Save error 1
(SE1)
Keypad COPY error 1: keypad copy time-out
Action and Reset
Action condition
“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.

(SE2)
Keypad COPY error 2: parameter writing error

“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

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.
