  1. Analog input melsoft (fx3u)

    Hello, I am new to the programming of logic controllers. I have a Chinese FX3U 24 inputs and outputs with analog in and outputs. I am trying to teach myself the basics of the programming but I am stuck at the analog part.    what I am looking to do is create a program so that when a 12v battery bank voltage drops and rises it can trigger other outputs. I have a voltage divider which outputs 1/5 of the input.    Thanks for your help in advance.  Ben. 
  2. 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!

  4. GT2107-WTSD not showing in GT Designer3

    Hi guys, im just looking for some help if possible, I am trying to setup a HMI (2107-wtsd) but GT Designer3 does not have this model nor does it have any 2107 models in the GOT type dropdown. How can i get my model to show? I have tried setting the GOT type as a G2105 and the GT softGOT2000 and these did not work, the HMI is on a white screen with install package data but i cannot do this if it is not in the GOT dropdown correct? I have attached some pictures to show. the HMI is connected to the PLC via ethernet and the laptop is connected to the HMI via usb I am very new to this so we are using test benches so if anything looks wrong i am very sorry

  8. FX2N HELP!!!

    Hi!! i was wondering if you could help.  I'm currently working on my final year's project, in which i have to recreate a backup file of a LADDER program so i can transfer it later after i add the EEPROM extension.  if i transfer from my computer to the FX2N-32MR the ladder program, does it get saved in the EEPROM or RAM? 
  9. Hi, I have the following configuration where 4 PLC panels, with each having a Q12PH CPU and QJ71E71-100 module. All these QJ71E71-100 are connected to a HUB using straight cable. From the HUB one connection is going to an I-Fix SCADA which is already communicating with all 4 PLCs using MC protocol. I want to send data from 3 of this PLCs to the 4th PLC in the same network using fixed buffer communication. Can anyone provide a sample program for the same. Send and Receive side. I am using GX Works 2 for programming. Your help is very much appreciated.
  10. Hi,  Can someon help me with the following question. Like what makes a Kinetix 6000 drive a Guarded drive ? What type of safety stuff can you set to make it more safe.  Is it some parameter ? I am bit confused, by the manual. Should I active it in the PLC program or how ? Or it is some setting like a safe speed or torque.  I would really appreciate any help. Thank you so much ahead.  Have a great day, thanks for the reading.
  11. Hello guys!  Im using RS Logix 5000.  Can someone explain me what is the difference between when a servo is shutdown or disabled ?  I read the help but it says the same. I can assume it like when its shutdown, there is inside some circuit which is not allow the 3 phase for the drive.  Disabled is that when it have the 3 phase but nothing can happen ? Is there any difference with the break ? Like when its shutdown it can rotate until its slow down by itself or the break will be active ?  I tried to uplod a pic but it was not succesful. When you open a servo axis properties and you choose the Fault actions tab. You can find there these settings.    Thanks a lot. 
  12. Hello Guys! I have couple of questions about tuning an ab servo motor. -Actually what does the drive or plc doing when I launch a servo auto tuning?  - What are the little boxes like position error integrator ? There are checkmarks in fornt of the lines. Can I choose the methode or something? I mean its not "auto" ? Why it is auto then ? - Can someone send me some basic literature where they explain me what these stuff acutally meaning ?  - What is the hook up test what for is good ?  -When you are doing a servo auto tune what are the parameters that you are monitoring and why ?  -I should do the auto without or with load ? Whats the difference ? I know there are so many question I would be so grateful if someone could help me with these answears, or even just with one. Thanks again. 
  13. Hi. I would like to ask that like you guys are when using a kinetix servo motor what type of safety conditions are possible ? I found a fault actions label. Is there anything else like between the parameters or so ? Thanks ahead.

  17. Hi Experts, I would like to know is there any possibility to make a switch that can make exponential increment to a data. i know how to make a switch to increment data in fixed intervals with a switch but im trying to make a switch when you press it continuesly it should increase the gains rapidly over time. is this possible and if yes can someone explain me how? im attaching a sample image how i want to make two buttons to increase and decrease a data. thank you in advance guys. kind regards, sathu.
  18. Good morning guys,  in your experience what is the best way to syncrhonize a motor controlled in speed with an inverter and a motor controlled in position with a servo drive? Let me explaine better what is my situation: I have a belt running normally at a certain constant speed. in some moments, I would like to syncrhonize the speed according to an axis controlled from a servo. the command of a servo specific position target and of course speed and acceleration e deceleration rate. I would like to adjust the belt speed in way to follow as accurately as possible the servo movement. Thanks a lot Andrea

  20. FX-2NC-32MT PLC Error

    Hi, My PLC is showing error. I removed all the input & output cable from the module. Still the error is there. Can anyone help me please. What is the issue here?   Regards Sohel Ahmed
  21. Anyone possibly have software for the Mitsubishi Positioning module AD71 (SW0IX-AD71PE) ? It's a servo positioning module for A Series PLCs that can either be programmed by an old programming terminal or a DOS based program for PC. I think SW1IVD-AD71P could also workReally hoping to find the any compatible software for this controller. Maybe someone has leads?
  22. Hi all, I'm having an issue with one of the Kinetix6000 allen bradley servo drives on a filling line that I support. This particular servo motors controls the rotary movements of a series of pumps to ensure accurate dose timing. Every time that I start up the machine, the PLC (Controllogix L7 firmware v28) executes a homing sequence to ensure the servo finds its 0 point. However, the servo in question keeps getting an 'Overspeed Fault' (E55). So far in troubleshooting, we've basically changed every component. We replaced the drive, feedback cable to the drive, and even hooked up a new free-spinning motor directly to the drive. Every component change has resulted in the same Overspeed error shortly after the homing sequence starts. To try and rule out a mechanical issue, I even disabled the homing sequence in the PLC and tried to move the motor using Motion Direct Commands. Immediately after a MSO command, the drive faults out for OverSpeed even with no motion. The last bit of troubleshooting we swapped the position of two of the drives, but the same OverSpeed fault happened on the drive connected to the rotary movement motor. At this point, I'm even considering changing the sercos fibers and the Kinetix power rack. Has anyone experienced anything like this before, or have advice on what to try to make it work? Thanks in advance for all your help  
  23. Hi guys, Has anyone ever implemented a Siemens S7 RFID tag reader into a Mitsubishi PLC system? Is this something that is fairly supported to be able to achieve? Or a right pain to set up?
  24. 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.
  25. Hi guys, im trying to redirect a screen when a bit is active in GT designer3. im still a beginner in the GOT. any help? regards, sathu.
