This alarm indicates that the cyclic transfer of the PUTFTOCF data block (fine tool compensation) failed because the transfer area is already occupied. This commonly occurs if another channel is simultaneously attempting to transfer a data block, creating a resource conflict. If left unaddressed, this prevents fine tool compensation from being applied, potentially leading to inaccuracies in machining and affecting product quality.
Click steps to track your progress.
1. Review the PLC program and HMI scripts to ensure only one source is attempting to write to the fine tool compensation data block at any given time.
2. Introduce a delay or handshake mechanism in the PLC program to ensure the previous data transfer is complete before initiating a new PUTFTOCF command.
3. Check the drive's internal diagnostic parameters (e.g., r2000, r2001 for communication status) to identify any active data transfer locks.
4. Verify the integrity and format of the data block (e.g., correct data types, length) being sent with the PUTFTOCF command.
5. Cycle power to the drive to clear any temporary memory lock-ups or buffer issues.
