Output filters Factory installed filters. 500 600 Standard insulation system conjunction with du/dt filtering reinforced insulation. Du/dt filtering suppresses inverter output voltage spikes and rapid voltage changes that stress motor insulation. 3AFE 68248531 REV 31. 420 500 the insulation system ithstands ÛLL=1600 and At=0.2004 25 . ABB form ound HXR and otors 380 690 Standard insulation system. W ith /dt filtering, the insulation system must ithstand ÛLL=1600 V.3 ^s, du /dt filtering not required. N on-ABB R andom ound Un 420 Insulation system must ithstand ÛLL=1300 V. As with all frequency converters employing the most modern IGBT inverter technology, the ACS800 output comprises regardless output frequency pulses of approximately 1.2 ^s, du/dt filtering is not required.3.35 times the mains network voltage with very short rise time. . 600 690 the otor insulation system ithstands ÛLL=1800 du/dt filtering not required. The voltage can almost double the motor terminals, depending motor cable properties. Additionally, du/dt filtering reduces capaci­ tive leakage currents and high frequency emission of the motor cable well high frequency losses and bearing currents the motor. du /dt filtering with voltages over 500 V. Insulated N-end (non-driven end) bearings and or common mode filters are also required for motor bearing currents with motors bigger than 100 kW. A Rise tim i. For more information see the ACS800 hardware manuals. With du/dt filtering, the insulation system must withstand ÛLL=1300 V.e. 500 600 the insulation system ithstands ÛLL=1800 /dt filtering not required. the motor does not fulfil the following requirements, the lifetime the motor might shorten.
