HXR and motors ABB random -wound 380 690 heck otor insulation system with the otor manufacturer. 600 690 the motor insulation system withstands LL=2000 and At=0. the motor does not fulfil the following requirements, the lifetime the motor might decrease. Random -wound and Form -wound 420 500 the insulation system withstands LL=1600 and At=0. Û Peak line line voltage otor terminals.e. ABB form -wound 380 690 Standard insulation system.7. ith du/dt filtering, the insulation system must w ithstands LL=1800 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. The need for du/dt filtering depends the motor insulation. For m ore information please see the ACS800 hardware manuals.du/dt filters Du/dt filtering suppresses inverter output voltage spikes and rapid voltage changes that stress motor insulation. With du/dt filtering, the insulation system must withstand LL=1600 V. ith du/dt filtering, the insulation system must withstand LL=1300 V. M otor type Nominal mains voltage (UN) M otor insulation requirement ABB and 500 Standard insulation system. For information the construction of Filter selection table for ACS800 the motor insulation, consult the manufacturer.
