U Peak line line voltage motor terminals. With du/dt filtering, the insulation system must withstand Ull=1600 V. Du/dt filtering suppresses inverter output voltage spikes and rapid voltage changes that stress otor insulation. 600 690 the motor insulation system withstands Ull=2000 and At=0. interval during which line line voltage motor terminals changes from 10% 90% full voltage range. For more information see the ACS800 hardware manuals.3 ps, du/dt filtering not required. Insulated N-end (non-driven end) bearings and or com ode filters are also required for motor bearing currents with motors bigger than 100 kW. ABB form-wound 380 690 Standard insulation system. 600 690 Reinforced insulation system conjunction with du/dt filtering. M3 motors 500 600 Standard insulation system conjunction with du/dt filtering reinforced insulation.Du/dt filters As with all frequency converters employing the most m odern inverter technology, the ACS800 output comprises regardless output frequency pulses of approximately 1.2009 Hardware options 29 . HXR and motors du/dt filtering with voltages over 500 V. Symbol Explanation Un Nominal mains voltage. HXR and motors ABB random-wound 380 690 Check motor insulation system with the motor manufacturer. Random-wound and Form-wound 420 500 the insulation system withstands Ull=1600 and At=0.2 ps, du/dt filtering not required. With du/dt filtering, the insulation system must withstand Ûll=1800 V. 3AFE68248531 REV 20. For information on the construction the motor insulation, consult the manufacturer. 500 600 the insulation system withstands Ull=1800 du/dt filtering not required.2.35 times the mains network voltage with very short rise time.e. the motor does not fulfil the following requirements, the lifetime the motor might shorten. At Rise time, i. Additionally, du/dt filtering reduces capacitive leakage currents and high frequency emission the otor cable well high frequency losses and bearing currents the motor. With du/dt filtering, the insulation system must withstand Ûll=1300 V. Non-ABB 420 Insulation system must withstand Ull=1300 V. Filter selection table for ACS800 Motor type Nominal mains Motor insulation requirement vo|tage (UJ ABB and 500 Standard insulation system. The voltage can almost double the otor terminals, depending otor cable properties. W hen needed? The need for du/dt filtering depends the motor insulation
