Chapter 10 Troubleshooting
AL060：The absolute position is lost
Causes
Battery under voltage
The battery is replaced
when the main power of
the servo drive is off.
After activating the
absolute function, the
absolute origin coordinate
has not been created.
Poor connection or
disconnection of the
battery power circuit
AL061：Encoder under voltage
Causes
Battery under voltage
AL062：The multi-turn of absolute encoder overflows
Causes
Motor's rotation cycle
exceeds the allowable
range.
Checking Method
Check if the voltage of the battery
is lower than 2.8V.
Do no change or remove the
battery when the power is OFF,
which is controlled by the servo
drive.
1. Install the battery.
2. Check the wiring between the
battery pack and the 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 the
battery pack and the power
cable of the servo drive.
Checking Method
1. Check if the voltage of the
battery on the panel is lower
than 3.1V (tentative
specification).
2. Measure if the voltage of the
battery is lower than 3.1V
(tentative specification).
Checking Method
Check if the motor's number of
turns while operating is within the
range between -32768 and
+32767.
Corrective Actions
After changing the battery, conduct
homing procedure again. Please
refer to the description of creating
the absolute origin coordinate in
Chapter 12.
Conduct homing procedure again.
Please refer to the description of
creating the absolute coordinate in
Chapter 12.
Conduct homing procedure. Please
refer to the description of creating
the absolute origin coordinate in
Chapter 12.
Connect or repair the wiring of the
battery so as to supply the power to
the encoder. Conduct homing
procedure again. Please refer to the
description of creating the absolute
origin coordinate in Chapter 12.
Corrective Actions
Do not change the battery when the
power is ON which is controlled by
the servo drive. After you change
the battery, AL061 will be cleared
automatically.
Corrective Actions
Conduct homing procedure again.
Please refer to the description of
