text: <s>[INST] Powerflex 700s Fault 27 ( IOC ) Intermittent trip Morning all! Hope to get some answers on this re-occuring fault that has us baffled. We have a powerflex700s as the lead drive on a front drum of a winder and are currently experiencing intermittent Fault27 ( Instantaneous Overcurrent ) trips. This drive has been on line for several years without issues but, for the last 8 months, it has been faulting on F27. We have done the following to isolate the problem yet it still trips and appears the frequency of trips is more often. 1.)Swapped drive to spare and downloaded running program. 2.) Autotune3.) Changed Motor4.) Temporary motor cable swap5.) Temporary tach cable swap6.) Lowered parameter 402 from 900 to 300 - PWM Bandwidth We have attempted to run an autotune, and believe to have done so successfully but still trips. We suspect tuning may help us but unsure where to go from here. Any suggestions, correct answers and I'll buy coffee? Regards, Thibs [/INST] first thing the manual says is reduce mechanical load...how did that affect it? \\n </s>
