  1. Looking for some servo application help. Software: I have GX works 2, GT Designer, and GX Developer.  Hardware: PLC L06CPU-P, GOT2000 HMI, MR-J4-350B servo amps, HG-JR35JK motors, LD77MS2 Pulser I have (2) AC servos that will simply move an aluminum frame backwards and forwards using a FESTO belt mover and I have a servo gear reducer 20:1. I have a "simple motion module"and all of this hardware and software, plenty of time, and would really like to finish this project off. But this is my first servo and my first hmi project. I have some experience with Omron, Mitsubishi, and Allen-Bradley plc's, and consider myself novice at best. Any sample programs or help getting me started would be greatly appreciated!  
  2. Hi everyone, Recently, I started working with the Micro820 Controller Embedded I/O. My project is simple : when the output _IO_EM_DO_00 is set to true, an LED light turns on. But, even though it's super simple, I can't make it work. Here's my setup. If you need more information, feel free to ask anything !

  4. Error 6706 Mitsubishi FX2N

    Hey guys, I'm really a newbie on PLC's, I'm working with a metal sheet folding machine. The past programmer gave me it's code, but I guess he gave me the wrong one. So, I uploaded the program with GX Developer 8 to a Mitsubishi FX2N-32MR PLC, all looked fine until I tried to run out the program. The error 6706 appeared up on step 3928 (blue rectangle). I read something about it already in other posts. But I'm not quite sure what to do. Can someone point me on the right direction? I attached an image where the problem thst showed up.  Thanks. 
  5. Hi,I am new in project engineering and my previous work is PLC programming only. For experienced engineers, what are the step by step procedure that you use in migrating/upgrading and what are the things that I will avoid?
  6. I am searching for the Replacement of the Ultra 5000 Servo Drive as i cant get online to it with the Ultraware software over wireless plant network. In order to get online i have to connect serial cable every time. And the Drives are used in time critical assembly line  kind of environment. So is there any other replacement which works as intelligent as of Ultra 5000 and also have additional feature of built in Ethernet port which can help me to get online with it wireless over plant network.
  7. Omnuc U software

    Hi, I have begun to look into some positioning equipment we have had for a while. There is a CQM1 CPU51 connected to R88D-U series servo drives, and a CS1 with C200HW-NC113 and a R88D-U. I have found WinMon on myomron, but not tried to install it yet, will it run at all on a Win7 machine or do I have to dig out some older PC? Same with the NC unit, there is mentioned a SYSMAC-NCT program in the manual, but I have not been able to find this anywhere, Is this still a commercial item? Are there any newer software that will communicate with these old units? If we decide to upgrade any of this, will we have to replace all, or is it possible to reuse the servomotors or other parts? This is all for educational purposes, no production or safety issues involved. I would of course like my students to work with the most updated systems, but unfortunately we are on a limited budget :( Geir

  12. cannot connect to fx2n plc

    Hi I have 2 fx2n 64MR/MT plc I can connect to one of them without any problem but other one the PROG_E LED is flashing and I cannot connect to it for programming and dowanload my backup to it , its error is aboat cpu type or cable. the battery of this cpu disconnected for 10 days. pay attention that I can connect to other CPU same as it(I said at first). thanks every boady
  13. Hello All, I'm in the process of tuning a motor and I understand almost everything that is happening.  The only thing that doesn't really make sense is how frequency relates to the speed of the motor.  For instance, let's say my 3db point is at 100 Hz.  I understand that from 0 to 100 Hz my motor is stable.  If I have a 3000 RPM motor, how does 0 to 100 Hz relate to the maximum speed I can run the motor and still have precise positioning. Thank you
  14. Does anyone know if the FX2N modules such as FX2N-EX can be used with the FX5U? The plugs are compatible - and the colour is the same ;^) - but I suspect that they may have upped the speed of the bus, or made other changes. Thanks.

    does anyone can help how to connect plc fx2n-16mt with servo drive mr-j2s-40 and motor servo hc-kfs-43 ? please give me wiring schematic thanks a lot
  16. Hi, I am not an advance user of PLC's but I can muddle my way around. I am currently reviewing a program written by another person and I will need to make some modifications. I have noted that on a M8002 pulse the Mitsubishi FX2N-8AD CH5 to CH8 -[To K0 K1 H3333 K1]-  are all set for a 4-20mA current input which is perfectly acceptable however on the same pulse is written -[TO K0 K22 K0 K1]-. I was hoping that someone could explain exactly what this is doing. I understand that the first K0 is the module number K22 is BFM#22 but I am not sure exactly what this is and I am a little confused by what is written in the manual. (8.2.7 BFM #22: Sets convenient functions: The functions described below are assigned to b0 to b3 of BFM #22. When a bit is set to ON, the assigned function becomes valid. When a bit is set to OFF, the assigned function becomes invalid..............) .Due to not knowing exactly what BFM #22 is doing I am unsure why the next K0 is used and the final K1 is to do this operation once? I apologise if this seems like a very basic question but I just can't seem to find any further detail online regarding BFM#22 that I can understand. Any help would be greatly appreciated. Thanks for your help. Paul.
  17. Hi guys, been using this site for a long time, it has come in handy alot. However I have recently taken on my first servo project, heres an overview of the project We have a filling machine that has a separate dosing system to the filler head. It used to keep the dosing in time by adjusting a 0-10v signal to an inverter to make sure that a flag makes a sensor in a set window. I have installed an encoder on the filling head and an mpl servo to the dosing. I have then used an MAPC instruction to follow the encoder, the cam is 0-360 and it follows a straight linear line. I have installed of this as a temporary set up on one of the filling machines (we have 2) and it is working perfectly. I have now installed this on the second machine as a permanent set up with a panelview plus 7, L71 cpu. However it is giving a very strange problem on first power up, the encoder is giving the exact same position as before it was powered down. however as soon as the MAPC executes the servo axis  faults, giving an overspeed fault. the servo doesnt even look like its attempting to move (however it is through a 10-1 gearbox). if i then home the encoder it then runs absolutely perfectly until it is powered down again. I am beginning to think it may be to do with the master lock and cam lock position, as the cycle stop position of the two machines are different. however I just cant seem to get my head around i the difference between them.   Hopefully that makes sense any help would be greatly appreciated Thanks Rhys   c1_dosing.ACD

  21. Beginners Servo Help Required.

    I have been programming Omron plc's for a while but have not used any servo drives. I have customer who is free issuing the following equipment for a project he wants programmed.: cj1m cpu21, r88d-gt04h, r88d-gt08h, r88m-g40030h, r88m-g7503h-s2. The small drive is connected to a simple ball screw moving a stop. The second drive is connected through a gear box and chain drive full details not known to date.  I have read the cj1 manuals and will be generally using  pls2 commands for the position movements.  Are the drives plug and play? If I connect the drives leaving the parameters as out of the box defaults should the drives operate using the pls2 command. In this condition I assume it is 10000 pulses per rev of motor. I can scale positions with maths in Plc and send the required pulses. Any guidance appreciated to confirm I am on the write track. I assume I could also use the electronic gearing parameters. Any examples using 5mm ball screw!

  24. Hi... i want to ask about QD75D4, how to change rotation direction in positiont data ? If position data number 1 is CCW and position data number 2 is CW.   I try give value 100 (hope run CCW) and -100 (hope run CW) on posiition length but not respond.   Parameter axis #1 Control system = 2:INC linear axis   Any setting mistakes ?   Thank you
  25. Please suggest me about these issues: Issue: No Rotation 1.     The motor links are slack or release. 2.     Distant issue is stuck in the glide. 3.     The motor load is extreme. 4.     The bearing are shabby. Issue: Overheating 1.     The rotor is in part demagnetizing cause extreme motor present. 2.     Motor voltage is exceeding the highest value. 3.     The duty cycle is extreme.
