  1. 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  
  2. Hi there I am working on a project where Omron servo drags a part to a certain position using belt mechanism, But to avoid any slippage we decided to put an external encoder directly on the part. I was wondering what is the best to approach to drive the servo using the position of this external encoder. Is there any way that it can be configured directly with the servo? I am fairly new to coordinated motions, any help will be appreciated. Thanks
  3. Alternative Servo Drives

    I'm sure many of you are in the same boat with supply issues and elongating lead times with the Logix 5500 and 5700 servo drives. Are there any decent alternatives that are easily integrated into a 5380 controlled system, maybe with an AOI? I've looked at Beckoff and Parker systems, but Parker only seem to line CoDeSys as far as I can tell. Do any of you clever clogs have any suggestions for a well stocked alternative? As a side note, I'm not new to PLC programming, but I am only 6 months in to using motion and servo systems so be kind :)
  4. Hello people! I'm using a NX1P2 controller combined with a CIF105 serial card installed on it. For my project, I get some data that are in ASCII form and I want to keep that form when are extracted in a .csv file. I have established the communication for getting the data but, the problem is that I cannot extract the data in the ASCII form. Data extraction comes in Hex form. I use the NX_SerialRcv instruction for the communication and the AryToString conversion for the data. When using the Watch Tab Page I can display the data in ASCII form but, as far as I understand, this is only for online monitoring. I went through topics here and OMRON manuals for finding any Hex to ASCII conversion instruction but the only info I came across was for CX controllers which cannot be implemented to NX controller. Is there any similar instruction for NX controller or I should create a new Library for the conversion? Any tips and/or a sample would be highly appreciated! Thanks! Man31    
  5. How do I communicate between an Omron NX1P2 Automation Controller and Indusoft Web Studio. This is the first time using an Automation Controller. I am familiar with communicating between Omron PLC's and Indusoft using OMETH drivers. What driver should I use?
  6. Hello! I'm trying to connect my QD75M2 with a MR-J2S40B1 Servo amplifier with an SSCNET cable. The problem is when I try to turn on the Servo ON/OFF on the Intelligent function in GxWorks2, an error occurs saying the servo amplifier is disconnected with my QD75M2. I'm confident that I've wired it properly. What could be the problem? Hoping you might help. Thank you.
  7. Dear All. I have the issued with NX1P2 when read data from Modbus RTU. the Slave data using 2 INT for Real data. but in the Sysmac Studio I get the data is OK, 2 INT but can not convert to Real data. Can you pls help me to solve this issued. also I want to convert from Real to 2 INT to send the setting to salve. Many thanks.
  8. Hello, Has anyone got an Omron PLC NX1P2-1140DT1 running with Modbus TCP/IP? I tried to reach Schneider several times, but there is "live" or email to discuss or get help, has to go to thru someone from Mexico then he will email to France. All of my attempts was lost, I can establish a "CONNECTION" but I can't READ the Coil - I got the error "Gateway Path Unavailable" (that means  "Used alongside gateways. Basically, this code means the gateway couldn’t allocate an internal path to process the request. Therefore, the gateway could probably be misconfigured or overloaded") My program is based on the MTCP_Client_NJ_E (Revision 2.3 date 23/07/2021 - JP Viskovic from France) I can read the coils using MODBUX Doctor (France) but I can't make work with Etherway. Any advice is welcome. Thanks   MTCP_Client_NJ.slr MTCP_Client_NJ_E.pdf
  9. Is it possible to reset " Motor replacement detected error" ( Error code 95.01) using code without connecting to PLC through sysmac studio? If yes please suggest how to do it... Thanks in advance...
  10. All of the ethercat servos I have installed are Omron. I have used many many brands in the past - over analog, pulse train, but not ethercat. I have one of the Yaskawa servopacks that can control two servos independently. The drive is all wired (POT, NOT, safety), autotuned, it's in RUN OK state, I have installed the ESI file, set up the axis, mapped the PDOs.. it's all working, but they do not move. I made a test program just with MC_POWER and MC_MOVEJOG/MC_MOVERELATIVE/MC_MOVEABSOLUTE along with the resetting of MC and EC and the servos do turn on, but ignore any movement command. They do not flare up with an error, and they give me their actual position, so the network is working. If I send the movement command the command position starts to differ, so the plc is/should be sending the command. I feel like there's something missing in the PDO mapping screen, but I didn't need to do all of this with Omron so I have no idea. I thought at first the servos needed huge units of movement and speed but the actual position value confirms this is not the case since it doesn't ever change.
  11.  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 ?.
  12. 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 ?  
  13. We currently have Delta DVP60ES2 and DVP32ES3 PLC's doing positioning control on Inovance IS 620PS2R8I 400w Servo Drives by Pulse/Direction. Under both of these environments our pulse count read on the Inovance drives are reading higher than what the PLC is outputting. We also have Mitsubishi & Inovance PLCs, which when connected to the same Inovance drives dont have any discrepancies in the pulse count. We also have Delta ASDA servo drives, which when connected to the Delta DVP PLC's also don't have any discrepancies. Given we have tested these combinations, it has led us to believe there is something unique about the pulse train output from the DVP PLC's that is causing the Inovance drives to read additional pulses. Has anyone experinced a similar issue with Delta PLC pulse output? If so what was the solution? 
  14. 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!  
  15. Hi guys, this is my first topic on this forum. I need an help with modbus communication through NX1P2+CIF12 and slaves inverter. I have never used this board, so i need an example to understand. Thanks
  16. Kinetix 6000 drive Gurad

    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.
  17. Kinetix 6000

    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. 
  18. servo auto tuning

    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. 
  19. Servo safety

    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. 
  20. 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    
  21. Kinetix 6000 Overspeed Faults

    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  
  22. 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.
  23. ROTARY AXIS POSITION ERROR

    Our C axis which is a rotary axis doesn't perform commanded postion, for eg if we give command of 360 deg, then it will only rotate 359 deg and for next time it will rotate 358 and so on for every rotation. i.e for every rotation its complete degree is reduced by 1 deg.  And system doesnt show any error.  By providing command of 360 deg, if we rotate or axis for 15 times then the last position at which it will stop will he 345 deg.    Please share valuable inputs to resolve that problem.
  24. Hello out there   I've searched for quite some time but unable to find any information helping me through this. I got a Omron PLC NX1P2 where im supposed to setup modbus communication over TCP/IP but so far i've only been able to find information regarding RTU setup. But seen forums mention its possible to setup via TCP/IP Anybody who can help. A program sample would be helpfull aswell. Im a trainee as automationengineer and this is my first encounter with Omron PLC and Modbus so quite new to the field.   kind regards Ivan T.
  25. I am currently trying to connect my OMRON NX1P2 1040DT1 (Using CIF-105) to my Unitronics V570 PLC, With my OMRON PLC as Master. It seems as if Unitonics Rs485 only wants a six-wire connection type but my OMRON PLC wants a 2-wire or 4-wire connection, Wondering if anyone has a solution to my problem and can assist me.
