Hva betyr F384 ?

With HVR power supply units only! This fault indicates that the power and control voltage connections are not in phase, specifically that terminals X5/U and X8/1, X5/V and X8/2, X5/W and X8/3 are conducting voltage to each other.

• Power and control voltage connections are incorrectly wired or in phase with each other.

1. 1

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

2. 2

   Verify the wiring between the power input terminals (X5/U, X5/V, X5/W) and the control voltage input terminals (X8/1, X8/2, X8/3) for incorrect connections or cross-wiring.

3. 3

   Using a multimeter in continuity or resistance mode, check for unintended electrical connections or short circuits between X5/U and X8/1, X5/V and X8/2, and X5/W and X8/3. There should be no continuity.

4. 4

   Correct any incorrect wiring or short circuits identified between these terminal groups.
