2009 .2 ^s, du/dt filtering not required.du/dt filters Du/dt filtering suppresses inverter output voltage spikes and rapid voltage changes that stress motor insulation. M otor type Nominal mains voltage (UN) M otor insulation requirement ABB and 500 Standard insulation system. For m ore information please see the ACS800 hardware manuals. HXR and motors du/dt filtering with voltages over 500 V. ABB form -wound 380 690 Standard insulation system. interval during which line line voltage otor term inals changes from 10% 90% of full voltage range. With du/dt filtering, the insulation system must withstand LL=1600 V. Additionally, du/dt filtering reduces capacitive leakage currents and high frequency emission the motor cable well high frequency losses and bearing currents the motor. ith du/dt filtering, the insulation system must w ithstands LL=1800 V. 600 690 Reinforced insulation system conjunction with du/dt filtering. 500 600 the insulation system withstands LL=1800 u/dt filtering not required. Symbol Explanation U Nominal mains voltage. Û Peak line line voltage otor terminals. HXR and motors ABB random -wound 380 690 heck otor insulation system with the otor manufacturer. Non-ABB 420 Insulation system must withstand LL=1300 V. For information the construction of Filter selection table for ACS800 the motor insulation, consult the manufacturer. the motor does not fulfil the following requirements, the lifetime the motor might decrease. The need for du/dt filtering depends the motor insulation. 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. 600 690 the motor insulation system withstands LL=2000 and At=0. 42 Hardware options FE68404592 REV 3.7.
