interruption
AL021
: Error in the motor collision
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
interruption
Check if the wire is loose.
Connect the wire correctly.
AL022
: Exceeding the upper limit for the motor temperature
Reason for abnormality
Check for abnormality
Handling of abnormality
The motor temperature is
over 90
℃
.
Check if the motor temperature is
too high.
Reduce the motor temperature.
AL023
: Exceeding the upper limit for the encoder temperature
Reason for abnormality
Check for abnormality
Handling of abnormality
Encoder temperature
exceeding 85
℃
Check if the encoder temperature
is too high.
Lower the encoder temperature.
AL025
: Overheated encoder
Reason for abnormality
Check for abnormality
Handling of abnormality
Encoder temperature
exceeding 65
℃
Check if the encoder temperature
is too high.
Lower the encoder temperature.
AL026
: Overcurrent output by the servo
Reason for abnormality
Check for abnormality
Handling of abnormality
Abnormality in the setting
of the control parameter
The control or gain value is set
too high.
The value is reset to the initial
value. It will be set and calibrated
again.
Abnormality in the
control command
Check if the input command is in
a state of high severity.
Modify the input command or turn
on the filter function.
AL027
: Regeneration overload
Reason for abnormality
Check for abnormality
Handling of abnormality
Error in the parameter
setting
Check the parameter for the
resistor capacity and the resistor
parameter.
Reset the parameter value.
The capacity of
regenerative resistor is
insufficient.
Check if the deceleration time is
too short or if the capacity of the
regenerative resistor is too low.
Increase the deceleration time or
attach the regenerative resistor with
higher watts.
AL050
: Low voltage
Reason for abnormality
Check for abnormality
Handling of abnormality
Input voltage of the main
circuit below the
allowance
Measure the input power by the
voltmeter to see if it is consistent
with the specified value.
Use the adequate power supply or
cascade the voltage stabilizer.
AL051
: Emergency stop
Reason for abnormality
Check for abnormality
Handling of abnormality
Emergency stop switch
pressed
Check the switch status.
Turn on the emergency stop switch.
AL052
: Abnormality in the CCW-limit
Reason for abnormality
Check for abnormality
Handling of abnormality
CCW-limit switch pressed Check the switch status.
Turn on the CCW-limit switch.
