A00525
DC-link Ripple
Siemens · SINAMICS G120 Variable Speed Drive
What does A00525 mean?
A large ripple in the DC-link voltage has been detected, which can indicate issues with the input power supply, filter capacitors, or excessive harmonic distortion. This condition can affect inverter performance, efficiency, and potentially lead to premature component failure.
Complete Troubleshooting Guide
- 1
Check the input power supply voltage for stability and ensure it is within specified limits.
- 2
Inspect DC-link capacitors for any signs of degradation, bulging, or leakage.
- 3
Verify the proper functioning of the input rectifier bridge.
