Troubleshooting
AL060
Battery is under voltage.
9
The battery is replaced when
the control power is OFF.
After activating the absolute
function, the absolute
coordinate initialization has
not been completed.
Bad connection of the battery
power circuit.
AL061
Battery voltage is too low.
AL062
The multi-turn count of
absolute encoder exceeds
the maximum range: -32768
~ +32767.
AL067
Encoder temperature warning
(85 ~ 100°C)
9-12
The absolute position is lost
Causes
Check if the voltage of the battery is
lower than 2.8 V.
Do not replace or remove the battery
when the control power is OFF.
1. Install the battery.
2. Check the wiring between battery
box and the battery power cable of
the servo drive.
3. Check the wiring of the encoder.
1. Check the wiring of the encoder.
2. Check the wiring between battery
box and the servo drive.
Encoder under voltage
Causes
1. Check from the panel if the battery
voltage is lower than 3.1 V.
(tentative specification)
2. Check if the battery voltage is lower
than 3.1 V. (tentative specification )
The multi-turn count of absolute encoder
overflows
Causes
Check if the operation turn is within the
range from -32768 to +32767.
Encoder temperature warning
Causes
Set P0-02 to 120 (temperature display)
and check if the displayed value is the
same with the motor temperature.

Corrective Actions
After replacing the battery, conduct
homing again. Please refer to the
description of absolute coordinate
initialization in Chapter 10.
Conduct homing again. Please
refer to the description of absolute
coordinate initialization in Chapter
10.
Conduct homing again. Please
refer to the description of absolute
coordinate initialization in Chapter
10.
Connect or repair the wiring of the
battery so as to supply power to
the encoder. Conduct homing
again. Please refer to the
description of absolute coordinate
initialization in Chapter 10.
Corrective Actions
Replace the battery when the
control power is ON. This alarm
will be automatically cleared after
new battery is installed.
Corrective Actions
Conduct homing again. Please
refer to the description of absolute
coordinate initialization in Chapter
10.
Corrective Actions
1. Improve heat dissipation or
reduce operation load. The
temperature should be under
100°C.
2. If the displayed temperature of
the encoder is higher than the
motor's (over 30°C), please
send the motor back to
distributors.
