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)
9-10
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

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 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
Delta.
