Troubleshooting

AL809 PR arithmetic operation error or second development platform error

Condition: an error occurs when the servo drive decodes the motion command.

Trigger condition

and cause

Cause: the PR arithmetic operation must be compiled by the ASDA-Soft software

before being downloaded to the servo drive. Editing or modifying the PR arithmetic

operation parameters through the panel or controller without compiling them by

ASDA-Soft triggers AL809.

1. Make sure you edit the PR arithmetic operation parameters through ASDA-Soft.

Do not modify these parameters through the panel or controller.

Checking method 2. If this alarm occurs when the servo is not in the PR mode, save the parameter

and corrective

action

file and provide it to the distributor.

3. For advanced users: save the scope screenshot when the alarm occurs.

Set P5.007 and P0.001 for the two channels and save the oscillogram.

How to clear the

alarm?

Cycle power on the servo drive.
