AL010 : Abnormality in the calibration
Reason for abnormality
Check for abnormality
Handling of abnormality
Analog Input contact not
returned to zero
Measure if the voltage level of the
analog input contact is equivalent
to the ground potential.
The analog input contact is
grounded correctly.
Damage of the detecting
element
Detection of power reset
If any abnormality still occurs,
return the element to the factory for
repair.
AL011 : IGBTOverheated module
Reason for abnormality
Check for abnormality
Handling of abnormality
Overheated drive
Check if the drive temperature is
too high.
Lower the drive temperature.
AL012 : Abnormality in the EEPROM
Reason for abnormality
Check for abnormality
Handling of abnormality
Memory damage
Return it to the dealer or factory
for repair.
AL015 : Ambient temperature too high
Reason for abnormality
Check for abnormality
Handling of abnormality
Ambient temperature of
the drive too high
Check if the drive temperature is
too high.
Lower the drive temperature.
AL017 : Error in the data reliability of the encoder
Reason for abnormality
Check for abnormality
Handling of abnormality
Abnormality in three data
entries of the encoder data
received by the drive in a
row.
1. Check if the motor is
grounded normally.
2. Check if the signal cable of
the encoder is entangled with
the line with the power or high
current. If not, the interference
source can be avoided.
3. Check if the mesh is used for
the filament of the encoder.
1. Make sure that the ground end
of the UVW connector is
connected to the heat
dissipation of the drive.
2. Check the wiring for the signal
cable of the encoder to prevent
it from entangling with other
lines.
3. Use the filament with mesh.
4. If the situation is not improved,
return the drive the factory for
repair.
AL018 : Overheated motor
Reason for abnormality
Check for abnormality
Handling of abnormality
The motor temperature is
over 75℃.
Check if the motor temperature is
too high.
Reduce the motor temperature.
AL019 : Error in the CRC communication
Reason for abnormality
Check for abnormality
Handling of abnormality
Error in RS-232/485
communication
Check if the signal cable is
interfered with.
Check the wiring for the signal
cable to prevent it from entangling
with other lines.
AL020 : Timeout of the serial communication
Reason for abnormality
Check for abnormality
Handling of abnormality
Inadequate setting of the
timeout parameter
Check the setting of timeout
parameter.
Set the parameter correctly.
Communication
Check if the wire is loose.
Connect the wire correctly.
