AL2A ABS encoder abnormal 1
Cause
Inspection
Remedy
The voltage of encoder battery is
low.
1. Check the voltage of encoder
battery whether is less than 2.45
volt.
After replacing battery, execute the
origin return.
The bad contact between encoder
and battery, or the battery power
lines disconnected.
1. Check the encoder wirings.
2. Check the contacts between the
encoder power lines and battery
box.
After the wirings repairing, execute
the origin return.
AL2B ABS encoder abnormal 2
Cause
Inspection
Remedy
The counter of encoder revolutions
is abnormal.
Power off the servo drive, and then
run the servo motor, check whether
it is a recurrence.
If there is still a recurrence, please
contact your agent for service.
AL2C ABS encoder abnormal 3
Cause
Inspection
Remedy
Replace the encoder batter when
the power of servo drive has turned
off.
Not to replace the encoder battery
unless the power of servo drive is
on.
Execute the origin return.
The absolute coordinate
initialization has not executed when
the absolute coordinate system
operated.
---
Execute the origin return.
AL2D Encoder battery voltage low
Cause

Remedy
The voltage of encoder battery is
low.
1. Check the LED display whether
AL2D message is shown.
2. Measure the battery voltage.
Please keep the power of servo
drive and then replace the battery
of encoder.
