Wrong safety param. data

Hva betyr A01697 ?

A semaphore problem occurred during startup, preventing the drive from loading its last saved safety parameters and forcing it to load default values instead. This indicates a data integrity issue or timing problem, compromising the intended safety configuration and requiring immediate attention to restore safe operation.

• Corruption of non-volatile memory where safety parameters are stored, leading to invalid data loaded at startup.
• Incomplete or interrupted save operation of safety parameters, resulting in inconsistent data being written to memory.
• Drive firmware mismatch or update issue causing safety parameter structures to be misinterpreted by the control unit.
• Electromagnetic interference (EMI) during startup causing data read errors from the internal memory module.
• Hardware defect on the control board's memory unit or safety processor, leading to persistent data integrity issues.

1. 1

   1. Perform a safety parameter reset (e.g., P0970=95) and then reconfigure all safety parameters according to the machine's safety documentation.

2. 2

   2. Reload the safety parameters from a known good backup file using the engineering software (e.g., STARTER) and then acknowledge the changes (P0976).

3. 3

   3. Update the drive's firmware to the latest stable version to address any potential software bugs related to parameter storage.

4. 4

   4. Verify the integrity of the power supply to the drive, checking for voltage sags or interruptions during startup sequences.

5. 5

   5. If the issue persists after reconfiguring and reloading, consider replacing the main control board as a memory hardware fault may be present.
