Pule train (step/dir)?

What signals are you using from PLC to control the stepper? 

Sound's like you need STL (step relay or step ladder some may call it...). In the IQ-F manuals, as i recall, there's a common overview of STL instruction. More details yo can find in Fx3 series programming manual and it work's the same way And the only difference was, that with FX3's STL end's with RET instruction. With IQ-F end's with RETSTL. But this is for ladder project.

Dear All, Anyone experienced with RV-F series 6 axis vertical robot? I Have an upcoming project with RV-70F-D palletizer. I hve overwieued Melfa  basic V "Def plt" function and i fully understand it, but this is oly for the first layer on the pallet. What is the right way, to keep overlaying  products on top of each layer...? Should i keep "def plt 2, 3, 4 and so on for evry new layer and just "def pos" the points from layer 1, but with height of the product added in .Z of points of evry new layer. Or maybe there's more eficient way?

Work's like charm! Gambit, thank you again!

Sound's pretty efficient to me!  I just need to modify Place.Z=Place.Z+(product height) for the next layer. Or maybe Place.Z=Place.Z+(layer number*product height) I'll give it a try both ways... seems like it's up to imagination... Thank you Gambit. A good example, pushing the right variable, not all of it. 

Thumbs up for RS-485. IVMC is very useful function!

Oh, here we go!  And restart GX W3 after adding the profile. Then you see the module in the list. Thank you Clear.Mind. Let the force be with you!  Tuning complete.

No, i'm just tuning my knowledge...  i only have the cfg tool. The ENET/IP manual says, that the module should be in the list! No luck with Gen. Intelli module... If someone can't find the tool: https://eu3a.mitsubishielectric.com/fa/en/service/download/sendfile?form_submit_orig=Download+now+with+the+standard+filename&id=13232&sendName=FX5ENET-IP+Configuration+Tool+1.00.zip&useOrgName=true&orgName=FX5ENET-IP+Configuration+Tool+1.00.zip&doc_type=doc_loc&part_1=0&fileNameCreated=FX5ENET-IP+Configuration+Tool+1.00.zip&fileNameManual=

I'll give it a try...

I have GX Works3 1.52E Why i see only the ENET, but no ENET/IP module in the information module list?

Can you post your program here? Are you trying to preform speed control? What is your application? Why are you using exactly PLSY ?

Axxaxaxa... you manage to spin 3,5kW (17Nm) servo with 100W amp?! Now, that's the spirit... Мать моя женщина!

Man, are you sleeping with servos under the pillow?!  That's very useful info. I have one spare JE20B and can test it with HF-KN13 (100W). Ill give it a try for the sport and  the science... resolution i s the same, but different capacity  

Yurtaev, класний ти пацан! This actually might work, but i don't have the hardware to test for the moment... Where is Pr.PH18? It's not in the Pr. list of MRC2 in any mode... maybe it appears only in J3 compatible mode after write PA01 - 0000 and PA19 - 00AB and cycle power? With ModeChange tool, also...    

Positioning data-->1 Axis speed control-->speed value= [(pulses/rev*100)/60sec.= sulses per second(rpm)] This is for pulse units system. As i recall, electronic gear can be used only in synchronous control settings...  Caution for Pr.21 in module parameter settings!

Who RST M502? Your MOVP instruction will not work again with M502 on

Did you turn off/reset speed change request signal after completion of that function?

No chance! Motor series(HG-KR/MR for J4 and HF-MP/KP for J3) and resolution are different, not to mention, that you can't run 100W servo with 200W amp. 

Arrange the topology of you cabinet first, and then chose optics length. I had some troubles with 50cm optics (from motion CPU to first amplifier) when trying to leave space, so the controller and amplifiers can ventilate... you should not bend the cable too much. For the M codes, i meant that those (M03, M04, M05 and S value) are not in the list of supported M codes in the G-code program for this motion CPU. I can't find post processor for this CPU. You may have to write programs by hand. Check the programming manual for SV43. It's for Q172HCPU, but again... http://meltrade.hu/download.php?f=4186-q172hq173hcpu-programming-manual-(sv43-g-code)-ib(na)-0300115-a-(02.06)

Oh, now i see. Q172DCPU supports g-code motion program (up to 8 Axis) with OS type SW7-SV43QC. If this is your case, actually might work... What's the deal with spindle control M03, M05 and S(speed)... and post processor?!  

The only Q series cpu that covers your requirements is Q173NCCPU. It's a part of C70  CNC control system that operates only with NC servo drives. No support for general purpose melservos. Someone correct me if i'm wrong. If you consider alternative with  closed loop steppers, maybe the best solution on the market is ClearPath SDSK servos. Right now i am retrofitting one multicam router with thoes, using CSLabs Csmio controller.  

This positioning controller is not dedicated for CNC controls. 1.No G-code support. 2.No 3 axis helical interpolation, only 2 axis circular. 3. Positioning data limited to 600 lines per axis and shared when interpolating... 4. Flash memory limited to 100000 writes. Same number for the main CPU. If the machine work with just a few simple positioning tasks that repeats it self, than it's fine, but it's a bad call for a common CNC router that runs with many different programs. Since you are stuck with SSCNETIII servo network, your only alternative is a SSCNET  3rd party CNC controller PC card like: http://www.yurtaev.com/ But again, too much lack of info for go/no go, as CrossBow said...  

when the unit system is mm (microns) 100.0 microns is written as 1000 (32bit integer) int the buffer memory. All positioning data saved in the flash memory of the motion controller can be manipulated in the buffer memory and you can change it with sequence program from the main CPU. If i'm not wrong, the only condition is to change the data(positioning address) right before positioning start signal activation. In another words, this can work for you, if the variable stop points are defined before start of positioning. If you need to change the positioning address during movement, there should be FB for target value change. Does the liner movement stops during cutting process or it's a kind of flying shear? How and when are defined the cutting points?

Just use  [D<= Kn Dn] and interlock the instruction till next time you need it... STL is one of the good ways. Tested it my self and works like charm. Can still get one scan delay. You can use poin table in continuous path control and output M codes or just monitor the positioning data number being executed and compare the value to start external function. But still it depends on the type of application and axis control method.
