If the intermediate DC circuit voltage of the drive is increased from the nominal level due to long term resistor
braking cycles, check with the motor manufacturer if additional output filters are needed in the applied drive
operation range.

Additional data for calculating the rise time and the peak line-to-line voltage

If you need to calculate the actual peak voltage and voltage rise time considering the actual
cable length, proceed as follows:
• Peak line-to line voltage: Read the relative Û
multiply it by the nominal supply voltage (U
• Voltage rise time: Read the relative values Û
below. Multiply the values by the nominal supply voltage (U
t = 0.8 · Û /(du/dt).
