ABB ACS400 drive giving FL4 fault indication without load connected without motor connected to the output ?
Generating DC Bus Voltage ...... as the frequency starts to increase from 0 till 4 Hz the fault appears ........
FL04 means " short circuit " as the manual explains ...... checked all the motor cables, motor windings, input supply
its connected with a turbo mixer having the specs of the motor as :
45/52 KW
0.86/0.86
50/60 Hz
Has the winding resistance of 0.06 ohms between each of the 3 windings
Would be the case of shorted IGBTs ?
What kind of IGBTs or SCRs are present in this drive ?
thanks
