With du/dt filtering, the insulation system must withstand Ûll=1800 V. ABB form-wound 380 690 Standard insulation system. HXR and motors du/dt filtering with voltages over 500 V. With du/dt filtering, the insulation system must withstand Ull=1600 V. Additionally, du/dt filtering reduces capacitive leakage currents and high frequency emission the otor cable well high frequency losses and bearing currents the motor.2. At Rise time, i.35 times the mains network voltage with very short rise time. Non-ABB 420 Insulation system must withstand Ull=1300 V. The voltage can almost double the otor terminals, depending otor cable properties.3 ps, du/dt filtering not required. interval during which line line voltage motor terminals changes from 10% 90% full voltage range. HXR and motors ABB random-wound 380 690 Check motor insulation system with the motor manufacturer. Filter selection table for ACS800 Motor type Nominal mains Motor insulation requirement vo|tage (UJ ABB and 500 Standard insulation system. Symbol Explanation Un Nominal mains voltage. For more information see the ACS800 hardware manuals. 500 600 the insulation system withstands Ull=1800 du/dt filtering not required. W hen needed? The need for du/dt filtering depends the motor insulation. For information on the construction the motor insulation, consult the manufacturer. Random-wound and Form-wound 420 500 the insulation system withstands Ull=1600 and At=0.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. M3 motors 500 600 Standard insulation system conjunction with du/dt filtering reinforced insulation.2 ps, du/dt filtering not required. 600 690 Reinforced insulation system conjunction with du/dt filtering. 600 690 the motor insulation system withstands Ull=2000 and At=0. U Peak line line voltage motor terminals. With du/dt filtering, the insulation system must withstand Ûll=1300 V.2009 Hardware options 29 .e. Du/dt filtering suppresses inverter output voltage spikes and rapid voltage changes that stress otor insulation. 3AFE68248531 REV 20. 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. the motor does not fulfil the following requirements, the lifetime the motor might shorten
