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 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
Delta.
