Chapter 10 Troubleshooting
AL023：Early warning for overload
Causes
Early warning for
overload
AL024：Encoder initial magnetic field error
Causes
The initial magnetic field
of the encoder is in error
(Signal, U, V, W of the
encoder magnetic field
is in error.)
AL025：The internal of the encoder is in error
Causes
The internal of the
encoder is in error.
(The internal memory
and the internal counter
are in error)
When power on, the
motor operates because
of mechanical inertia or
other causes
AL026：Unreliable internal data of the encoder
Causes
The encoder is in error.
(Errors occur in the
internal data for three
times continuously)
Revision February, 2017
Checking Method
1. Check if it is used in overload
condition.
2. Check if the value of parameter
P1-56 is set to small.
Checking Method
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.
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.
When power on, please make sure
the motor shaft stands still and will
not operate.

Corrective Actions
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.
Corrective Actions
If issue persists, please send the
drive back to the distributors or
contact with Delta.
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 issue persists, please send the
drive back to the distributors or
contact with Delta.
