  1. Kinetix 6500

    Hello All, I'm completely new to the motion control systems and I'm interested in learning servo programming and motion control. I was trying to find a good resource that I can start learning from A-Z, but I couldn't find any. I have a demo kit with compactlogix processor and two kinetix 6500 drives with servo motors. What is the best way to learn it. If you guys have any resources or basic sample program please help me. Any learning material would be helpful. Thank You All
  2. Error on Mitsubishi Servo Pak

    I have a Mitsubishi servo Pak #MR-J3-40B with an error 25 and 95 flashing. Could not find any help on the web or in the manual. Any help appreciated.
  3. Position Controller

    hi, im student im trying to make a position control with the misubishi serie of servos, i have 2 mr-j2s-20a and 1 fx2n-20gm i was reading the manual i didnt readed all yet, i wat to know if i can control the position with a fx2n plc and if someone can send me a example of a code using it. thx for your attention 
  4. Beginners Servo Help Required.

    I have been programming Omron plc's for a while but have not used any servo drives. I have customer who is free issuing the following equipment for a project he wants programmed.: cj1m cpu21, r88d-gt04h, r88d-gt08h, r88m-g40030h, r88m-g7503h-s2. The small drive is connected to a simple ball screw moving a stop. The second drive is connected through a gear box and chain drive full details not known to date.  I have read the cj1 manuals and will be generally using  pls2 commands for the position movements.  Are the drives plug and play? If I connect the drives leaving the parameters as out of the box defaults should the drives operate using the pls2 command. In this condition I assume it is 10000 pulses per rev of motor. I can scale positions with maths in Plc and send the required pulses. Any guidance appreciated to confirm I am on the write track. I assume I could also use the electronic gearing parameters. Any examples using 5mm ball screw!    
  5. Servo gearing

    should be an easy question.......have a machine with several AB Kinetix 350 problem gearing them together or gearing them to an Ether/IP encoder. can't seem to find any method to gear them to a local io encoder channel. any suggestions? thanks, bob
  6. Hello Dears, I am studying to control position via Mitsubishi device Now, I have Q172 CPUN and MR-J2M(MelServo) to control position. But, I didn't find manual that explain command and parameter to do it and it has the example to do it. who have experience to control position, pls help me to overview it. Thanks so much!
  7. Hi... i want to ask about QD75D4, how to change rotation direction in positiont data ? If position data number 1 is CCW and position data number 2 is CW.   I try give value 100 (hope run CCW) and -100 (hope run CW) on posiition length but not respond.   Parameter axis #1 Control system = 2:INC linear axis   Any setting mistakes ?   Thank you
  8. Kinetix 5500 with Mpl motors

    Hi everyone. I am after some feedback from anyone who has used the Kinetix 5500 drives with Mpl motors on a motion project containing up to 12-18 axis. How reliable have they been? What logix firmware did you end up with?  I have used both the Kinetix 6000/6500/300 drives in the past but would like another opinion before I attempt to promote this product to my customer. Thanks 
  9. Please suggest me about these issues: Issue: No Rotation 1.     The motor links are slack or release. 2.     Distant issue is stuck in the glide. 3.     The motor load is extreme. 4.     The bearing are shabby. Issue: Overheating 1.     The rotor is in part demagnetizing cause extreme motor present. 2.     Motor voltage is exceeding the highest value. 3.     The duty cycle is extreme.  
  10. Motion Axis Gearing (MAG)

    Has anyone had any experience with motion axis gearing on Kinetix 5500 Drive with VPL servo motor. I have a project with a 5370 L33 ERS compact logix controller, one of the items we are doing is tapping a drilled hole. I have set it up to do an approach with one servo with a MAM command then MAG the other servo as the master. It is to tap, MAS, then return, un-link and go home. When I tap the hole it will tap about six holes flawlessly then on the seventh hole it starts its tap and when it stops to reverse it faults the axis when the axis goes to reverse after MAS. The fault that I receive is Feedback past factory limit. I also found that every time this happens I find 6 data packets lost. Any ideas would be helpful. Thanks
  11. Is it possible to read (and maybe write) the software limit values of a G5 servo from NJ code? It appears that PDO entry 607D would allow this, but how can I read/write to it? I don't seem able to map that entry to I/O. Thanks.
  12. Looking for a servo user manual.

    I'm looking for a user manual for the R88D-KN50F-ECT-L 5kW linear servo motor drive with EtherCAT. I have found Omron manual I577-E1-02, but this seems to only cover drives up to 3kW (R88D-KN30F-ECT_L.) It may be that there are no huge differences between a 3kW and a 5kW model, but I would like to have a manual that covers it if possible. Is there a more up to date version somewhere? Thanks.
  13. I have an application using Kinetix 6500 servos and Compactlogix PLC. The app requires a change to the MasterPositionFilterBandwidth(MPFB) at particular times during gearing motion depending on the circumstances. This value can be changed instantly using an SSV instruction but I have found the new MPFB value does not take effect until the Axis is stopped or turned off. Once either of these has occurred, the new MPFB value becomes active on the next gearing motion instruction. Can anyone help me with how I can make this MPFB value take effect immediately?
  14. I have a 2 axis control that runs a pair of identical servo drives. as of late I have been getting reports from the operators that the two motors, while jogging forward will suddenly run in the reverse direction at a high rate of speed. There is not a reversing function on these axes in an way. I am suspecting there may be a problem in the analog output of the module causing an inversion of the signal which in turn causes the motors to run in reverse. This setup has been in operation without any instance of this happening for around 5yrs before any issue with out of control runs. All cabling has been checked and is properly shielded and grounded.
  15. Small Wire Winder Project

    I have a project I am starting and I have to be able to wind a small diameter wire onto a 1/16" shaft, .5 to 1.5" wide and 13 layers at a max speed of 2,000 rpm. Is there anyone who has done something like this and have some sample code? I am gearing 2 Kinetix 350 drives with 2 AB servos.I have a separate tension unit that I have to communicate via RS485. Not to concerned about that. As the coil winds the traverse will move the wire back and forth.
  16. Dear experts, I have been trying to flash parameter to QD75MH1 module from PLC. Every time I monitor the servo via GX-configurator QP, I find 0 error, 0 warning but in the history tab it shows "start not possible(108)". But when I did it by flashing the parameter by GX-Configurator QP(Specially invalidating forced stop option" it works fine and servo motor jogs. can anyone help me to write the forced stop value from PLC program?
