ASDA-A2
AL067：Encoder temperature warning
Causes
Encoder temperature
exceeds the warning
level. (But it is still within
the protective range 85°C
to 100°C, 185°F to
212°F.)
AL068：Absolute data transmitted via I/O is in error
Causes
Sequence error
Reading time out
AL069：Wrong motor type
Causes
Incremental motor is not
allowed to activate the
absolute function.
AL06A：The absolute coordinate has not been initialized
Causes
Voltage of the battery is
normal, but the encoder
loses number of
revolutions.
1. The motor is used for
the first time.
2. The battery had run
dry but has replaced a
new one.
3. Poor connection or
disconnection of the
battery power circuit.
10-22
Checking Method
Check the setting: Set the value of
P0-02 to 120 to display the
temperature.
Checking Method
1. Switch OFF DI ABSQ until DO
ABSR is OFF.
2. Switch ON ABSQ until DO
ABSR is ON.
Check if the time between
switching ON DO ABSR and
switching ON ABSQ exceeds
200 ms.
Checking Method
1. Check if the motor is
incremental or absolute
encoder.
2. Check parameter P2-69.
Checking Method
1. Check if the absolute origin
coordinate has been created.
2. Check the encoder wiring.
3. Check the connection between
the battery box and the servo
drive.
Chapter 10 Troubleshooting
Corrective Actions
1. Improve heat dissipation or
reduce the loading of operation.
The temperature should be
lower than 100°C (212°F).
2. If the encoder's temperature is
higher than the motor's (more
°C (86°F)
than 30
send the motor back to the
distributors.
Corrective Actions
Correct the reading sequence of
I/O.
After switching ON DO ABSR (the
absolute position data is ready),
read DO ABSD and switch ON DI
ABSQ within 200 ms so as to
inform the servo drive data reading
is completed.
Corrective Actions
If the user desires to use the
absolute function, please choose an
absolute motor. If not, please set
parameter P2-69 to 0.
Corrective Actions
1. Create the absolute origin
coordinate.
2. Ensure the battery wiring and
execute homing again.
