TM 5-3895-374-24-1Recommendations for useof the motor/speed controller combinationOperation at constantThis type of operation is possible providing the motor winding torque is adjusted, and thetorque in overspeedvoltage / frequency ratio adapted The various possibilities are specified belowExample : ATV-452--- (380/415 V)motor 240 ( A)/415 V (A)Motor connected in k (coupling 1)Motor connected at A (coupling 2)Operation at constant torqueOperation at constant torqueup to 50 (60) Hzup to 87 (104) HzEnsure that the motor is suitable for overspeed operationIn the event of operation with low voltage connection (connection 2), the rated current to beused for speed controller selection is that taken by the motor when connected in thisconfigurationExample operation of a 4 kW 1500 rpm 415 V 50 Hz motor at 87 Hz, the power at 2610rpm is 7 kW Rated current at 240 V 16,5 A Speed controller selected ATV-452U75 (7,5 kW - 17,5 A)Various types of motor to be usedcoupling 2 / coupling 1ATV-452===M(220/240 V)127 V (D)/ 220 V ()139 V (D)/ 240 V ()ATV-452===.(380/415 V)220 V (D)/ 380 V ()240 V (D)/415 V ()ATV-452===N(440/500 V)250 V (D)/ 440 V ()290 V (D)/ 500 V ()230 V (L)/ 460 V ( H)ATV-452===S(525/575 V)300 V (D) / 525 V ()330 V(D)/575 V (A)Installation of the motor Mount and couple the motor carefully, so as to eliminate any possible problems withvibrations and resonance(page 3-185)
