Hello. About this.. 3 year ago, we have installed into asynchronous motor test centers 230V working controllers. Thus this are testing centers, short circuit in motor or inverter is a allowed condition. All power lines before motors or inverters are equipped with 3 phase reactor and power lines come through ferrite rings. Before motor fuses are 500mA Siemens RCCB-s. About protection the controller: Controller power lines come through main filters, ferrite rings and are bridged with varistors; same (varistors) is with comes inputs where a dangerous impulse can come from. (No UPS-es included on this project) Then.. 3 years of work and no problems found. So Vippi: only protection systems help avoid further problems, ferrites and varistors are a minimum program. |

Here is one of the buffers I saved AttachmentDiagnostic_Buffer.txt (311 Downloads) |

I'm sorry but customer required CPU substitution after the problem because they feared it could be damaged. I have no access to the old one, I saved the buffer when the error occured. I thought the error code was enough to understand what happened.
