Figure 8.10 Star and Delta Connections
All types of three-phase asynchronous standard motors can
be connected to the adjustable frequency drive. 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.
