11.7.1. Reason for and handling of the alarm
AL030 : Encoder over voltage or internal error
Reason for abnormality
Check for abnormality
Handling for abnormality
Battery over voltage
1. Check battery. (voltage> 3.8V)
Replacing the battery.
Encoder internal error
1. Check encoder type, absolute or
incremental.
2. Check if the motor connected to
ground.
3. Check if the encoder cable is
too close to power cable.
4. Check if the mesh is used for the
filament of the encoder.
1.If the situation is not improved,
return the drive the factory for repair
2. Connect the power cable
ground(green) with driver.
3. Separate the power and encoder
cable.
4. Use the filament with mesh.
AL033 : Absolute position lose
Reason for
abnormality
Check for abnormality
Handling for abnormality
Battery low voltage
Check if battery voltage
lower than 1.2V.
Replace the battery and re-
initialize system.
Refer to 11.3.4~11.3.5.
Absolute system is
not initialized.
1. Install battery.
2. Check battery and
cable.
Replace the battery and re-
initialize system.
Refer to 11.3.4~11.3.5.
