Vacon · NX Liquid-Cooled Drive
Was bedeutet 4 ?
The pre-set charging time for the DC-link, defined by parameter P.2.1.3 (MaxChargeTime, default 5 seconds), has been exceeded. Specifically, the DC voltage failed to rise above 40VDC within 1 second during the initial charging sequence.
Häufige Ursachen
- DC bus voltage not reaching nominal levels during charging.
- Faulty charging contactor or relay.
- Internal failure in the power supply unit.
- Issue with rectifier bridge or input power.
