text: <s>[INST] Ultra 3000 error code 44 Is there an explanation of error code 44. The tech note i looked at references something about the current power cycle which does not make sense. What will cause the fault and how can you reset it. Does it require that you power down the entire system to clear it. [/INST] Prevention: Maintain encoder signal integrity, eliminate noise sources. and thats kind of a mash up a couple knowbase docs 36307 and 36895 When a lost motion fault occurs, the nonvolatile, absolute homed status (and Logix absolute reference) is cleared only if the drive has been homed during the current power cycle. This is because motion may have been lost prior to establishing the home position. When motion is lost and then the drive is homed, the home position will appear to change on the next power cycle by the amount of lost position. Therefore, the drive must be power cycled and then homed again. If the drive is homed, but not in the current power cycle, then the nonvolatile homed status is not cleared and only a drive reset is required after a lost motion fault. The drive will be correctly homed after the power cycle/reset. This applies to single and multiturn devices for stand alone and Logix applications. \\n </s>
