All types of three-phase asynchronous stand-ard motors can be connected to the adjustablefrequency drive. Normally, small motors arestar-connected (230/400 V, D/Y). Large mo-tors are delta-connected (400/690 V, D/Y).Refer to the motor name plate for the correctconnection mode and voltage.Illustration 4.10: Terminals for motor connectionNOTEIn motors without phase insulation paper or other insulation reinforcement suitablefor operation with a voltage supply (such as an adjustable frequency drive), fit asine-wave filter on the output of the adjustable frequency drive. (Motors that complywith IEC 60034-17 do not require a sine-wave filter).No. 96 97 98 Motor voltage 0-100% of line voltage.U V W 3 cables out of motorU1 V1 W1 6 cables out of motor, Delta-connectedW2 U2 V2U1 V1 W1 6 cables out of motor, Star-connectedU2, V2, W2 to be interconnected separately(optional terminal block)No. 99 Ground connectionPETable 4.6: 3 and 6 cable motor connection.4.1.10.
