Hi people OG58 here (old guy 58 years) I am looking for some suggestions for my training project that involves controlling a 3 axis CNC machine (router table) using a Q02HCPU with a QD75MH4 to control the three axes. I am thinking an analog card to control the spindle speed would also be a nice addition., Any thoughts or suggestions would be greatly appreciated.

M codes are just machine functions like M03 Spindle forward, M05 Spindle reverse and S2000 = 2000 RPM. There are quite a few of them for coolant and vacuum etc etc. Thanks for the software os reference number. The Q172DCPU has a fibre optic interface that I am keen to use. If anyone knows the cat number for the cable I would appreciate that as I have not found it in the manuals yet. Already the specs are dictating to use a JR3-B type servo amplifier. I have a home built CNC machine that I want to rebuild into a stand alone high accuracy real time system. Also post processors are just software to calculate optimum tool paths to the machine from cam software some are good some are not so good. Edit: The fiber optic SSCIII net cables cat number is MR-J3BUS05M ( half metre long).

I read manuals until I know them.

I have a Q172DCPU on it way to me now. I believe I can interface this with my current setup. I will use the Mitsubishi MR-J2 B or MR-J3 B type drives and 100 watt AC Servos also Mitsubishi K13's. The Q173NCCPU is that the one in Mazaks? The best machines have 1 micron resolution I only need 10 micron. Yes I should have realized the CNC servo motors would be application specific. I have some dual shaft nema 23 motors and 100ppr encoders 2phase. I am considering stepper motor first now. Thank you

Hello People, (first post newbie here) I purchased a secondhand FX2n48MT and I have cleared the memory and the error light appears to be latched on in a special latch and register. I can read and write programs to and from the plc and the plc is running the programs. Any ideas on how to clear the error?

Thanks for your input Wasan. I checked it out looks ok but I want to build a Mitsubishi based system. I have a few cpu to choose from and many peripherals, enough to build a full CNC system. Cheers

Thank you glavanov 1. I definitely need G-code support. Can you suggest what hardware I might need in Q or A series PLC? 2. 3 axes helical interpolation is also an absolute necessity. 3. I need up to 10,000 lines per program with full HMI The Yurtaev Linux card looks good it can run with MR-J2B servo drives. The Q172DCP is built for SSC net should I use this motion controller cpu instead? Cheers

Yes thank you I now understand the QD75MH4 is more suitable for low control system such as repetitive servos on conveyors etc. I will try it out and let you know how I go. Regarding what I want to do is build a plc/motion controlled CNC 3 axis machine that can read G-code and perform in real time. Servo options are DC stepper type with closed loop control or Mitsubishi MR-J2B type AC servos with power in the 100 to 200 watt range. The projected work area is 600mm x 800mm

I am using GX developer Inntele. My personal thoughts are ROM bios image parameters changed or corrupted like memory error. I just wanted stepper motor control. So now I must go down the A or Q series path.
-
I am giving up on the FX2N-48MT and accept it is faulty and will now concentrate on Mitsubishi A and Q series PLC. Thanks for all your input I learned some new stuff cheers.

I agree 100%, time is precious don't waste it.

Thanks I have the same problem with a small 7" HMI KINCO screen.

By this post I am in tears.

Great work with the diagram. I have many cables with 6 and 8 pin mini din type connectors and I suggest to people that they should label their cables. This will save frustration when you have identical looking cables that are wired differently.
-
Thanks for the POST Paolo_911 I have this card and your post gives me some good info to set it up...Cheers

Personally I rate Mitsubishi PLC's very highly for a number of reasons. PDF format manuals are readily available for download online for free. Modules and components are easily obtained both new and second hand at reasonable prices. Mitsubishi PLC's are very reliable and also very easy to expand to suit almost every situation. They are very easy to learn and program. There are many online tutorials and examples. The above comments refer to AnS series, Q series and Fx series Mitsubishi PLC's as these are what work with.

First in First works. If Y0-Y7 are on then Y10 or Y20 will not activate. Y0-Y7 stays on.

Hi Kaare_t, quote "So if I understand you correctly, you can switch on 0-7 OR 10-17 OR 20-27, but not several "batches" at once? " Yes that is correct.
-
Hi Inntele, Thanks for your input, I checked those m contacts all zero and all registers read normal. I guess I will eventually find out the cause. Reference Mitsubishi manual JY992D66301H aka FX2 hardware manual.

Yes the unit may be faulty but apart from the output problem it works fine. Ok I have been reading the manual and going through M points and D registers and can still find no indication of error. However the physical manifestation appeared last night and here is what happens. I attempt to use logic to switch outputs on and everything is fine until I try to exceed Y7. I can switch outputs Y10 to Y17 or Y20 to Y27 but only any given 8 outputs at one time. Do you know the correct parameter settings for this model? This is not my first time with a PLC I have a few of them and wrote my first PLC program in 1986 (Instruction code).

maybe the correct peripherals too.

Thank you Ron_S Yes I have done that and the PLC says no errors? I am using GX Developer ver 8 something. I have looked through several manuals and tried resetting M9011 all to no avail.
