Overcurrent power supply unit

What does F360 mean?

With HVR power supply units only! This fault indicates an overcurrent condition within the Indramat HVR power supply unit, potentially caused by a short circuit in the power supply unit itself, a connected drive controller, the motor, or the motor cable.

• Short-circuit within the HVR power supply unit.
• Short-circuit in a connected drive controller.
• Short-circuit in the motor or motor cable.

Click steps to track your progress.

1. 1

   De-energize the Indramat HVR power supply unit and ensure all power is locked out.

2. 2

   Systematically disconnect the power supply lines to individual Indramat DIAX04 SSE-03VRS drive controllers connected to the HVR unit, one at a time.

3. 3

   Check the power cables and motor windings for each drive controller and motor for short circuits or ground faults using a multimeter or insulation tester.

4. 4

   Re-energize the HVR unit, reconnecting drive controllers one by one, to isolate the specific component causing the overcurrent fault.

5. 5

   If the fault persists with all loads disconnected, the short circuit is likely internal to the HVR power supply unit, requiring its replacement.
