AL06F The absolute position is not established
Checking method
and corrective action
If the issue persists after you cycle power on the servo drive and re-establish the
absolute origin coordinate, contact your local distributor or technician.
How to clear the
alarm?
Cycle power on the servo drive and re-establish the absolute origin coordinate.
AL071 Number of revolutions of the encoder is in error
Trigger condition
and cause
Condition: the number of revolutions of the encoder is in error.
Cause: the internal signal of the encoder is abnormal causing error in the number
of revolutions of the encoder.
Checking method
and corrective action
If you executed DI.ARST but the issue persists, send your servo motor back to the
distributor or contact Delta.
How to clear the
alarm?
DI.ARST
AL072 Encoder overspeed
Trigger condition
and cause
1.
When the encoder is powered by the servo drive: over 8,800 rpm.
2.
When the encoder is powered by the battery: over 10,000 rpm.
3.
Voltage level of the battery is too low.
Checking method
and corrective action
1.
Check if the motor is properly grounded. Make sure the power cable (green
end) is grounded to the servo drive heat sink.
2.
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.
3.
Use a shielded cable for the encoder, pull out the shielded mesh, and ground
it.
4.
Check the motor speed and make sure it is within the rated range.
5.
Measure the battery voltage to see if it is below 3.1V.
6.
Check if the battery wiring has poor contact.
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.
AL070 Encoder did not complete the read / write procedure
Trigger condition
and cause
Reading and writing commands are not complete.
Checking method
and corrective action
Check if the wiring is correct and firmly connected. If not, correctly connect the
wiring again. Contact Delta if this error persists.
How to clear the
alarm?
Cycle power on the servo drive.
