AL022 Main circuit power lack phase Cleared by DI.ARST
Causes Checking Method Corrective Actions
The main circuit power is
abnormal. 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. Correctly connect to the power. If
the alarm still exists, please send
the drive back to the distributors or
contact with Delta.
AL023 Early warning for overload Cleared by DI.ARST
Causes Checking Method Corrective Actions
Early warning for overload 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.
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.
AL024 Encoder initial magnetic field error Cleared after re-power on
Causes Checking Method Corrective Actions
Encoder initial magnetic field
error
(The magnetic field of the
encoder U, V, W signal is in
error.) 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.
If issue persists, please send the
drive back to the distributors or
contact with Delta.
AL025 The internal of the encoder is in error Cleared after re-power on
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 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.
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, the motor
operates because of
mechanical inertia or other
causes. When power on, please make sure the
motor shaft stands still and will not
operate.
When power on, please make
sure the motor shaft stands still
and will not operate.
