Contents of this chapter
This chapter describes how to select d u /d t and sine filters for the drive.
du/dt filters
￭ When is a du/dt filter necessary?
See Examining the compatibility of the motor and drive (page 62) .
Note for drive modules with motor cable length less than 20 m (65 ft) from each drive
module before connecting them together
: In addition to the requirements given in
Examining the compatibility of the motor and drive (page 62) , ABB requires d u /d t filters or
sine filters at the outputs of the drive modules for equalization of drive module currents. See
also section
Motor connection data (page 150) for the minimum motor cable length. If there
is no d u /d t filter and the motor cable length from each drive module is less than 20 m (65 ft),
the nominal values of the drive must be de-rated by 15%.
