ASDA-A2 Chapter 12 Absolute System
12-34 Revision February, 2017
Causes Checking Method Corrective Actions
of absolute coordinate
initialization in Chapter 12.
AL062: Encoder under voltage
Causes Checking Method Corrective Actions
Battery under voltage
1. Check if the voltage of the battery on
the panel is lower than 3.1 V (tentative
specification).
2. Measure if the voltage of the battery is
lower than 3.1 V (tentative
specification).
Do not change the battery when
the power is ON which is
controlled by the servo drive.
After change the battery, AL061
will be cleared automatically.
AL062: The multi-turn of absolute encoder overflows
Potential Cause Checking Method Corrective Actions
The operation
distance exceeds the
range the absolute
encoder is able to
record
Check if the operation distance exceeds
the range, -32768 ~ +32767, the absolute
encoder is able to record.
Conduct homing procedure
again. Please refer to the
description of absolute
coordinate initialization in
Chapter 12.
AL068: Absolute data transmitted via I/O is in error
Causes Checking Method Corrective Actions
Sequence error
1. Switch OFF DI ABSQ should wait until
DO ABSR is OFF.
2. Switch ON ABSQ should wait until DO
ABSR is ON.
Correct the reading sequence of
I/O
Reading time out
Check if the time between switching ON
DO ABSR and switching ON ABSQ
exceeds 200ms.
After switching ON DO ABSR
(the absolute position data is
ready), read DO ABSD and
switch ON DI ABSQ within
200ms so that to inform the
servo drive data reading is
completed.
AL069: Wong motor type
Causes Checking Method Corrective Actions
Incremental motor is
not allowed to
activate the absolute
function
1. Check if the motor is incremental or
absolute encoder.
2. Check parameter P2-69.
If the user desires to use
absolute function, please
choose absolute motor. If not,
please set parameter P2-69 to
0.
AL289: Feedback position counter overflows
Causes Checking Method Corrective Actions
Feedback position
counter overflows
This alarm will not occur at the moment. If
it does, please contact the distributors.
