| Space Vector Modulation Improves Efficiency By controlling the IGBT power devices using Space Vector Modulation (SVM) instead of the more usual carrier based pulse width modulation (PWM), users can run seivo motors at higher speeds without introducing harmonics. In today's world of increased productivity, this can translate directly into greater machine throughput. SVM is supported by MicroFlex, MicroFlex e100, EuroFlex and H2. Digital Filters Eliminate Resonance Advanced digital filtering techniques can be applied to reduce the effect of mechanical resonance on system performance. The drive has two separate digital filters. Each can be adapted to specific frequencies as notch filters, or as low pass filters. Adapting the filters to eliminate or reduce the effects of resonance allow higher system gains and tighter control to be attained. This maximizes machine control bandwidth, without suffering from the increased resonance and performance degradation that would otherwise result. Configuring these filters is aided by a simple filter design interface which, combined with the Mint WorkBench oscilloscope and FFT (Fast Fourier Transform) analysis, allows the user to test the axis open and closed loop frequency response. The resonant components can then be identified and filter designs tested for effectiveness. Digital filters are supported by MicroFlex, MicroFlex e100, EuroFlex and H2. |
