Operation Data 12.1 Frequency Response Characteristics Inverter ; FRN37VG7S-4 Motor ; MVK6207A-C, 37kW, 1500/3600r/min Test condition ; Motor only 12.2 Sample Measurement of Motor Wow Inverter ; FRN37VG7S-4 Motor ; MVK6207A-C, 37kW, 1500/3600r/min Test condition ; Motor only 12-1 • Because of the improvement of the frequency response, 1) The motor wow was reduced to approximately 60% of the conventional one. 2) Follow-up characteristics at the time of load fluctuation improved. 3) Position synchronizing accuracy improved. 4) Step response characteristics of speed improved.
12.3 Current Response Characteristics • By realizing the current response of 800Hz, the waveform distortion of output current was reduced. • The harmonic of 5,7,11,13 times caused from PWM control was reduced. This leads to the reduction of torque ripple. 12.4 Torque Ripple VG7S VG5 Inverter ; FRN37VG7S-4 Motor ; MVK6207A-C, 37kW, 1500/3600r/min Test condition ; 100% load Torque ripple P−P 100%:Rated torque 1 time 2 times 4 times 6 times VG7S 0.23% 0.22% 0.10% 1.49% VG5 0.70% 0.20% 0.09% 1.60% Inverter ; FRN37VG7S-4 Motor ; MVK6207A-C, 37kW, 1500/3600r/min Test condition ; Motor constraint 12-2
