AL060 The absolute position is lost
Cleared after re-power on
Causes Checking Method Corrective Actions
Battery is under voltage. Check if the voltage of the battery is
lower than 2.8 V.
After replacing the battery, conduct
homing again. Please refer to the
description of absolute coordinate
initialization in Chapter 10.
The battery is replaced when
the control power is OFF.
Do not replace or remove the battery
when the control power is OFF.
Conduct homing again. Please
refer to the description of absolute
coordinate initialization in Chapter
10.
After activating the absolute
function, the absolute
coordinate initialization has
not been completed.
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.
Conduct homing again. Please
refer to the description of absolute
coordinate initialization in Chapter
10.
Bad connection of the battery
power circuit.
1. Check the wiring of the encoder.
2. Check the wiring between battery
box and the servo drive.
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.
AL061 Encoder under voltage
AL061 will be automatically cleared after new
battery is installed
Causes Checking Method Corrective Actions
Battery voltage is too low. 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 )
Replace the battery when the
control power is ON. This alarm
will be automatically cleared after
new battery is installed.
AL062
The multi-turn count of absolute encoder
overflows
Cleared after re-power on
Causes Checking Method Corrective Actions
The multi-turn count of
absolute encoder exceeds
the maximum range: -32768
~ +32767.
Check if the operation turn is within the
range from -32768 to +32767.
Conduct homing again. Please
refer to the description of absolute
coordinate initialization in Chapter
10.
AL067 Encoder temperature warning
Cleared by DI.ARST
Causes Checking Method Corrective Actions
Encoder temperature warning
(85 ~ 100°C)
Set P0-02 to 120 (temperature display)
and check if the displayed value is the
same with the motor temperature.
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.
