Issue: Causes of an USF fault on ATV61 drives. Product line: ATV61, ATV71, Altivar 61, Altuvar 71 Environment: All models Cause: Undervoltage supply. Resolution: The USF fault occurs when the DC bus voltage level drops below the threshold set in 1.8 Fault Management > Undervoltage Management > Undervoltage level. For N4, 480V drives at factory setting of 480VAC, the threshold is 430VDC on the DC bus or 304VAC on the line terminals. For M3, 240V drives at factory setting of 260VAC, the threshold is 230VDC on the DC bus or 163VAC on the line terminals. For Y, 575V drives at factory setting of 690VAC, the threshold is 571VAC on the DC bus, or 404VAC on the line terminals. Recommendations: - Measure the the incoming line to line voltages - Compare the line voltage to the Mains Voltage as shown under Menu 1.2 Monitoring, and also the measurement of the DC bus voltage. - If the standard line voltage is low, you can adjust the Mains voltage setting. - Adjust the Undervoltage time out to compensate for line contactors, or add time delay before a fault would occur.

Issue: USF (undervoltage fault) on an ATV12 drive. Product Line: Altivar 12 Environment: All Cause: Fault condition Resolution: For N4, 480V drives at factory setting of 480VAC, the threshold is 430VDC on the DC bus or 304VAC on the line terminals. For M3, 240V drives at factory setting of 260VAC, the threshold is 230VDC on the DC bus or 163VAC on the line terminals. Recommendations: - Measure the the incoming line to line voltages - Compare the line voltage to the Mains Voltage as shown under monitoring MON. - If the standard line voltage is low, you can adjust the Mains voltage setting - Adjust the Undervoltage time out to compensate for line contactors, or add time delay before a fault would occur. - Check to issues where line potential is dropping due to supply issues that may be caused by load pulling too much current.

No, when using a 3rd party motor with Lexium32M it is the user's responsibility to operate the Lexium 32 drive from a mains voltage within the range of the 3rd party motor being used. For example, if a 3rd party motor connected to the Lexium32 drive has a ,maximum voltage rating of 300vac then the mains voltage applied to the Lexium32 should not be higher then 300vac. By comparison, if the Lexium32 drive was connected to 480vac this would exceed the motor manufacturers design specifications for insulation within the winding, connectors, terminal....ect. and would not be recommended and could result in motor failure and or a hazardous situation due to insulation rating of the motor. rev 7.19.17

Issue USF showing on the ATV312 drives. Product Line: Altivar ATV31 and ATV312 Environment: All Cause: Drive is tripping on USF or undervoltage fault. Resolution: USF means undervoltage fault. Get a digital meter and check your input line voltages on L1 L2 L3 ATV312........M2 drive will trip on USF if the line voltage is 160VAC or less ATV312........M3 drive will trip on USF if the line voltage is 160VAC or less ATV312........N4 drive will trip on USF if the line voltage is 300VAC or less ATV312........S6 drive will trip on USF if the line voltage is 430VAC or less
