  1. I am looking for how others have set up vertical axis motions using the Kinetix 5700 servo system. I have a 2 axis pick/place unit with a horizontal axis (X @ 2500mm) and vertical axis (Z @ 1200mm) that works as designed during normal operation. X axis has no holding brake and Z axis has a factory installed 24vdc to unlock brake. There is a GuardLogix L81ES control system that handles the safety and control. On pressing E-stop/opening Gates the vertical axis will stop the motion, apply the brake and hold with no problems. (2198-D032-ERS3 Drive, 2198-P031 Bus Power, MPL-B430P-MJ72AA X Axis, MPL-B330P-MJ74AA Z axis) The issue that I ran into was an accidental download of the program without activating the e-stop and the vertical axis dropped unexpectedly when entering program mode on the processor. I am aware that this instance was my fault as the programmer, however I am also concerned that this might occur again in the future if the controller ever enters fault mode or someone else completes a download. I have done some investigation with the "ProgrammedStopMode" parameter on this single motion axis and attempted all 5 options and the vertical axis still has a free fall drop for a second before the brake grabs hold - so evidently this is not working for me. (Page 24 of Vertical Load/Holding Brake manual - https://literature.rockwellautomatio...t003_-en-p.pdf) I am curious if there needs to be something done elsewhere as the X and Z axis are set up as coordinated axis? I also am unaware if I need to preform some action/parameter with the bus power supply for this? The current state of the machine as it sits now is preforming a MSF in manual mode after 5 seconds of inactivity or 30 seconds in auto mode. This axis is usually in demand every ~22 seconds. This will shut down the axis after preforming a brake test on the vertical load and seems to function OK, however it is still in the back of my mind the issues mentioned previously if we ever enter a controller fault while indexing. Thanks for your insight
  2. 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    
  3. HSPsO

    I am using fatek FBs 32MN PLC. i need to run the nema stepper motor synchronized with induction motor's speed with some ratio. in my case the speed of stepper motor will change as the speed of induction motor changes its speed, may be many times in a second. Problem is that the speed of stepper will be constant as before until i have to disable and then enable again HSPSO function. is there any solution that i can dynamically change the speed of stepper without disable and enable HSPSO function ?
  4. Hello Everyone, I am struggling with interfacing Incremental encoder with FX5U PLC, Does anyone have parameter setting and sample program for same. i am unable to fetch counts...   Encoder: 500ppr, 24V line drive, A-B phase,  PFA datasheet
  5. Hello all I am have FX3G PLC, where i am trying to use SPD function for speed monitoring and controling. currently i am working on software only.

  6. Hello there, I am using a Kinetix 5700 drives to control bunch of axis. HW used : 5069-L320ERMS2 GurdsLogix, 2198-S086-ERS4 Servo Drive with MPM-B2152M-M motor and the 843ES-SIP12BA6 safety encoder. All is working fine except I can't figure out how to dynamically change an axis velocity  controlled by a MAG instruction. I have a virtual master axis controlling the velocity and each physical axis is controlled by a MAG instruction with a gear ratio. In my safety program I have SFX and SLS function block used to determine the safe speed limit. The  SLSLimit output of the SLS function block is linked to a SS1 Request of my servo drive. This causes the axis to stop when safe speed limit acceded.  What I'd like to be able to do is to dynamically change velocity (limit it to safe speed if SLS instruction is active) of each axis without having to change the gearing ratios and thus avoid the SS1 safe stop action.  I know how to do that using JOG or MOVE but is it even possible to do that using the MAG instruction? Regards Martin
  7. FX5U high speed counter

    Hi All Does anyone know if it's possible to simulate the HSC function using just the software? I'm using the Hioen command but I want to try and simulate it if possible. Thanks in advance Scott
  8. Hello guys, I am running an application for packaging measurement using a sick DFS60B incremental encoder (programmable from 1 to 10000 PPR). In more detail, it passes packaging on a conveyor belt and we have created an inspection station and an expulsion station (defective packaging), so we use the encoder to check at specific points of the packaging for defects (we use special sensors to check defects). ) (there are four in total). However, the problem we are having is the following: When reading the encoder in the PLC, the same means that performs "jumps" and does not enter the windows (GRT and LES) created on the ladder, ie, as if it were not continuous. . I understand that because the VHSC24 card works at 1 MHz in counter mode, this type of problem should not occur according to our application is not even 100 KHz. For example, our case: Using 1000 PPR and the motor speed (coupling output) is 3600 RPM (in practice it is around 1750 RPM) the frequency is calculated as follows: F = (PPR X RPM) / 60. : F = (1000x3600) / 60 = 60 KHz, ie 60 KHz is much less than 1 MHz, I think this kind of problem does not occur. Application Info: . Studio 5000 V31 . PLC Model: Rockwell 1769 - L19ER-BB1B CompactLogix 5370 . Encoder Card: 1734-VHSC24 / C . Incremental Encoder: Sick, DFS60 up to 10,000 PPR and HTL Electrical Interface. Using a 200 mm circumference / perimeter wheel. . Motor Nameplate Data: 1670 RPM, 0.37 kW / 0.5 HP, 60 Hz . Inverter: Weg CFW500, Output Frequency 62 Hz. Card Settings we use RPI: 2 ms Type: Counter, but we already use it as Encoder X1 Store Count Mode: Disabled Filter: No Filter, but we use 50 KHz and 5 Khz filters in our tests. Counter Attenuator: 1 Wiring Diagram VHSC24 We turn on encoder A at input 0 and encoder Aret at input 1 In logic (Structured Text) Using the PMUL instruction to convert encoder (Pulse) data to mm scale. (Ladder) The window comparisons part (GRT and Les) and other part of the process. We emphasize that we performed the tests also only with the reading and comparison part of the data, excluding the other parts, precisely to verify the issue of Scan, but the problem persisted. If anyone here in the forum has some information that can help us, I would appreciate it.
  9. Hello everyone, I have a problem with packing machine. There are some issues with one of the axis, when axis actual position is near to 1800000 some error appear and operator has to turn off machine on main contactor. This axis is working in Linear mode. I think that rotary mode would be better for this axis. And here is my question. Which instructions, and what options i should change/check when i change count mode in axis's options. Can any1 point me some manuals to read or give me some advice ? Thank you in advance.  
  10. Hi, I can’t find an answer to the following and I was advised to ask it here.I’m programming an Omron CJ2M with an MD212 high speed I/O card. I usually do all my programming in Structured text, simply because I like it a lot over ladder or sft.Now, if I want to read the hight speed counter (incremental encoder), I have to make a ladder section and use the PRV instruction to store the present value in a chosen location.The manual says the current PV is stored in A271, but I can’t get a readout there. Apparently the only way to read it is through this instruction.Does anyone know if there is an equivalent to the PRV instruction for Structured text? or another way perhaps? Again, when I check the actual memory adress, there’s no value there withouth the use of the PRV instr.
  11. I am controlling the powerflex 527 drive with MSO instruction, first setting the drive on and then running the motor with MAJ instruction. After MSO instruction, motor is rotating about 2 sec and then stops to wait the  MAJ. I have not find any solution for this. My configuration is frequency control, no feedback, sensorless. One hint i found from the rockwell pages but it did not help me. Rated slip speed is set to zero.  
  12. PLC occasionally going out of Run mode?

    Has anyone had an issue with Siemens plc's occasionally going out of run mode? I was doing some research and found that it could be due to a bad analog input. Is there a way to tell which input or output is causing this fault? I know I can create a hardware diagnostics error organization block but that only correct from what I've read.     Edit: I've added a screen shot of the diagnostics report. The fault that may be the problem is: Temporary CPU error: Serious firmware exception  CPU changes to DEFECTIVE mode (system reaction)  This plc / system was installed 2 year ago and we've had this problem occasionally since. I'm guessing the wrong firmware was used during the install. Will try upgrading firmware this weekend.   
  13. Hello      I have a cj2m processor and md211 module and I want to read position from rotary encoders who are put on the stepper motors. I use high speed counters to count the number of(I made settings like in documentation) but every time I read velocity.   In first two picture I have 3 blocks for PRV function , I set port specifier [#0, #1 and #3] because on this ports I command 3 axis. Please help me!              
  14. BECKHOFF CX-9020

    Hello PLC experts, I am master student currently writing thesis. For this, I have a initial task of making some changes to PLC program (Just started getting to know about PLCs- complete beginner). I have a BECKHOFF cx 9020 PLC connected to my notebook using ethernet. I am using TWINCAT 3.1 (VS) as IDE. Firstly, I cannot find my PLC IP address connected to my notebook . I added the route in the Twincat and it shows the PLC is connected. When, I am trying to run a program (activate boot project), I am unable to login to the PLC. It gives an error "login failed for application port 851". What I undertood from BECKHOFF scripts,  there is something wrong with the ADS ams net ID which I am trying to figure it out. I appreciate all the help. Thank you.
  15. hallo everyone ...i use mitsubishi Q00UJCPU and QD77MS2.. i try to make a speed control program and the speed wants to be changed during servo operating, i use dedicated instructions ZP. PSTRT1 (axis 1) and have tryed but it was only successful to change speed with "change speed control" function once ... is it like it? cannot change "change speed control" many times when servo operations?

  18. High-Speed Counter Input

    Hi, I working on reading impulse from the input. I am using M8000 as a contact, on the coil [C235 K9999] and it is working fine on the lad, but the problem is I need to applicate sth like that in structure ladder but I dont know how. I found function on the image below but it is for FX3U. I know that 2-phase 2-count input use OUT_C(for example EN True| CCoil CC251| CValue K0) and then DMOV(for example EN True| s CN251| d D100), so is there any method to read impulses from the input? .Thanks in advance. PS I have Mitsubishi FX3G series.  
  19.  Hi all. I have a question about how to set up the motor in rotary mode. My application will be a basic rotary table driven by a servo motor without gearbox between. So, in my servo drive axis settings, I select the motor as a rotary mode. then I defined the maximum position setting value for 360 degrees, and minimum to 0. So far so good. But the problem comes when I want to make an absolute move using the mc_moveAbsolute to move 360 degrees. Whit this settings the error "target position settings out of range " will come up. So, what is the solution to rotate 360 degrees without generating this error? if I set up the maximum value to 361 degrees and then if I rotate 360 the error will not occur and the motor will rotate 360 degrees as I aspected, but it's this correct ? or there is another way to do it? Thanks  
  20. C-mode hostlink library for NJ/NX1P or CP1L

    Anyone knows if there is a C-mode hostlink library for NJ/NX ? Also, a C-mode hostlink library for CP1L could be helpful, to translate such a library to work with NX1P is probaly less work whan writing a new library.  Maybe Omron France has developed such a library? - they seem very active..   Background: Looking into writing a programmatic c-mode hostlink master for NX1P12, this is for connecting the handheld NSH5 HMI to the NX1P12 via RS232C using a CIF01. I have the hardware set up, and an machine built, expected some compatibility efforts by Omron.... but the NSH5 seems to talk C-mode hostlink, and the CIF01 only seems to support the FINS version hostlink.   On the NJ you can of course add an SCU module, thus not need a library.  But working with NX1 ( due to limited space available ), you are dependet on available CIF-modules which do not support C-mode hostlink.  
  21. Omron Servo Encoder

    Hello All  I am new to PLC programming , i have a question regarding omron PLC and High speed counters. I am using Cp1H-XA model plc . I connected HSC port 0 with a encoder and i was able to get the speed of the encoder using PRV2 instruction. Now i am trying to connect the second  encoder from the servo motor that i am using to HSC port 1. I am getting the PV signal using PRV instruction . Is there a way to calculate the speed of the servo encoder connected the HSC port 1 using PRV command , since i can't use the PRV2 command for the servo encoder .   Thanks in advance .
  22. Average motor speed

    Hi Guys!   There is a task. I have a motor, and I can monitoring the actual speed. The question is how can I to determine the average speed, if I know just the actual speed. If the speed is zero, it must be ignored. So I have to measure when the motor moves. Anybody have any idea? How can I solve this problem. RSLogix 5000.  Thank you.  
  23. Here is a link to a thread on a recent post showing how to communicate serially to an Omron PLC using VB.Net. This uses the Omron Host Link serial protocols. (C-Mode Commands) It will read 10 DM registers and display them on the form.   http://accautomation.ca/implementing-the-omron-host-link-protocol-vb-net/ Here is the source program that can be downloaded.

  24. Hi, I have some trouble with a CJ2M-CPU33. My client did a backup to memory card earlier today, and after this we did some changes through remote link. Now the client wanted to restore the previous backup to the PLC and has done so, but the system would not function correctly. After going online on the PLC it seems like the PLC is stuck in "Stop/Programming Mode". When trying to change to "Monitor" or "Run" mode a dialog comes up containing the following message: "Failed to change the operating mode. The operating mode may be still changing in the PLC."  - All the dip switches are set to off after restoring backup - The PLC has been rebooted  - I have downloaded the application again through CX-programmer  - Verified that the PLC is set to start up in "Monitor mode" But nothing helps. The same message comes up when trying to change the operating mode.  Hoping anyone can help to resolve this issue as it is very critical for us and the client. In advance, thanks for any tips or help received. Best regards Stian
