AL023：Early warning for overload
Causes Checking Method Corrective Actions
Early warning for
overload
1. Check if it is used in overload
condition.
2. Check if the value of parameter
P1-56 is set to small.
1. Please refer to the corrective
actions of AL006.
2. Please increase the setting
value of parameter P1-56. Or
set the value over 100 and
deactivate the overload warning
function.
AL024：Encoder initial magnetic field error
Causes Checking Method Corrective Actions
The initial magnetic field
of the encoder is in error
(Signal, U, V, W of the
encoder magnetic field
is in error.)
1. Check if the servo motor 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.
If issue persists, please send the
drive back to the distributors or
contact with Delta.
AL025：The internal of the encoder is in error
Causes Checking Method Corrective Actions
The internal of the
encoder is in error.
(The internal memory
and the internal counter
are in error)
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.
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 issue persists, please send the
drive back to the distributors or
contact with Delta.
When power on, the
motor operates because
of mechanical inertia or
other causes
When power on, please make sure
the motor shaft stands still and will
not operate.
When power on, please make sure
the motor shaft stands still and will
not operate.
AL026：Unreliable internal data of the encoder
Causes Checking Method Corrective Actions
The encoder is in error.
(Errors occur in the
internal data for three
times continuously)
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.
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 issue persists, please send the
drive back to the distributors or
contact with Delta.
