  1. NX1P2 Motion Control

    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  
  2. 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.
  3. I have been working on a PLC project that requires sending ASCII commands/queries to an external pressure transducer using the Micro 850 PLC (2080-SERIALISOL module) via serial port communication (ASCII protocol) and in response the PLC would read pressure readings from the transducer. I was able to write a ladder logic program that reads ASCII code from the transducer and converts it into string and inversely converts string output from the computer to ASCII and sends it to the transducer. However, I am uncertain as to how I should send the command string from my computer so that the external transducer receives it, recognizes it after the <cr><lf> is encountered and sends a pressure reading. Any suggestions as to how I can type in commands from my computer and receive responses from the transducer?
  4. 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
  5. 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?
  6. MDS instruction would not complete

    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.
  7. 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    
  8. 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!
  9. 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? 
  10. 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,
  11. Commands Protocol

    Hi all, I would like to ask you about the name and manual of the command protocol for PLC Siemens.  I am not asking about communication protocols, I am asking about the protocol of the commands to use some features of the PLC without TIA Portal. In a similar way, OMRON is using the protocols FINS and Hostlink, or Mitsubishi is using MELSEC commands. Thank you very much.
  12. Omron Force Bit Cancel via Fins

    Hi Everyone, Sometimes I forget to cancel forced bits in omron CJ2M-CPU34 PLC. I want to cancel all forced bits automatically and found something about fins command. I'm now facing difficulty in activating the all cancel forced bits command. (2302) Is there anybody know how to use @CMND command for cancel forced bits?  Thank you.  
  13. Hi all. I have a Kinetix 350 and an AB TLY servo motor. I'm using the drive's STO function. AC power is supplied into the drive, passing through an "M1" contactor. It makes sense to m e to keep that contactor open, preventing AC power to the drive, until the drive is fully awake.  Is that what you guys do? Someone suggested to me in another forum ( http://www.plctalk.net/qanda/showthread.php?t=121021&highlight=drive+awake ) that there is no reason not to supply power to the drive right away because the STO function is inhibiting power to the motor anyway. 
  14. Bonjour, Hello, I use a l33erm automaton and a Kinetix servo motor . This servo motor drives an engine with a chain moving in steps of 100 millimetres (there are 15 steps on the chain ) At each top of a cell this motor advances by 100 millimetre. in reality it advances from about 0 to about 100. Sometimes it is 100,002 times to 99,997 (this is important further) and when I give it a top it goes back to about 100 (100,003 times to 99,996) And so on and so forth up to no problem, I use a MAM with an absolute type of movement. It works.     However, this does not work any more after a rearmament following an emergency shutdown. if it is a 100,002 no problem at the next top the chain advances one step But when the engine is shut down at 99,997 and I give it the order to go to 100 it advances only by 0,003.  This only happens after an emergency stop (or door opening). Thank you for the help you can give me excuse my English this is a machine translation Un séjour sans faille
  15. Hello,, I have motion controller A series A172SHCPUN,, I have written the program ladder into the CPU, but I can't write the motion program.. i dont have the program to open file the program motion and I want to ask if I have the software SW3RNC-GSVE, my os computer is window XP, Can it be installed? and is the cable transfer used the same as the ladder transfer program cable (SC09)?
  16. Hello, I have an interesting problem that no one in our company can really answer for me.  We are using Drive Logix with a powerflex 700S phase 2 drive and controlling a machine that rotates 360 degrees, sits for a moment, then return back to zero degrees.  We are using the MAM instruction to tell the drive to run the motor to its desired degree.  The problem we seem to face, is when they change jobs, the weight changes and we have to adjust speeds in order to get the machine to rotate back up to 360 degrees.  Otherwise, the motor stops short.  It usually never faults or alarms, it just stops short.  For example, they might run it and it will stop at 240 degrees or 315 degrees rather than the 360.  My question is, why doesn't the drive continue to push the motor to 360 degrees?  Why wouldn't the drive fault out on something like over current?  It seems that it just stalls and stops.  Sometimes, the machine will be running great, but on occasion (1 or 2 times a shift), the machine will stop short again.  I am curious what causes this and how I might be able to fix this to force the drive to continue to try and get to that desired degree. Thank you for any help or input!

  19. From PM this morning

    Fairly new programmer doing first analog section in project at new job. Im using NCF motion with parameter for torque control to send the torque values  a+8 (leftmost word) and a+9 (right most word) to CX programmer. From there is where I get confused will I just simply be moving both cio 108 and 109 to to a D register?? or will I have to combine the a+8 and a+9 to make a Dword??? and then taking that value to HMI broken line graph. sorry again for creeping in your inbox but ive been looking online for 6 hours. would greatly appreciate any help
  20. Hi, I am trying to do a merge move on 1S Servo. The condition are as follows: Task: Move 2 in(absolute value) and then Move back to 1 in (absolute value). I have to do this move 10 times in a row.  The application is material leveling after dumping in the mold. The only question i have is if I use just MC_MoveAbsolute command, the only buffer mode for transition available is velocity. Is there a way i can do it with position. I dont want to stop when I can go from 1 to 2 and 2 to 1 again and again. Its time consuming. But rather a nice oscillation motion without stopping to mimic leveling. Can anybody please help me out with this problem.   Thanks
  21. Hi,  I'm new to TwinCAT 2 and i'm upgrading a long time design (hence the TwinCAT 2 reference), to read a more sensitive torque signal.  I'm using a Beckhoff CX1030 as my PLC Controller.  I needed to add 'homing' to my motor sequence and confirmed with Maxon, im using the function blocks correctly and in the correct sequence to establish my 'absolute zero'/'home' position.  The motor has an output to write to:  ControlWord, which tells the motor that the position it is sitting in is '0.'  My program compiles, it runs, it writes each function block, but it's not seeming to get back to the test run opMode, even though i tell it to and the function block performs the 'Write' function.  it's stuck at zero and not reading an analog input signal from my torque sensor.  so im getting an artificial torque reading through every test.   i think this is related to my tare motion.  I start the program, home the motor, get into profile velocity mode, tare my sensor, enter profile position mode, go back to position 0, then back to profile velocity mode, run a test, sample data, go back to 'home' or '0.'  I wonder 1st, is my variable not linked properly through the system manager?  2nd, i set a boolean variable to set the 4th bit to 1 in my control word write (setting the 4th bit high will set my current position to absolute zero), but did i not connect the program to the main sequence properly?  looking to read a valid signal again and see that my motor moves back to 'home' each time.  Do i not need to home the motor after the tare, since the tare nulls out the torque value after the tare? after this i need to program my sample period, instead of it being fixed, as it is currently written and then use my home position as my trigger to start sampling.... Beckhoff applications department is overloaded, currently and can't help and this is all beyond the knowledge of the general support line.  I've gotten fairly far, on my own, but of course, the project is under a time crunch.   Does anyone know twincat well enough to help guide me?
  22. RS logix 5000 motion control

    Hi Guys! I have a problem with Motion axis move (MAM) command. There is an Allen bradley servo motor what is working well. But I need to add a new program section, wich is in  a specified moment, the axis should move a certain distance. I think I need to use the mam command, just I dont know how can I configure the motion control part. I need to make a new tag ? or what ? I need to use a user define ? PLS help me.   
  23. 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!  
  24. Hi Here's a question I'm about to ask Omron.. as soon as I can figure out who to ask.. It's complicated asking support.. their web email form doesn't make complex questions easy. Here's the question: Can the NJ CPU program a LinMot linear motor to make the "Random Sea"? The NJ has a mixed protocol.. Ethernet/IP and EtherCAT (CoE),  and claims to be a "Motion Controller".    I doubt Motion Control is available on it's Ethernet/IP line.. but the EtherCAT might be another story.   Certainly The Omron NJ is a Motion Controller for Omron NJ series drives.. However, how well does it work with LinMot? Here's the curve.  Imagine a LinMot Linear motor continuously moving, never really stopping, following a real-time, mathematically generated curve, moving positive then negative, at random frequencies and random amplitudes. Almost never repeating a motion sequence. looks something like this: Yet, after a while the motion history fully represents the spectral distribution of energy on the surface of the ocean. Spectrum analyzers can display it, and mathematics can define it..  I just have to make that sea in a model scale…    (Time scales by the square root of the scale factor) And keep the water in the tank: https://www.youtube.com/watch?v=SQd6YzBWVvI The big question is: Can the Omron NJ get a LinMot Linear Motor to do this? … LinMot thinks YES.. but, isn’t sure. Yes there are ways to “connect" LinMot to The NJ.. EtherCAT (CoE), Ethernert/IP but… there is nothing in the LinMot drive that can create or store a predesigned Random Sea .. Only a Motion Controller, generating real time motion commands, by running  mathematical equations, "on the fly” can do that.   If the NJ is a true “Motion Controller”, and the LinMot C1250-DS-XC is implemented as an “axis” by Symac Studio, which it is…       Then, there may be hope. Closed loop, PID feedback remains with the LinMot drive, with special settings in LinMot Talk … Homing might have to be done with the NJ .. or by Digital I/O’s What do the Omron experts out there think?  Can this be done? Thanks much, Regards, Michael
