ASDA-A2
AL042：Analog input voltage error
Causes
The analog input voltage
is higher than the value of
P1-83.
AL044：Warning of servo drive function overload
Causes
Warning of servo drive
function overload
AL045： Wrong setting of E-gear ratio
Causes
Setting of E-gear ratio is
wrong when power on the
servo drive
AL060：The absolute position is lost
Causes
Battery undervoltage
Change the battery when
the power is OFF which
is controlled by the servo
drive
After activating the
absolute function, the
absolute coordinate
initialization has not been
completed.
Bad connection of the
battery power circuit
10-18
Checking Method
Check if analog input voltage is too
high.
Checking Method
N/A
Checking Method
Check if the setting of E-gear ratio
is within the range (1/50~25600).
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.
Chapter 10 Troubleshooting
Corrective Actions
Check all analog input voltages.
Check if there is any problem about
the sources of analog speed
commands.
Corrective Actions
Set P2-66 Bit4 to 1 can disable the
display of this alarm.
Corrective Actions
Modify the range of E-gear ratio
and repower on the servo drive.
Corrective Actions
After change the battery, conduct
homing procedure again. Please
refer to the description of absolute
coordinate initialization in Chapter
12.
Conduct homing procedure again.
Please refer to the description of
absolute coordinate initialization in
Chapter 12.
Conduct homing procedure. Please
refer to the description of absolute
coordinate initialization 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 absolute coordinate
initialization in Chapter 12.
