Fundamental Principles and System Description
Engineering Information
Note:
All data in this section are applicable on the condition that the motor cables are connected directly to the inverter
output and no motor reactors, dv/dt filters plus VPL, dv/dt filters compact plus VPL or sine-wave filters are used.
Using dv/dt filters plus VPL, dv/dt filters compact plus VPL or sine-wave filters makes a critical difference to the
voltage rates-of-rise and voltage spikes on the motor and alters the conditions to such an extent that motors with
special insulation are not required. The use of these filters does however impose certain limitations and these are
described in detail in sections "dv/dt filters plus VPL and dv/dt filters compact plus VPL" and "Sine-wave filters".
