Error power supply E-Stop

What does F273 mean?

The DIAX04 SSE-03VRS drive's power supply for the Emergency-Stop (E-Stop) circuit has an error. This signifies that the voltage supply for the E-Stop monitoring is faulty or an overload/short circuit is detected. This is a critical safety fault, as the E-Stop function cannot be guaranteed, requiring immediate shutdown to ensure personnel and machine safety.

• Short circuit or overload on the E-Stop circuit power supply output.
• Damage to the wiring connected to the DIAX04 SSE-03VRS E-Stop input circuit.
• Faulty E-Stop button or external safety relay drawing excessive current or internally shorted.
• Internal fault within the DIAX04 SSE-03VRS drive's power supply circuit for safety inputs.
• Loss of 24VDC control voltage feeding the DIAX04 SSE-03VRS safety input section.

Click steps to track your progress.

1. 1

   Disconnect all E-Stop related wiring from the DIAX04 SSE-03VRS drive's safety input. If the fault clears, the issue is external.

2. 2

   Measure the voltage at the E-Stop circuit power supply output terminals on the DIAX04 SSE-03VRS. Verify it's within specification (e.g., 24VDC).

3. 3

   Check the E-Stop wiring for shorts to ground or power, and for continuity. Inspect E-Stop buttons and safety relays for proper function.

4. 4

   Isolate external safety components one by one to identify the faulty device or wiring section.

5. 5

   If the fault persists even with external wiring disconnected, there may be an internal fault with the DIAX04 SSE-03VRS drive's safety input power supply circuit.
