text: <s>[INST] Kinetix 6000 Fault E37 while machine is not moving I have an issue with a group of Kinetix 6000 drives displaying an E37 (Power Phase Loss Fault) while waiting on command to move. I have checked and traced my power for the Contactor that enables the 480 VAC to the IAM module and i maintain power up to the module itself. It seems that the Contactor Enable relay in the IAM is telling the contactor to turn off. I am unsure why and I am unfamiliar with this series drive. Looking and researching, i think it might be a drive in the same rack but how can i tell? I have access to Studio 5000 and have been looking thru the bits to see what is toggled. Any and all guidance will be appreciated. [/INST] Hi Joshua, E37 occurs after the AC Line Input Sensing Circuit senses a loss of one or more phases; if all 3-phases immediately, or if one phase is lost for 2.5 seconds. E37 can also occur if the customer is using a multi-axis system without an axis assigned to the IAM and/or the Motion Group. When an axis is enabled, that axis and the IAM show E37. E37, Power Phase Loss Fault on the IAM cannot be reset without cycling power. The IAM must be in the motion group to prevent this fault, either with no motor or the correct motor selected. E37 is not a selectable fault action in RSLogix 5000 version 15 but is in version 16. To avoid this issue, associate an axis (in the Motion Group) with the IAM, but configure the axis for no motor, or have an actual motor connected and configured to the IAM inverter section. \\n </s>
