Hello engineeeer, From the details you provided, please check below points. 1. Servo motor 1FK6100 is with resolver feedback. 611U control card having encoder 1Vpp interface. Question is how motor resolver feedback is interfaced with control card? Does it has any in line converter? Please check. 2. You mentioned encoder 1Vpp is interfaced, (encoder part number is not clear) Here I presume it is external encoder, & interfaced to second encoder interfacing port on 611U card. Please confirm. 3. You have not specified type of controller. Is it Sinumerik or PLC controller? what is application? Positioning or speed control? Please check. In general, loud humming noise from motor is indication either due to load or variation in setpoint. Depending upon active feed back system, please check motor resolver, encoder connection, proper out put etc. etc. If you have same control card for another axis, try by swapping it. Check motor winding resistance, motor cable, LT module etc. etc. Check if motor/axis brake release, i.e. if motor has integral brake, check by providing external supply to brake & observe if any change in sound.If it is Sinumerik control, check if Contour or standstill alarm is triggered. If possible try by decoupling motor from load & check. If everything above is good/OK, check lubrication & try by adjusting drive/axis gain values. Hope this helps. |

Hello dears ; the simodrive system is connected to plc through profibus not sinumerik system. Encoder has no serial number (name plate ) so i don't know it. The drive has no internal break. The system is positioning mode. Please find the attached pics Attachmentsimodrive.zip (935 Downloads) |
