Mains chokes
Contents of this chapter
This chapter describes how to select and install mains chokes for the drive module.
The chapter also contains the relevant technical data.
When is a mains choke required?
With frames R1 and R2, the need for an external choke should be determined on a
case-by-case basis. With frames R3 and R4, the drive modules have an internal
mains choke.
The main choke typically
• reduces harmonics in the input current
• reduces the r.m.s. input current
• reduces supply disturbance and low-frequency interference
• increases the allowed DC bus continuous power
• ensures even current distribution in common DC configurations (see
