AL022 Main circuit power lack phase
Causes
The main circuit power is
abnormal.
AL023 Early warning for overload
Causes
Early warning for overload
AL024 Encoder initial magnetic field error
Causes
Encoder initial magnetic field
error
(The magnetic field of the
encoder U, V, W signal 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.

Checking Method
Check if RST power cable is loose or no
power is applied. This alarm occurs
when drive of 1.5 kW (or below) is not
connected to three-phase power
supply; for drive of 2 kW (or above), the
alarm occurs when one single phase is
not connected to the power supply.
Checking Method
1. Check if the drive is used in
overload condition.
2. Check if the value of parameter
P1-56 is set to be too small.
Checking Method
1. Check if the servo motor is properly
grounded.
2. Check if the encoder cable is
separated from the power supply or
high-current cable to avoid
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
Correctly connect to the power. If
the alarm still exists, please send
the drive back to the distributors or
contact with Delta.
Cleared by DI.ARST
Corrective Actions
1. Please refer to the corrective
actions of AL006.
2. Please increase the setting
value of P1-56. Or set the
value to over 100 to
deactivate the function of
early warning for overload.
Cleared after re-power on
Corrective Actions
If issue persists, please send the
drive back to the distributors or
contact with Delta.
Cleared after re-power on
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 is separated from power
supply or the high-current
cable.
3. Please use cables with
shielding mesh.
4. If issue persists, please send
the drive back to the
distributors or contact with
Delta.
When power on, please make
sure the motor shaft stands still
and will not operate.
