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 Delta.
AL027:
The internal of the encoder is in error
Causes Checking Method Corrective Actions
The internal reset of
the encoder is 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 Delta.
AL028:
The internal of the encoder is in error
Causes Checking Method Corrective Actions
The encoder U, V, W
signals 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 Delta.
