DI.ARST or cycle power on the servo drive.
Condition: abnormal vibration occurred in the encoder.
Cause: the internal signal or mechanical part of the encoder is abnormal,
so the encoder returns a warning signal.
Check if the motor vibration range is within the warning range (2.0 to 2.5 G). If the
vibration is below the warning range but the alarm still occurs, send your servo
motor back to the distributor or contact Delta.
DI.ARST or cycle power on the servo drive.
Condition: the number of revolutions of the absolute motor (P0.051) exceeds half
the number of revolutions of the encoder resolution.
The number of revolutions of a Delta motor is -32768 to +32767.

specifications.
Cause: motor's rotation cycle exceeds the allowable range.
Check if the motor's number of revolutions during operation is within the
1.
specified range. If not, re-establish the absolute origin position.
Make sure you have enabled the function for preventing rotary axis position

loss when an overflow occurs. If it is disabled, set P2.069.Z to 1 to enable the
function.
Re-establish the absolute origin position.
Condition: the encoder temperature is over the warning level of 85°C (185°F),
but still under 100°C (212°F), which is within the protective range.
Cause: encoder temperature warning (85°C to 100°C).
Set P0.002 to -124 to read the encoder temperature and check if it matches the
motor temperature. If the temperature is too high, improve the heat dissipation or
decrease the operating temperature. If the temperature difference between the
encoder and motor is over 30°C (86°F), send the servo motor back to Delta.
