Drive Commissioning FAQs
What is the difference between V/f control and closed-loop vector control for VFDs?
V/f control maintains a constant voltage-to-frequency ratio suitable for basic pumps and fans. Closed-loop vector control utilizes encoder feedback to independently regulate motor flux and torque, providing high starting torque and precise speed regulation at near-zero speeds.
How do you resolve mechanical resonance issues during servo tuning?
We perform frequency sweep analysis to identify mechanical resonance peaks, then apply programmable notch filters and low-pass filters within the servo drive firmware to suppress vibration without sacrificing bandwidth.
