AL044: Warning of Servo Drive function overload 
AL060: The absolute position is lost 
AL061: Encoder under voltage   
 
Causes  Checking Method Corrective Actions
Warning of Servo 
Drive function 
overload 
N/A 
Set P2-66 Bit 4 to 1 can disable 
the display of this alarm. 
Causes  Checking Method Corrective Actions
Battery undervoltage  Check if the voltage of battery is 
lower than 2.8V. 
fter changing the battery, 
conduct homing procedure 
again. Please refer to the 
description of absolute 
coordinate initialization in 
Chapter 12. 
Change the battery 
when the power is OFF 
which is controlled by 
the servo drive. 
Do not change or remove the 
battery power when the power is 
OFF which is controlled by the 
servo drive.   
Conduct homing procedure 
again. Please refer to the 
description of absolute 
coordinate initialization in 
Chapter 12. 
fter activating the 
absolute function, the 
absolute coordinate 
initialization has not 
been completed. 
6.  Install the battery. 
7.  Check the wiring between the 
battery pack and power cable 
of the servo drive. 
8. 3. Check the wiring of the 
encoder. 
Conduct homing procedure 
again. Please refer to the 
description of absolute 
coordinate initialization in 
Chapter 12. 
Bad connection of the 
battery power circuit. 
1. Check the wiring of the 
encoder. 
2. Check the wiring between the 
battery pack and the power 
cable of the servo drive. 
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 
absolute coordinate initialization 
in Chapter 12. 
Causes  Checking Method Corrective Actions
The voltage of the 
absolute encoder is 
lower than the 
specification.  
1. Check if the voltage of the 
battery on the panel is lower 
than 3.1 V( tentative 
specification) 
2. Check if the voltage of the 
battery is lower than 3.1 
V( tentative specification) 
Change the battery when power 
is ON which is controlled by the 
servo drive. After changing the 
battery, AL061 will be cleared 
automatically.
