AL005 Regeneration error
Trigger condition
and causes
Condition: an error occurs during regeneration.
Causes:
1. You selected a wrong regeneration resistor or the external regeneration
resistor is not connected.
2. P1.053 (regenerative resistor capacity) is not set to 0 when the
regenerative resistor is not connected
3. Parameter setting error (P1.052, P1.053).
Checking methods
and corrective
actions
1. Re-calculate the value for the regenerative resistor and reset the value
of P1.052 and P1.053. If you cannot clear the alarm, please send the
servo drive back to Delta.
2. Set P1.053 to 0 if not using a regenerative resistor.
3. Correctly set the parameters for the regenerative resistor, (P1.052) and
the
regenerative resistor capacity
(P1.053).

AL006 Overload
Trigger condition
and causes
Condition: overload of motor and servo drive.
Causes:
1. The load is over the rated range and the servo drive is in a persistent
overload condition.
2. The control system parameter is wrong.
3. Incorrect wiring of motor and encoder.
4. Encoder malfunction.
Checking methods
and corrective
actions
1. Set P0.002 to 11 to monitor the servo drive status. Check if the average
torque [%] is continuously over 100%. If so, please increase the motor
capacity or reduce the load. Refer to Load and operation time in
Appendix A for more details.
(A) Check if there is any mechanical vibration.
(B) Acceleration/deceleration constant is set too high.
2. Check if the wiring of UVW and the encoder cables is correct.
3. Send the servo drive back to distributors or contact Delta.
