  1. How long  could be INT array. For example can I build INT[365] or DINT[365]? When I use more than [32] my controller fails. Thanks. 
  2. Good day everybody,    Currently I am working on an application using 3-axis controlled by a QD77MS4 Simple Motion Module.  In this case, I have already set up most of the configuration, but when I try to execute the program, I get the following error:   SP. UNIT ERROR - The location designated by the FROM/TO instruction set is not the intelligent function module/special function module.  - The module that does not include buffer memory has been specified by the FROM/TO instruction.  - The intelligent function module/special function module, Network module being accessed is faulty.  - Station not loaded was specified using the instruction whose target was the CPU share memory.   The QD77MS4 Module is mounted in Base Slot #3, so I use U2\G800, U2\G1500, etc... to Read/Write from it.  The Diagnostics tool indicates the error occurs as soon as I try to access the U2\G800 Buffer Memory. If I set this part of the program to No Execution the error is no longer displayed.  Additionally, if I try to monito the Buffer Memory area of the Module, it says that "The Module Stat Address is incorrect".   I already tried changing the position of the module in the base (Slot 3 --> Slot 1) and changing the corresponding values to reflect that, but still the problem persists.    What am I doing wrong? Is there some kind of configuration I could be missing?    Thanks in advance for your help!   
  3. Hi everyone, To explain the problem a little bit: I have 2 systems that are equal, they have 1 PLC, 1 Inverter and 1 Servo Axis (Image01). The devices are connected via EtherCat. The thing here is tht in these systems the PLC and Servo Axis is the same but the inverter is different. My goal is to have the same project on both systems and depending on the inverter detected use the correct program. What worked: If I add the 2 Inverters and 2 Servo Axis on the project on different nodes (Image02), I can detect which is present using the variable _EC_EntrySlavTb[n]. My issue is that if I want to make more replicas of the systems using different inverters I will eventually hit the Axis Number limit for the PLC while in reality I am only using on Servo Axis at a time. What I wanted: I would like to be able to control 1 Servo Axis with 2 different inverters (only one active per PLC) (Image03). What I tried: The axis parameters can be set using a variable of the type _sAXIS_PARAM, however it seems that the option to change the axis basic settings is not available (Manual: NJ/NX-series Motion Control Instructions Reference Manual (W508) page 5-58) (Image04). The axis basic settings is where the definition of the output device plus control words are set (Image05). Is there a work around to solve this issue? I would really like to avoid having to manually change the output device for the Servo Axis every time I make an update on all the systems.   Best Regards, BR  

  4. simple motion cam curve

    AndersonJr posted a topic in Mitsubishi

    Good afternoon, I have a problem in an application for a rotary knife, I'm using a MR-JE-B servo to make this movement, while my material is powered by an inverter connected to a modbus rs485 network, with a 5v encoder connected directly in motion. I'm having some problems and I think it's my cam curve. I have a very high refeneration, and the system doesn't obey the size of the length I want the cut. It always cuts the same size, regardless of the configuration I use, it always cuts to 245mm. Put some photos, how are my settings. Grateful in advance, if anyone can help me.

  5.  What is the difference between Active Immediate homing and passive immediate homing ?   Does Motion servo axis have to be turned ON for active immediate and turned OFF for passive immediate homing ?.
  6. I have seen some programs in which they manually unlatch all bits like in figure 1, and in some programs they don't do that.  The instruction help page, ladder execution says that in pre-scan .EN, .DN, .ER, .IT bits are cleared to false So do we need to unlatch all these bits before giving a motion command like MAM ?  
  7. Hello everyone, I have this weird problem that the PC (process complete) bit of MAS command does not clear after a cycle time.  As you may probably see in the picture attached when the desired torque has been reached, the servo has to be stopped using MAS command; however, this is good only for one cycle!! The PC bit will remain on even when the whole sequence gets unlatched/reset. I have to manually reset this bit. I was wondering if you could help me with this issue, please?  Thank you!  

  8. MT Developer 2

    Willard posted a topic in Mitsubishi

    Good day everyone, I am working on a problem on a Mitsubishi Q series PLC and motion system. The system consist of a Q12H PLC CPU and 2 x Q173CPUN Motion CPUs. The first motion controller controls 23 x MR-2JS-_B Servodrive and thesecont motion controller CPU controls 6 x MR-2JS-_B Servodrives. They are all using SSCNET1 system.The machine have been working fine all along until the machine stoped for 3 months because we were waiting for one spare part that was coming from oversees during covid lockdowns. When we restarted the machine, the servodrives could not home. When we were busy checking for the problem and before finding the problem, the machine just started homing. This keeps on happening over and over. Everytime you stop the machine overnight, it just stop working then when you are busy troubleshooting, it just come to like. In the time when it is not responding, we figured out that when we jog the servodrive controlled by second Motion controller CPU for the HMI, the drives jog fine but the servodrives controlled by first motion controller CPU does not respond. I have tried jogging the servodrives indipendently using Setup161E and they move . I even changed the motion CPU but to no success. When you monitor using MT Developer 2, the are no errors. Is there anyone who might have an idea on what might be the probable cause    

  9. NX1P2 Motion Control

    simonongsk posted a topic in NJ Series / Sysmac Studio

    Hi:       I need to change an old PLC  with NX1p2  to control 3 servo motor by means of Analog Outputs couple with encoders, My job is to change the PLC only. So the servo drives and drivers are untouchable (No budget and involve too much mechanical works).   I observed that Sysmac Sttudio Axes setting has this: Servo Axes, Encoder axes, Virtual Servo Axis and Virtual Encoder Axes.   I believe the Encoder Axes couple with Analog Output is able to to do the Job? If so, what function block should i use? If no, do any body have a suggestion of any function block i can use? Thanks  

  10. CJ1M con CJ1W-EIP21 a ControlLogix

    Eduardo Juarez posted a topic in CX-Programmer

    Hello I am trying to communicate a CJ1M with a CJ1W-EIP21 Card, with a Logix Control, but I have not been successful, what I am looking for is to read data, from the OMRON and see it in the Logix Control, but I have not been able to establish communication, I am looking for someone You will already have a functional example, with the backups of both PLC'S, to be able to observe how they made the configuration. Thank you for your support Greetings
  11. I'm having trouble with some Powerflex 525 drives. Right now what I need to do is run them manually from the keypad to test conveyor belts.  Is there a way to do this and if so how?   Thanks in advance.

  12. Motion Perfect controlling servo

    MacroPc posted a topic in Other PLCs

    So I'm new to the automation scene and in my training I decided to setup a little test rig, plc, drive, servo, sensor, hmi...etc.  Everything is wired and hooked up. What I'm trying to do is simply get the servo to spin. here is a screenshot showing what I have. I think there are some flags on the servo itself that need to be set but I'm not sure how to do that. In Base(x) I have tried 0, 1, 4, 5, 35. Any help would be appreciated.
  13. Hi everyone, I have an annoying fault on my Kinetix 5700 drive: M01-Safety Feedback. I know this fault is generated by  the SFX instruction in my Safety program that sets tag: "Axis.SFXFault" to 1. The problem is that the instruction is NOT in Fault (Fault code 1 = no fault). This error occurred after Safety encoder 843ES lost it's IP address. I used Bootp to set it gain. And reset the SFX instruction. I can see the encoder in studio 5000 rev 32.12 running and ok.  Does anyone encountered this problem? How can I clear the fault?   Thanks
  14. This is hard work! I've installed the CODESYS OPC Server V3 in the hope of using it to communicate with my Schneider PacDrive LMC. Apparently the PLC doesn't support OPC tag browsing so I need to export the symbols from the SoMachine Motion project file in a format that the OPC server can use. I've got the Symbol Configuration panel open and can see the symbol tree. What do I do next?
  15. Hany any you of guys dealt with MDS instruction not completing and being stuck on .EN bit but the motor itself just stopped running out of nowhere? I did read the tech note on this on Rockwell's website. Am mostly wondering if any of you have dealt with this and what you did to fix this.
  16. Hello Everyone. We have Schneider TM241 PLC Along with Citect SCADA System at 100MWp Solar Power Plant to monitor and control various equipments like Inverters, Switch-Yard, MFMs, Weather Monitoring Systems etc... Government Authority here asked every solar plant to control the generation as per the instructions by Load Dispatch Center, for that we need to implement logic to control Generation as per requirement. For that we are controlling generation from inverters by giving them generation setpoints calculated by PLC using PID function.   But we are facing one problem while using PID. (FB_PID of Toolbox Library)   Suppose we need to generate only 60MW out of 100MW. So we set PID setpoint to 60MW and according to that we get PID output and according to that PID output value we provide generation setpoint to every inverters.   This system works very fine until the clouds comes into the picture.   Now suppose Setpoint of PID is 60MW and PV is also near about 60MW, and suddenly large cloud comes over plant and block solar radiation.   In this case generation comes down to 10MWp(or any value below 60MW), So output of PID will Increase and keep increasing and settle at the Maximum value. but without solar radiation generation value stays very down then Setpoint.   Now suddenly Cloud moves and again solar radiation increase, but the PID output is maximum at that time so, Suddenly Generation goes from 10MW to near about maximum capacity (100MW) instead of 60MW, and then it will slowly comes down to 60MW.   We need to rectify this generation shoot up when cloud moves. Anyone have idea how can we solve this problem or anyone have programmed PID in this kind of situation.   Is there any function block available to do this correctly like function block of PID with two Reference or something like that...   We are using TM241 which is CoDeSys based PLC.
  17. Hello everyone, I have a Kinetix 6000 CIP drive (unwind) and I need to control its speed by a PID controller. I have everything working except the MCD instruction doesn't pick up on the PID output value change. It changes the JOG speed, which I use to control the unwind, if I set the speed manually, which is slow. The PID changes the speed almost continuously. Any suggestions are welcome. This is how I'm attempting to control the speed: A1_r_JogSpeed = PID output value   Thank you    
  18. So I'm having trouble writing a FBD within my current program for a slitting line. I need to keep a constant tension on my web as it is being recoiled onto our recoiler. I wrote a simple program using a sensor to read the growing rate of the coil to get a radius and I have feedback on my torque on the recoiler motor. The simplest math for this application without getting into anything too fancy should be Tension(lbs)= Torque(ftlbs)/coil radius. only problem is when its less than a foot then my calculation is thrown off and it actually shows tension goes up until it reaches the one foot mark then it seems to scale correctly. Do I need to scale something else? Any help on this would be appreciated.
  19. Hi all, I am studying how to control servo with PLC Mitsubishi Q-series. When I click Servo_parameter in Simple motion module setting tool, this annoucement appears.  Does anyone know why it appears? I tried reinstalling MR-configurator 2 but it didn't help. Please give me some advices. Thank you all!

    Niteen posted a topic in Mitsubishi

    Hello Guys,                      can anyone help me programming of FX5-4LC temperature control module with FX-5U80MT PLC. I want to Read present temperature value of each channel and want to set Temperature Set value from PLC.
  21. Hi Every one, I have two 2198-P070 bus power supplies for that I’m using for four Kinetix drives, 2 drives per power supply, all controlled by one processor (5069-L350ERMS2). I have an enable contactor setup for each power supply for each set of drives. I have them configured as DC bus groups 1 and 2 respectively. I had the first set of drives working, setup inside the motion group, with no issues. When I added the second power supply and drives. I found that when I added them to the motion group I couldn’t get the enable contactor to close for the first set of drives. I f I took them out of the motion group and made them ungrouped then the first contactor would close but then I couldn’t get the contactor on the second set to close. Do you have any thoughts as to what I might be missing to get these to work? See the screen shots for more detail. Let me know what you think.  Also, I have heard that only one motion group is allowed per PLC, but my question is : Can I use  sevral axes and Power units in the same motion group? 
  22. I am desperately trying to understand the OMRON way of programming (28 yr. AB programmer) when it comes to Motion Control.  I am pouring over example programs and what I can understand in Omron manuals.....  What I cannot find is where you get all the bit level information from for individual axis....  For example, just a simple bit signaling a Servo Fault; I have a program that I have been studying and there is a bit with the variable MC_NailPunch_Station.MFaultLvl.Active, it obviously comes from the Axis "MC_NailPunch_Station", but I cannot find the reset of that variable anywhere in the program, in any setup....nothing. Is there a list somewhere of things like this I can use in my program for status bits etc.?   Thanks,

  24. Control Panel

    cjcygan posted a topic in CX-Programmer

    Is it possible to view the values / states of all inputs, outputs and workbits (e.g. 64.00 through 64.15 on Omron CQM1 PLC) on a single screen or control panel within CX-Programmer software?  I'm trying to troubleshoot some ladder logic that I wrote and need to know the values of 5 or 6 inputs/outputs/workbits simultaneously.  Having to scroll up and down through my ladder logic repeatedly does not work well with code that changes state every 5-10 seconds or so. Any help is welcome.
  25. Hello  We have just purchased some equipment with a Control Logix 5561 (1756-L61/B Rev 13.40). The compact flash card is missing from the unit but the seller says the unit was running in his facility prior to shipping. Does the 5561 have internal memory where a program is stored? Is the Compact Flash used only for recipes and persistent data? Thank you
