  1. I've had some problems getting the Junma ML-II drives to work all the way as I want them to with the Trajexia controller. One issue has been the homing sequence. First the manual enclosed with the drives erroneously lists /DEC to be on pin 1 at CN1, and /EXT1 on pin 2. It's the other way around. Second, it turns out that the Trajexia, unlike the MP2300 I've used before, does not use the ZRET command in the drive for homing. Instead, it performs its own homing sequence, thus using /DEC (which has no particular meaning to the Trajexia) as the homing input instead of the /EXT1. For this to work DATUM_IN AXIS(x)=26 must be given prior to using the DATUM(3) command, for example. By reading the normal Trajexia manual, one gets the impression it must be something in the range 28..31. Another issue is registration. /EXT1 is used for registration only, where it turns out that in spite of the SJDE drives not supporting windowing for the registration input, this is supported anyway, by the Trajexia. But this implies that all registrations are done by the drive, the Trajexia validates them and re-arms the latch input if it turns out that the registration input came outside the window. A process that takes about 3 ms, with 1 ms servo loop time, since values has to be communicated back and forth for this process. Not until the Trajexia has found that the latch was taken inside the window, does MARK go true and REG_POS is loaded with the latched position.

    Traditional PLC programs are always different in systems programmed like the Trajexia. We make enough machines to have our own general controller, programmed in C, where you face the same problem. With suitable library routines written, it works pretty well. To begin with, we intend to use the Trajexia together with our system. Perhaps time to start a specific Trajexia thread in this forum. I'm currently testing a system with 6+3 axes.
  3. Advantage / Disadvantage

    I tried to follow this thread, but it seems a lot of questions are missing? Anyway, Medoc has been rewritten as a Windows 32-bit console application, so it's now really a windows application, but still with the DOS appearance. One big advantage of GX developer is that you can have the name database open simultaneously with the program.

    I already have a contact in Barcelona, so that's no problem. You didn't comment upon the question about if you have used it for something? I'm in the evaluation phase right now.

    Yes, Trajexia is a product of Omron Europe. A lot of the work has been done by Omron's MAC center in Barcelona, Spain. Is there any genuine Omron multi-axis motion controller for Mechatrolink, really? There are these originating from Yaskawa, the MP2XXX series. I've worked with the MP2300 a bit, but it's much different compared to the Trajexia. It's true that Trajexia tools comes with v2 only. You aren't supposed to be able to run it under v1, but it worked anyway, with some tricks. Now I've got the correct version I should have had from the beginning, so now it's no problem. Anyone here using the Trajexia?

    I ordered CX-One, but due to a mistake at Omron, I got version 1.0, not version 2.0, as it should have been. Now there was no Trajexia tools inside, which was what I should have used it for. That can be updated from the web, but now it seems I need to clean away version 1 first, before installing version 2, when it arrives. After two days of use I've found two errors in the Trajexia manuals. Not too good for the future.
