Charging Fault

What does 4 mean?

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.

• 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.

1. 1

   Inspect the external charging circuit components, including the charging resistor, for proper dimensioning and integrity.

2. 2

   Verify the value of parameter P.2.1.3 (MaxChargeTime) to ensure it is adequately set for the system.
