Illustration 8.10 Star and Delta Connections
All types of 3-phase asynchronous standard motors can be
connected to the frequency converter. Normally, small
motors are star-connected (230/400 V, Y). Large motors are
normally delta-connected (400/690 V,
Δ
). Refer to the
motor nameplate for correct connection mode and
voltage.
