Hi friends, I'm facing problem with Analog Input 6ES7331-1KF02-0AB0.. The problem is the value I got is very fluctuating / not stable when I connected a Pt100 sensor. The following steps already carried out but no result so far: 1) RTD signals wiring connections as per module wiring diagram, earthing and shield earthing are OK. 2) The motor is driven by sinamics S120 drive and motor capacity is 110KW and siemens india make. 3) we have total 5 nos. of motor and their RTD signals are connected to remote RIO panel where Analog input cards are mounted and each motor having 6 RTD signals and it is connected to 1 no. of Analog input card and vice versa. 4) we found motor no.5 RTD siganals are OK (without any fluctuations) whereas all other motor RTD signals were having fluctuations. why?. what is the reason for this? 5) I also noticed that whenever motor running, that time only fluctuations are coming and if motor is idle, RTD signals are smooth. Please kindly help me to solve this issue on emergency basis. Thanks in advance. In case further any informations required, please let me know. Regards, K.Kadhar Mohideen How can I reduce the resolution of this analog input, so I can get a smoother reading? AttachmentWT1_INDEXER_ALL_MOTOR_RTD_TRENDS1.pdf (407 Downloads) |
