These motor drive analyzers simplify troubleshooting on single-phase and three-phase motor-drive systems by providing guided testing that enables technicians to quickly capture the most important measurements, eliminating the hassle of setting up complex measurements, simplifying the troubleshooting process and delivering reliable, repeatable test results. Technicians simply select a test and the step-by-step guided instructions show precisely where to make voltage and current connections, while the preset measurement profile ensures that all the necessary data is captured for each motor-drive section — from the input to the output, the DC bus, and the motor itself. The units measure key motor-drive parameters including voltage, current, DC bus voltage level and AC ripple, voltage and current unbalance and harmonics (MDA-550 only), voltage modulation, and motor shaft voltage discharges (MDA-550 only); they perform extended harmonics measurements to identify the effects of low and high order harmonics on electrical power systems and measure additional electrical parameters with full 500 MHz oscilloscope, meter, and recording capability for complete range of electrical and electronic measurement on industrial systems. The units create as-found and as-left reports quickly and easily by pressing “save to report” at any test point or measurement.
