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 encoder cable is
properly connected.
2. Check if the power supply is
stable.
3. Check if the operating
temperature is over 95 ℃ .
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.
AL028
: Encoder voltage error or the internal of the encoder is in error
Causes Checking Method Corrective Actions
Battery voltage is too
high.
4. Check if the charging circuit
exists in the servo drive.
5. Check if the battery is
correctly installed. ( Voltage >
3.8 V)
Please do the check according
to the procedure Over voltage.
When corrective actions are
done, AL028 will be cleared
automatically.
The internal encoder is
in error.
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.
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.
