ASDA-A2
AL027：The internal of the motor is in error
Causes
The internal reset of the
encoder is in error.
AL028：Encoder voltage error or the internal of the encoder is in error
Causes
Battery voltage is too
high
The internal encoder is in
error.
AL029：Gray code error
Causes
Absolute position is in
error
AL030：Motor Crash Error
Causes
Motor Crash Error
10-16
Checking Method
1. Check if the servo is properly
grounded.
2. Check if the encoder cable
separates from the power supply
or the high-current circuit to avoid
the interference.
3. Check if the shielding cables are
used in the wiring of the
encoder.
Checking Method
1. Check if the charging circuit
exists in the servo drive.
2. Check if the battery is correctly
installed
1. Check if it is the absolute type
encoder.
2. Check if the servo is properly
grounded.
3. Check if the encoder cable
separates from the power supply
or the high-current circuit to avoid
the interference.
4. Check if the shielding cables are
used in the wiring of the encoder.
Checking Method
Re-power on to operate the motor
and check if the alarm will occur
again.
Checking Method
1. Check if P1-57 is enabled.
2. Check if P1-57 is set too small
and the time of P1-58 is set too
short.

Corrective Actions
1. Please connect the UVW
connector (color green) to the
heat sink of the servo drive.
2. Please check if the encoder
cable separates from the power
supply or the high-current circuit.
3. Please use shielding mesh.
4. If the situation is not improving,
please send the drive back to the
distributors or contact with Delta.
Corrective Actions
According to the procedure of Over
voltage to check. When corrective
actions are done, AL.028 will be
cleared automatically.
1. If the situation is not improving,
please send the drive back to the
distributors or contact with Delta.
2. Please connect the UVW
connector (color green) to the
heat sink of the servo drive.
3. Please check if the encoder
cable separates from the power
supply or the high-current circuit.
4. Please use shielding mesh. If the
situation is not improving, please
send the drive back to the
distributors or contact with Delta.
Corrective Actions
If the alarm occurs again, please
change the encoder.
Corrective Actions
1. If it is enabled by mistake, please
set P1-57 to zero.
2. According to the actual torque
setting, if the value is set too
small, the alarm will be triggered
by mistake. However, if the
value is set too big, it will lose
