Delta AL809 fault code meaning
Delta / AL809
Series: ASDA-A3, ASDA-H3
PR basic numerical calculation or secondary platform execution error
servo drive
Meaning: A command interpretation error occurs when the drive executes a motion command.
Possible causes
- Condition: A command interpretation error occurred while the drive was executing a motion command. Cause: PR arithmetic operations must be compiled using ASDA-Soft before they can be downloaded to the drive. If the PR arithmetic operation parameters are written or modified directly through the panel or host controller without compilation using ASDA-Soft software, AL809 occurs.
