Hello dadkhah, Understood your problem. But to find out solution, needs aditional information, which I asked in previous post. From the parameter feedback file which you attached in your earlier post, information related with below points is necessary. 1. For speed feedback, tacho as well as encoder is configured. At present tacho feedback is effective. Want to know reason behind configuration of encoder? 2. From PLC 2nd analog input is transfered to drive, which is directly connected to drive AO2. Which is the 2nd analog input (WORD) from PLC? 3. Please check the setpoint (reference) from PLC to drive, is it steady or fluctuating? If it varies, naturally motor seed will also vary. Study the PLC logic how speed refernce is generated? Is it steady? Moreover, simulation of problem conditions in workshop & analysis of site problem is different. 100% site conditions, especially feedbacks, could not be simulated at workshop. Hope this will help you. |
