AL085：Regeneration Error
Causes
Choose wrong
regenerative resistor or
does not connect to
external regenerative
resistor
Parameter P1-53 is not
set to zero when the
regenerative resistor is
not in use.
Wrong parameter setting
AL095： The servo drive does not connect to external regenerative resistor
Causes
The input of regenerative
resistor capacity is over 0
and the servo drive does
not connect to external
regenerative resistor
AL099：DSP firmware upgrade
Causes
Upgrade DSP firmware
AL111：CANopen SDO receives overflow
Causes
SDO Rx Buffer overflow
(receives more than two
SDOs within 1ms)
AL112：CANopen PDO receives overflow
Causes
PDO Rx Buffer overflow
(receives more than two
PDOs of COBID within
one millisecond)
Revision February, 2017
Checking Method
Check the connection of
regenerative resistor.
Check if parameter P1-53 of
regenerative resister is set to zero.
Check the setting value of
parameter P1-52 and P1-53.
Checking Method
1. Check if it is connected to
regenerative resistor.
2. Check if the setting value of P1-
53 is 0.
Checking Method
Check if the firmware is upgraded.
Checking Method
Check if the servo drive receives
(sends) more than one SDO within
1ms.
Checking Method
Check if the servo drive receives
(sends) more than one PDO of
COBID within 1ms.
Corrective Actions
Calculate the value of the
regenerative resistor again and
correctly set the value of P1-52 and
P1-53. If issue persists, please
send the drive back to the
distributors or contact with Delta.
Set parameter P1-53 of
regenerative resistor to zero when
it is not applying.
Correctly reset the value of P1-52
and P1-53.
Corrective Actions
1. If wish to apply regenerative
brake, please connect to
external regenerative resistor.
Then, check if the setting of P1-
53 is correct.
2. If not applying to regenerative
brake, please set P1-53 to 0.
3. If issue persists after
conducting the above two
steps, please send the drive
back to distributors or contact
with Delta.
Corrective Actions
Firstly set P2-08 to 30. Then set
P2-08 to 28, the alarm will be
cleared when re-power on.
