Overcurrent power supply unit

What does F360 mean?

The DIAX04 SSE-03VRS power supply unit detected an excessive current flow. This typically indicates a short circuit or an extreme overload condition on its output (e.g., DC bus or auxiliary supplies). The unit shuts down immediately to protect its internal components and prevent further damage to connected devices.

• Short circuit on the DC bus or on one of the auxiliary voltage outputs of the DIAX04 SSE-03VRS power supply unit.
• Connected drive modules or other loads are drawing excessive current due to an internal fault.
• Internal power component failure (e.g., rectifier, inverter bridge) within the DIAX04 SSE-03VRS power supply unit.
• Sudden, high inductive load changes causing current spikes beyond the unit's rating.
• Faulty current measurement circuit within the DIAX04 SSE-03VRS power supply unit.

Click steps to track your progress.

1. 1

   Immediately disconnect all loads from the DIAX04 SSE-03VRS power supply unit (e.g., disconnect all drive modules) and attempt to power it up. If the fault clears, the issue is external.

2. 2

   Check the DC bus bar for any short circuits to ground or between phases. Inspect power cables for damage.

3. 3

   Isolate individual drive modules or auxiliary loads and reconnect them one by one to identify the faulty device.

4. 4

   Verify that the total current draw of all connected loads does not exceed the rated output current of the DIAX04 SSE-03VRS power supply unit.

5. 5

   If the fault persists with no loads connected, it indicates an internal hardware fault within the DIAX04 SSE-03VRS power supply unit, requiring factory service or replacement.
