Test stop for fail-safe digital output running

Hva betyr A30772 ?

A forced checking procedure (test stop) for the fail-safe digital output is currently in progress. This is a normal safety test to verify the output's functionality and indicates that the system is performing a self-check.

• Automatic periodic test initiated by the safety control system for fail-safe digital outputs to ensure functionality.
• Manual activation of an F-DO test via safety PLC or HMI during commissioning or maintenance.
• Commissioning or re-validation procedure requiring F-DO testing after a configuration change.
• Internal self-test sequence of the safety module requiring a temporary test of its F-DOs.

1. 1

   Monitor the status LED of the fail-safe digital output module (e.g., integrated safety board) to observe test activity.

2. 2

   Access the drive's diagnostic interface to monitor the F-DO status word (r0947.x) for test progress and completion.

3. 3

   Wait for the F-DO test sequence to complete, which typically lasts only a few milliseconds.

4. 4

   Verify that the connected external safety device (e.g., safety contactor K1) responds correctly to the test pulses after the test.

5. 5

   Confirm the system returns to normal operation after the test without triggering any F-codes.
