Activation of a safety function wrong

What does F505 mean?

The DIAX04 SSE-03VRS drive detected an error during the activation or deactivation of an integrated safety function. This means the safety state transition did not occur as expected, potentially due to incorrect input signals, parameter mismatch, or an internal fault. The drive faults to prevent an unsafe or undefined state.

• Safety input signals for the commanded safety function (e.g., STO, SS1, SLS) are incorrect or inconsistent.
• Parameters for the safety function are improperly configured or conflict with other settings in the DIAX04 SSE-03VRS drive.
• Internal fault within the DIAX04 SSE-03VRS drive's safety module preventing proper activation/deactivation.
• External safety relay or safety PLC communicating incorrect status to the DIAX04 SSE-03VRS.
• Wiring issues on the safety input channels to the drive.

Click steps to track your progress.

1. 1

   Verify the status of all safety input signals connected to the DIAX04 SSE-03VRS drive. Ensure they are correct for the intended safety function activation.

2. 2

   Check the configuration of all active safety functions and their associated parameters in the DIAX04 SSE-03VRS drive for consistency and correctness.

3. 3

   Inspect all wiring for safety-related inputs for damage, loose connections, or incorrect termination.

4. 4

   If using an external safety PLC or relay, verify its output signals to the DIAX04 SSE-03VRS are correct and synchronized.

5. 5

   Perform a full power cycle of the DIAX04 SSE-03VRS system. If the fault persists, consider a fault with the drive's internal safety module.
