Voltage pulses at the motor terminals
The pulsed output voltage of a frequency inverter rises with a steep edge. The permissible range is indicated in the figure below.
NOTICE
Risk of motor damage if voltage increase on motor terminals is too steep!
Risk of motor damage if voltage increase on motor terminals is too steep!
Observe the limits of voltage increase and voltage pulses at the motor terminals! If necessary, use sinusoidal filters.
t: rise time
U: pulse voltage on motor terminals
①: limit based on EN60034
