AL075 Encoder absolute number of revolutions is in error
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.
AL077 Encoder internal error
Trigger condition
and cause
Encoder internal error (internal computing error).
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.
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.
AL079 Encoder parameter setting incomplete
Trigger condition
and cause
The servo drive is not cycled after the encoder parameter is written to the encoder,
so the parameter value is not updated.
Checking method
and corrective action
Check if the encoder parameter is written. If so, cycle power to activate the
parameter.
How to clear the
alarm?
Cycle power on the servo drive.
AL07A Encoder Z phase position is lost
Trigger condition
and cause
Encoder Z phase position is in error.
Checking method
and corrective action
Send your servo motor back to the distributor or contact Delta.
