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.
A
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.
A
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.
