Issue:
What is the purpose of using output filter with an AC drive?
Product Line:
Altivar drives
Environment:
All
Cause:
N/A
Resolution:
Output filters protect the motor in against The Reflective Wave Phenomenon and dV/dT Peak Voltages due to long motor lead length or high cable capacitance.
Additionally, the added inductance of a filter may help reduce motor heating, motor noise, and motor vibration.
