  1. Hi All, I have an AB servo TLY-A110T and 2097-V31PR0-LM Kinetix 350 drive. I thought that it was fully configured and ready for tuning, but when I issue a MSO it immediately starts to spin the shaft (no load yet). This lasts about a second until a Physical Axis Fault, Excessive Velocity Error occurs. I've double and triple checked the feedback and power wiring, and everything looks right. Is there anything else I can check? What can I do to trouble shoot this if I can't even give an MSO? Any insight is greatly appreciated.

  8. 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?
  9. Does anyone have an example piece of ladder logic, created on a Micrologix 1200, using ASCII to READ and Write to a serial device?  I am building a ladder on a Micrologix 1200 that will send data to an old CNC once a certain ASCII instruction is received on the PLC.  For example, when the machine spits out an ASCII "1", the PLC will see the "1" and send out a three digit number depending on a sequence of discrete inputs.   Thank you,
  10. Good Evening, wanted to introduce myself. I've been in the Electrical, Instrumentation and Controls field for 25 years. I'm looking for opportunities to build control panels, any info will help.
  11. Square Wave Problem With Micrologix

    Hello all, this is my first post. I am using an AB Micrologix 1400 (1766-L32BXB Ser C FW 21). I was trying to generate a pulse train using the PTO instruction. I have modified PTOX funct. file. The ladder is just a simple XIO followed by PTO, (The Quick Start ladder from 1766-RM001). When I looked at the output waveform on my oscilloscope, I noticed that it wasn't a square wave. I decided to run it at several different frequencies to see how the wave form would change. At 10Hz i got a square wave. As I increased the frequency the falling edge became sloped and almost horizontal. Is this how the output should behave? The data sheet indicates a max frequency of 100kHz, but at frequencies over 150 Hz. The wave form looks like the output of SMPS. 
  12. Is there a way to monitor the Temperature of a Servo Motor on Allen Bradley Servo motors... MPL? PLC: CompactLogix 1769-L30ERM Drive: Kinetix 6500   Motors: MPL-B310P-MJ72AA, and  MPL-B560F-MJ72AA I would like to be able to monitor the temperature, and flash a warning screen on the HMI if the Motor gets too hot, or perhaps shut down the operation before the Motor overload trips. The drive and PLC are connected through Ethernet IP What I don’t know is if that Motor heatsink temperature information is available to the PLC.
  13. Hello, I'm new to PLC Programming, with just a simple course about the basics. I've got a micrologix 1400 PLC which seems to have had its program wiped when the battery was replaced. I've had the company that supplied the machine it runs send me the program for the PLC. However, I don't have any software to communicate with it, and download the program to the PLC. I was hoping some one here could help me out and direct me towards what I will need to do to get the new program installed on the PLC. Thank you 
  14. Hello - I've recently started my adventure into PLC programming and I've found this site to be very helpful. I took on a project that requires control of a cylinder - the short and skinny is that the cylinder will have to provide position feedback and stroke to various set lengths determined by position of a selector switch. So - If position 1 is selected, the cylinder will stroke 20"inches. If Position 2 is selected, cylinder will stroke to 25"inches - so on and so on.   My questions is how to best go about this process. I may be having a brain-block and not viewing this clearly, but something is not clicking for me and wanted some advice. Planned on using Allen-Bradley's Micro850 PLC (had one on the shelf, and CCW software is free so why not). Thanks
  15. Hello I have a scenario that's been bugging me for some time now. The scenario consists of a Micrologix 1400 that I need to control it's output from modbus/tcp. In detail what I really need is to be able to manipulate the O0:0 through modbus/tcp. The PLC would be the master and I would be the slave that triggers the connection to the master. I'm using a Modbus-Client on my PC and that should be the slave. Any idea as to how I can manage that? Currently I can send data to the master but everything is "stored" on B10 and I have no idea how I could write directly on O0. Thanks a bunch guys. PS: I'm borderline noob. 
  16. Dear Friends, I am doing a pick and place project using stepper motor.programmed movement by PLS2 command and motion are running fine.I want to program origin for the stepper axis.Please help. i don't know how to origin with a home sensor input.I am using CP1E PLC and stepper driver DM860.
  17. GX Works 3 - PID control

    Hi, I am using PID function (PID operation instruction) from GX Works 3 library but it doesn't work. I set all necessary parameters (sampling time, direction and upper/lower limit values + KP, TI). My input PID_Par is array of 25 points (in manual is written: "*1When auto tuning is not used, the same number of points are occupied as when the step response method is used."). For example, in GX Works 2, PID function works ok. Did someone have similar problem? Does someone have mitsubishi library (GW Works 3) with PID function that works correctly?   Regards Luka  
  18.  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  
  19. Hi my problem may have a simple solution but i cant work it out. I need to use the Divide function but it wont let me use a decimal point in either Source A or Source B. Is there a way to use a decimal point in Logix 500 Math instructions? Im using an AB Micrologix 1400 PLC. Can you only use math instructions with whole numbers? is there a way around this? Thanks James

  21. 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.

  24. There have been many good discussions on the applicability of cloud-based solutions for manufacturing and process control systems. On one side, some people have concerns regarding security and control of the information, on the other side, there are identified benefits enabled by cloud systems. From VMS minicomputers to DOS and Windows, from ArcNet to Ethernet, it is inevitable the industrial automation systems shall adopt the technologies that are getting predominant in IT general use; the current environment that I am calling the “Cloud-iPad era” is no different; therefore the practical discussion is not if those new technologies will be applied in the industrial environment, but how. This paper is not intended to join the conceptual discussion about the cloud, but just to present a few simple practical examples, where cloud technologies are already enhancing industrial automation solutions and enabling new business opportunities.
