ACH550-UH User’s Manual 1-309Technical dataMotor connectionsWARNING! Never connect line power to the drive output terminals: U2, V2 or W2.Line voltage applied to the output can result in permanent damage to the unit. Iffrequent bypassing is required, use mechanically interlocked switches or contactors.WARNING! Do not connect any motor with a nominal voltage less than one half ofthe drive’s nominal input voltage.WARNING! Disconnect the drive before conducting any voltage tolerance (Hi-Pot)test or insulation resistance (Megger) test on the motor or motor cables. Do notconduct these tests on the drive.Motor connection specificationsMotor Connection SpecificationsVoltage (U2 ) 0…U1 , 3-phase symmetrical, U max at the field weakening pointFrequency 0…500 HzFrequency Resolution 0.01 HzCurrent See Ratings on page 1-297.Field Weakening Point 10…500 HzSwitching FrequencySelectable: 1, 4, 8, or 12 kHz(1, 4, or 8 kHz for 600 V, R6 frame size, that is forACH550-xx-077A-6 … ACH550-xx-144A-6)Minimum CableTemperature Rating60 °C (140 °F) for field wiring terminals for circuits of 100 A or less.75 °C (167 °F) for field wiring terminals for circuits over 100 A.Maximum Motor CableLengthFrame Size Max.
