Parameter processor 2 incorrect

What does F01656 mean?

Parameter processor 2 is reporting an incorrect state or value, which could affect safety function processing. This can prevent proper configuration and operation of safety features, potentially leading to an unsafe state or system malfunction.

• Internal hardware defect within the Control Unit's second safety processor (F-CPU).
• Firmware corruption or an error during the boot-up sequence of the safety processor.
• Severe electromagnetic interference (EMI) causing transient errors in the processor's operation.
• Overheating of the Control Unit leading to unreliable processor operation.
• Incompatible firmware versions between different safety-related components (e.g., Control Unit and a safety expansion module).

Click steps to track your progress.

1. 1

   Perform a full power cycle of the drive system to reset the Control Unit's processors.

2. 2

   Check the ambient temperature around the drive and ensure proper cooling airflow to the Control Unit.

3. 3

   Verify the firmware version of the Control Unit is the latest recommended version and compatible with the application.

4. 4

   Execute a factory reset of the safety parameters (e.g., via P9700=0) and then re-commission the safety functions.

5. 5

   Monitor the drive's internal diagnostic logs for other processor-related errors or temperature warnings.
