data cannot be saved to EEPROM. At this time, the warning
occurs.
It is not suggested to consider the Data ROM at this time.
If you cannot clear the error, please contact Delta.
Malfunction caused by interference
Verify the wiring and grounding of the main circuit, control circuit and the
encoder for effective anti-interference performance.

IGBT over-heating
warning (oH1)
The AC motor drive detects over-heating of IGBT, and
over the protection level of oH1 warning. (When
Pr.06-15 is higher than the IGBT over-heating level, the
drive shows oH1 error without displaying oH1 warning.)
Action and Reset
Action level Pr.06-15
Action time
“oH1” warning occurs when IGBT temperature is higher than Pr.06-15 setting
value.
Warning treatment parameter N/A
Reset method Auto-reset
Reset condition
The drive auto-resets when IGBT temperature is lower than oH1 warning level
minus (–) 5°C.
