As with all frequency converters employing the most modern IGBT inverter technology, the ACS800 output comprises regardless output frequency pulses of approximately 1.

For more information see the ACS800 hardware manuals. 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. For information the construction the motor insulation, consult the manufacturer.3 ^s, du /dt filtering not required. 600 690 the otor insulation system ithstands ÛLL=1800 du/dt filtering not required.e. Non-ABB Form -wound 600 690 the otor insulation system ithstands ÛLL=2000 and At=0. Du/dt filtering suppresses inverter output voltage spikes and rapid voltage changes that stress motor insulation. the motor does not fulfil the following requirements, the lifetime the motor might shorten. 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. The voltage can almost double the motor terminals, depending motor cable properties.
