ASDA-B3 Troubleshooting
13-13
13
AL011 Encoder error
Checking method
and corrective action
1.
Check if the wiring follows the instructions in the user manual. If not, connect
the wiring correctly.
2.
Check the connection between CN2 and encoder connector. If the connector
is loose, reconnect it to CN2.
3.
Check for the encoder cable and connector which connect the motor and
CN2 of the servo drive to see if there is any poor wiring or damaged wires.
If so, replace the connector and cable.
4.
Check the communication error rate by setting P0.002 to -80. If this value
continues to accumulate, it means there is interference. Check the following
items:
(a)
Check if the motor is properly grounded. Make sure the power cable
(green end) is grounded to the servo drive heat sink.
(b)
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.
(c)
Use a shielded cable for the encoder, pull out the shielded mesh, and
ground it.
5.
If you took all corrective actions but the issue persists, replace the motor.
How to clear the
alarm?
Cycle power on the servo drive.
AL012 Calibration error
Trigger condition
and cause
Condition: the calibration value exceeds the allowable value during electronic
calibration.
Cause:
1.
The analog input contact is not correctly returned to zero.
2.
The detection device is damaged.
Checking method
and corrective action
1.
Check if the voltage level at the analog input contact is the same as the
ground potential.
2.
Reset the power supply. If the issue persists, send your servo drive back to
the distributor or contact Delta.
How to clear the
alarm?
Remove the connection cable for CN1 and then execute auto calibration.
