Cycle power on the servo drive and re-establish the absolute origin position.
Reading and writing commands are not complete.
Check if the wiring is correct and firmly connected. If not, correctly connect the wire
again. Contact Delta if this error persists.
Cycle power on the servo drive.
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.
If you executed DI.ARST but the issue persists, send your servo motor back to the
distributor or contact Delta.
DI.ARST
When the encoder is powered by the servo drive: over 8,800 rpm.
1.
When the encoder is powered by the battery: over 10,000 rpm.
2.
Voltage level of the battery is too low.
3.
Check if the motor is properly grounded. Make sure the ground end (green) of
1.
the power cable is grounded to the servo drive heat sink.
Check if the connection for the encoder signal cable is normal. Make sure the
2.
encoder signal cable is separated from the power supply or any high-current
cables to avoid interference.
Use shielded cable for the encoder cable. Pull out the wire mesh and have it
3.
correctly grounded.
Check the motor speed and make sure it is within the rated range.
4.
Measure the battery voltage to see if it is below 3.1V.
5.
Check if the battery wiring has poor contact.
6.
If the issue persists, send your servo motor back to the distributor or contact Delta.
Cycle power on the servo drive.
