Fault Value in r949is 2. Manual didnt have any information for Fault Value 2 Strange thing is, Drive is tripping even in SLVC (P1300=20) on same fault Regards, Devesh Vithani

JensS Posts: 739 Rating: (55)	pls have a look into this FAQ: Why does my drive not stop with F0090 when an encoder wire breaks when used in a differential connection? http://support.automation.siemens.com/WW/view/en/22795432 Why are fault messages F00453 and F0090 present although the encoder module was correctly parameterized? http://support.automation.siemens.com/WW/view/en/24167699

Because, normal practice to check encoder feedback is to run drive in openloop and check feedback in r0061. Does this make my drive trip on this fault?? Devesh
