AL027 Encoder internal reset error
Trigger condition
and cause
Condition: encoder reset error.
Cause: encoder reset.
Checking method
and corrective action
1.
Check if the encoder signal cable is firmly connected.
2.
Check if the power supply for the encoder is stable and make sure to use a
shielded cable.
3.
Check if the operating temperature is over 95°C (203°F). Identify the cause for
the high temperature and do not restart the operation before the temperature
drops to the allowable range.
If the issue persists, send your servo motor back to the distributor or contact Delta.
How to clear the
alarm?
Cycle power on the servo drive.
AL028 Battery voltage error or encoder internal error
Trigger condition
and cause
Condition: battery voltage is higher than the specification (> 3.8V) or the encoder
signal is in error.
Cause:
1.
Voltage level of the battery is too high.
2.
Encoder internal error.
Checking method
and corrective action
1.
Check if there is a charging circuit. Avoid incorrect wiring. If Pin 1 (5V) of CN2
is connected to BAT+ of the encoder connector, it means the power (5V) of the
servo drive is being charged to the battery.
2.
Check if the battery is correctly installed (voltage > 3.8V).
3.
Check if the motor is properly grounded. Make sure the power cable (green
end) is grounded to the servo drive heat sink.
4.
Check if the connection for the encoder signal cable is normal. Make sure the
encoder signal cable is separated from the power supply or any high-current
cables to avoid interference.
5.
Use a shielded cable for the encoder, pull out the shielded mesh, and ground
it.
If the issue persists, send your servo drive and motor back to the distributor or
contact Delta.
