AL061：Encoder under voltage
Causes Checking Method Corrective Actions
Battery under voltage
1. Check if the voltage of the
battery on the panel is lower
than 3.1 V (tentative
specification).
2. Measure if the voltage of the
battery is lower than 3.1 V
(tentative specification).
Do not change the battery when the
power is ON which is controlled by
the servo drive. After change the
battery, AL061 will be cleared
automatically.
AL062：The multi-turn of absolute encoder overflows
Causes Checking Method Corrective Actions
The operation distance
exceeds the range the
absolute encoder is able
to record
Check if the operation distance
exceeds the range, -32768 ~
+32767, the absolute encoder is
able to record.
Conduct homing procedure again.
Please refer to the description of
absolute coordinate initialization in
Chapter 12.
AL067： Encoder temperature warning
Causes Checking Method Corrective Actions
Encoder temperature
exceeds the warning
level. (But it is still within
the protective range85
~100℃.)
Check the setting: Set the value of
P0-02 to 120 to display the
temperature.
1. Improve heat dissipation or
reduce the loading of operation.
The temperature should be
lower than 100℃.
2. If the encoder’s temperature is
higher than the motor’s (more
than 30 degree). Please send
the motor back to the
distributors.
AL068：Absolute data transmitted via I/O is in error
Causes Checking Method Corrective Actions
Sequence error
1. Switch OFF DI ABSQ should
wait until DO ABSR is OFF.
2. Switch ON ABSQ should wait
until DO ABSR is ON.
Correct the reading sequence of I/O
Reading time out
Check if the time between
switching ON DO ABSR and
switching ON ABSQ exceeds
200ms.
After switching ON DO ABSR (the
absolute position data is ready),
read DO ABSD and switch ON DI
ABSQ within 200ms so that to
inform the servo drive data reading
is completed.
