1) 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
The diagrams below show the relative peak line-to-line voltage and rate of change of voltage
as a function of the motor cable length. 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

multiply it by the nominal supply voltage (
