Danfoss VLT AQUA Drive FC 202 Design Manual

These values are true to steady state operation and at RMS input voltage range of the drive V
line
. When the drive operates in
braking mode, the intermediate DC-link voltage increases by 20%. This eect is similar to increasing the mains voltage by
20%. Consider this voltage increase when performing motor insulation analysis for braking applications.
