Safe disable

What does 30 mean?

The 'Safe Disable' input on an OPTAF board has opened, activating a safety interlock that prevents drive operation. This feature is typically used to safely shut down or inhibit the start-up of the drive for maintenance or emergency situations. The drive will remain disabled until this safety condition is cleared.

• Activation of an external safety device (e.g., emergency stop button, safety light curtain, door interlock) connected to the OPTAF board's Safe Disable inputs (e.g., SD1, SD2).
• Break in the wiring to the Safe Disable inputs (e.g., SD1, SD2) on the OPTAF board, causing an open circuit.
• Internal fault or malfunction within the OPTAF board's safety monitoring circuit.
• Incorrect parameter configuration related to Safe Disable inputs (e.g., P6-01 "STO function") or acknowledgment sequence.

Click steps to track your progress.

1. 1

   Verify the status of all external safety devices connected to the OPTAF board's Safe Disable inputs (e.g., SD1, SD2) and ensure they are in a safe (closed circuit) state.

2. 2

   Measure voltage and continuity at the Safe Disable input terminals (e.g., SD1, SD2) on the OPTAF board to confirm the external circuit is properly closed.

3. 3

   Inspect the wiring from external safety devices to the OPTAF board for breaks, loose connections, or short circuits.

4. 4

   Attempt to acknowledge or reset the safety fault via the drive's control panel or software if an acknowledgment function is available (e.g., pressing "Reset" button).

5. 5

   Review relevant safety parameters (e.g., P6-01 "STO function," P6-02 "STO acknowledgment") to ensure correct configuration for the safety system.
