AL005
: Overload
Reason for abnormality
Check for abnormality
Handling of abnormality
Continuous use while
exceeding the rated load
of the drive
Check if the motor operates in the
condition that the rated load is
above 100% for a long time
through the monitoring state
AVG-L.
Replace the old motor with the one
with higher watts or reduce the
load.
Inadequate setting of the
system parameter
1.
Check if the mechanical
system sways.
2.
The acceleration and
deceleration constant is set too
short.
Reset the value of switch
parameter.
Wrong wiring of the
motor and encoder
Check the UVW and encoder
wiring.
Install the wire correctly.
AL006
: Overspeed
Reason for abnormality
Check for abnormality
Handling of abnormality
Excessive variation of
speed command
Check if the speed command of
the upper input is abnormal.
Modify the command or turn on
the filter function.
Inadequate setting of the
system parameter
Check if the condition for the
overspeed warning (PD-53) is
insufficient.
Set the parameter value correctly.
AL007
: Abnormality in the pulse command
Reason for abnormality
Check for abnormality
Handling of abnormality
Frequency in the pulse
command above the rated
input frequency
Check the pulse frequency sent by
the upper controller.
Set the upper controller correctly.
AL008
: Excessive location error
Reason for abnormality
Check for abnormality
Handling of abnormality
The setting value of
parameter for position
control error set too low
Check the setting value of
parameter for position control
error (PD-54).
Increase the setting value of
parameter for position control error
(PD-54).
Control gain set too low
Check if the position and speed
gains are appropriate.
Calibrate the control gain again.
Torque limit too low
Check the torque limit value.
Set the torque limit correctly.
Excessive external load
Check the state of external load.
Reduce the load or replace the old
motor with the one with higher
watts.
AL009
: Abnormality in the encoder
Reason for abnormality
Check for abnormality
Handling of abnormality
Loose encoder wire
Check if the encode wire is loose.
Reattach the encoder wire.
Wrong wiring of the
encoder
Check if the encode wire is
consistent with the specifications
and definition.
Reattach the encoder wire.
Malfunction of encoder
An abnormality occurs in the
motor.
Replace the motor.
