Hello guys, today we had a problem in a MASTERDRIVES AFE we have in the company ( Quay Crane) , in order to perform control of AFE Hoist 2 (Slave) , and was going to 029 fails when the command is found off or logo after off it. As the fault manual indicates that it is a possible fault monitoring phase , probably carried out by CT . Therefore, use was made of Testbox MASTERDRIVE , and performed at the CTs offset measurement , and the related T phase ( L3 ) is with values above 1,500 M Ohms , while demics had between 80 and 90 Ohms . Even with this report, it has not been done to change the CT . The question is , the CU 029 has a failure , with no load equipment, ie , off ? How is this possible? Will could also be a problem with the IVI board, like a bad contact in your post , causing a bad feedback monitoring ? Thank you for attention. ------------------------------------------------------------------------------------------ |
