EEPROM is not reset after DSP firmware is updated.
Check if the firmware is updated. If so, set P2.008 to 30 first and then set it to 28.
Next, cycle power on the servo drive. Contact Delta if this error persists.
Set P2.008 to 30 and then 28. Cycle power on the servo drive.
Condition: the parameter reset process is not complete.
Cause: an error occurred during the parameter reset process, so the reset
procedure could not be completed.
Check if the power is cut off during the reset process. Check the power wiring and
switch.
Set P2.008 to 30 and then 28. Cycle power on the servo drive.
Condition: suppose there are servo drive A, servo motor A, servo drive B, and
servo motor B. Servo drive A and servo drive B have established the absolute
origin positions with servo motor A and servo motor B respectively. In this case, if
you operate servo drive A with servo motor B, AL0A6 will be triggered.
Cause: the servo drive or servo motor is changed.
Re-establish the absolute origin positions.
Re-establish the absolute origin positions.
SDO Rx Buffer overflows (the servo drive receives more than two SDOs within
1 ms).
Check if the servo drive (master) receives or sends more than one SDO within
1 ms.
NMT: reset node, OD 6040h [Bit 7] (Fault reset), or DI.ARST.
PDO Rx Buffer overflows (the servo drive receives more than two PDOs of the
same COB-ID within 1 ms).
Check if the servo drive (master) receives or sends more than one PDO of the
same COB-ID within 1 ms.
