  1. load cell SP4M-7Kg

    Hello guys, I have a system of 3 load cells (SP4M-7Kg) attached  to a Micrologix 1500 analog inputs. in the same PLC i have 3 coils for a vibrator, each vibrator is working with signal generators. and the load cells with an external 24vdc Power Supply. i see my load cells readings fluctuating too much even with the vibrator not working. if it is set lets say 70 Grams it is jumping from 68.4 to 74.8 going up an down never never stabilizes in one number, so i suspect am getting noise somewhere put a 100uF capacitor PLC inputs for the load cells but weight just increases more and more. How can realize where is the noise comming? what can i use as a filter? how can i improve this system? should i changed it to digital?   any help welcome! thanks.  questions?

  3. Logix 5000, Array filling

    Hi there! I have a question with AB PLC. My problem:  I have some raw data...distance for example.When the machine starts,the sensor begins to send the information with the distance values. When data is received it is moved into an array. After the first 5 values the program calculates an average and the result is moved into another array.Currently after receiving the fifth value,thus filling the first array,making the calculation and sending the average to the other array,the program empties the entire first array instead of just always discarding the oldest value of the five,and recalculating the average with the newly arrived value every time. I tried to made this with ladder diagram using an an fifo load and unload but isnt working. Please help me if anybody can. Thank You.
  4. I am currently using a Kinetex 5500 Servo Drive with a VPL Motor and its has vertical load attached to it. My problem is even after setting my Brake Enagaged time to 0.01s it drops like a dime. I had made sure that I kept my Servo STO enable for 5 second before MSO is shutoff and MSF is engaged. Any ideas on what I am doing wrong? Attached is an action parameter settings for brake control.
  5. Hi All,  I was wondering if any of you guys could help me about improving my load sharing application. At the moment it's very unstable and i can't see what i am doing wrong! Thanks.  Details: I am trying to run a industrial chain conveyor using Torque control by Real sensorless vector control function of A700 Mitsubishi VFD. I have been following "Technical Note" which is provided by mitsubishi (see attached PDF).  As described on technical note, i am trying to control 5 motors ( 1 X 2.2kW, 4 X 1.1kW) to share the load on this chain conveyor. Torque command (SV) and Motor Torque (PV) read from Master VFD and PID output (MV) of Q03UDE transferred to Slave VFDs over CC-link. i would appreciate any information and help you can provide, Many Thanks.  Application_Technical_Note_Load_Sharing.pdf
  6. I am experiencing a serious problem. Everything went fine in my project for month. Yesterday when I "Transfer to Controller" (like I use to do several time a day) I got this Message : "Build is not complete. Process was aborted". So I build again, I Rebuild controler, I restart SysmacStudio, restart the computer, reset the hardware on the project ... nothing worked. Always the same message. So I opened a previous version of my code. Since it was allready built when saved, I had no problem transfering it in the controler. However, the moment I change a line (have to rebuild) on this backed up version... same problem appear. I finally got to the "output windows" (Alt+3) where I saw ALL build are failed. I've contacted my Omron representative and he is trying to help but he seem as lost as I am. Please help if you can, I am using Sysmac Studio 1.13 on Windows 10. I also have a HMI wired to the project and everything work fine with it.  
  7. I am having trouble loading the configuration into a Micro984-230. I lost an old M84-002 PLC. I have the program. I purchased a Micro994-230 replacement. I lost my cable, so I made a new one. The only software that I have still running is Updoc 4.30b. I tested out my cable and Updoc by connecting to a 984-381. Everything worked fine online and offline. The error I get during the configuration loading is communication error 13. I have no idea what that is. Perhaps I can't do configuration loading with Updoc. I have Modsoft Lite  working but I do not think that it works with this controller. It is for MIcro and Compact controllers. I may have modsoft and taylor kicking around but I do not know if they are installable or not. I hope I can find out if my config is improper, I have used the wrong controller setup file (used Micro984), or where iI can have the config loaded for me? I also do not know if this used controller is functioning correctly.
