Hi
I have motors and drivers Mitsubishi ... but i am need a help ...how i can connect this drivers to mach3 ... can you propose me some controllers non very expensive to tray this ...
Thinks

If they accept step/dir (pulse/sign) then you have many options from the parallel port to smoothstepper to CSMIO, Galil, Kflop etc etc.
If they only accept Analogue input (+/- 10v) then there are a few controllers such as CSMIO/IP-A, DSPMC, Kflop/Kanalog

My drivers is MR-J2S-60A .... i think hi can do step/dir
https://my.mitsubishi-automation.com/downloads/view/doc_loc/1375/138918.pdf?id=1375&saveAs=0&form_submit=View+now
if you can see page 24 hi can do with parameter 0011 .... i never set this parameters ... can you help me ... or if you have a filet set it directly by PC will be good ..
Thinks

sorry I dont have the software :(
Hood

Hi
can you confirme me if J2S-60A can do step/dir
thinks
-
Yes, as you pointed out page 3-24 shows the parameter to set for it.
Hood
-
and if i go with CSMIO ... witch one i can choose ... he have many models ... the CNC have 2 motors for axis X (one each side of CNC) 1 motor for axiz X and 1 for axis Z .
-
The IP-M or IP-S would work for you. The IP-M however is limited to 125KHz pulse so you may possibly have to use electronic gearing in the drive, that will depend on the steps per unit and velocity you had. The IP-S can pulse to 4MHz, so no electronic gearing would be required.
There are other controllers such as the Ethernet SmoothStepper (ESS) that can pulse to 4MHz as well but the ESS is only 5v I/O and also just single ended Step/Dir signals. You could possibly use single ended signals with your drives but they may be unreliable unless you are very particular about shielding. You ideally also want a breakout board if using the ESS, the CSMIO controllers dont require breakout boards.

Hi
If CSMIO can output 24V on step/dir i think that J2S-A is 24V .
Thinks
-
CSMIO/IP-M and IP-S output 5v differential signals.
Hood
-
how i can connect CSMIO to my J2S-A drivers ? If output is 5V and i need 24V .
-
Better do some more reading I believe that the 24volts is only to bring the servo online and 5 volt is used for S&D. +-10 if using analog
-
Yes it would be highly unusual for Step/Dir inputs to be 24v, I have seen that on some drives, Baldor I think, but I would say with almost certainty yours will be 5v.
Hood

HI
I have one other question the IP-M not work on Step/Dir it work with +-10V and he have feedback .... If the feedback is used for follow the mouvement CNC ... IP-M is it best then IP-S.
If i chose the IP-M what pins of driver i need to connect on IP-M... (in +-10V i can probably use the mode speed) .
I think that is my last question .
Many Thinks
-
The IP-M and IP-S are both Step/Dir, the IP-A is analogue. Of the 3 my choice would be the IP-A but it is more expensive than the IP-M and slightly more than the IP-S.
Hood
-
Which pins i need to use on my J2S-A for IP-A
-
You would use the analogue input (+/- 10v) and also use the encoder outputs to pass on to the IP-A so that it knows the position.
Hood
-
Before making my purchase how I can test manually or with a very small electric scheme to turn my engine for both options Step / dir and analog .... just to make sure that both options works work ...
A final issue which auto-check tools you propose me to buy ... i see this but is very poor http://www.ebay.com/itm/CNC-Router-MACH3-Engraving-Machine-Tools-Auto-Check-Instrument-/321113660003
... do you know best tools ...
Thinks
-
You can easily check the speed control by applying a voltage to the corresponding terminals. You can make up a battery box which basically consists of a 9v battery and a potentiometer. The potentiometer allows you to vary the voltage from 0v to 9v and thus you can test things out.
Step/Dir is not so easy, you would have to get a way of supplying a pulse to the Step input on the drive, you could possibly connect up to a parallel port and use Mach to generate the pulses.
Regarding the tool setter, I have never used one so cant advise I am afraid.
Hood
-
i can use function generator tools to do pulses
-
i think that tool setter is good gadget when you change tools manual .
-
This Topic is not open just for Me and Hood ....other people can answer for tools tool setter ;)

Hi hood
I have one question for you My drivers use 1 phase 230V but is not connected to Magnetic contactor is it normal ? Can hi work with no Magnetic contactor ?
Thinks
-
You can connect direct to the mains usually however it is often a good idea to have a contactor to disconnect them but for testing purposes mains should be fine.

Hello Hood
I will go probably with IP-A ... i need a help ... how i connect the encoder with to CSMIO ... In CSMIO have encoder Z + and - ....?
Thinks
-
Most servo drives have an output that passes the encoder signals out of the drive to the controller. Some have to be via emulated outputs, if for example your encoder is a sine/cosine encoder then directly outputting the encoder signal would be no use, so the drive will emulate encoder pulses.
I am not sure what your drives have but I would imagine they would have such signal outputs.
Hood
-
Ok just had a quick look at the manual and there are line driver outputs for Z, A and B.
See pic below.
Hood
-
if you look the page 9 +Z go to -> pulse Z (J2s) and - Z go to -> diff. Z (J2S) ?
is it right ?
and page 9 http://www.cs-lab.eu/en/upload/pdf/Conectors%20CSMIO-IP-A.pdf
-
see attached pic of how you would connect X axis signals.
Hood
-
if me encoder give 24V what i can do to connect it to CSMIO
-
Why do you think it gives out 24v?
It says line driver output and normally that will mean it is 5v. Does it say in the manual that it is 24v?
Hood
-
Because many inputs is 24v or 10v?
-
yes but the I/O for things like enables etc will be 24v but encoder inputs and outputs will almost certainly be 5v.
Hood
-
for a CNC 3 axis what you prefer IP-A or IP-S and why ? I do not which choose ?
-
I have both but the IP-A is preferable to me. Reasons are encoders are fed back to Mach so DROs are updated from encoder position. I switch on, home machine then as long as I keep the logic side of the servo drives powered the DROs in Mach always reflect the axis position.
For example I can disable the servo drives and manually move the axis and the DROs in Mach show the movement.
I can hit a limit switch and the DROs still show the correct position even if the axis moves a bit with inertia.
I can hit the E-Stop and again Mach knows where it is.
With the IP-S or any other controller that does not feed encoders back to Mach then you would need to rehome each time after doing one of the above.
Also you should be aware if disabling a servo or for that matter a stepper you need to re-home when you re-enable it as it has likely moved slightly due to forces such as gravity or belt tension, with the IP-A there is no need for that as it knows exactly how much it moved as the encoders are being monitored.

HI Hood
Can i ask you one other question can you make me one picture how connect the output +-10V ( CSMIO ) to driver .
Tomorrow i test all and buy my CSMIO .

VC and LG are the terminals you use on the drive.

Hi Hood
When i connect my drive and motor to 230V my motor not have any power is very easy to turn it by my hand ... When i turn it by my hand i can see the info . of encoders . Is it normal .
Now can i do this ...
-
LG is it = to GND

Hi Hood
When i put directly 3v to VC ... my motor not run ?
-
Do you have pins 15, 16 and 17 connected to pin 10?
Have you set the parameters in the drive for Speed mode?
Hood
-
yes i connect 15 16 17 to 10 ...but not set the parameters i can not find this ? But, when i connect pin 5 to 10 ...i have torque ?
-
i put the parameter no.43 -> 0111 no.44 -> 0222 no.45-> 0665 no.46->0770 no.47->0883 no.48-> 0994
battery: + to VC and - to LG
-
Do you have the software for the drive? I think that would make it easier to understand and set parameters. I had a quick look and the ones you mentioned above are the default settings so likely they will need changed to suit whichever mode you are in (Speed, Torque, Position)
Hood
-
yes
-
So have you connected the drives up to the software/
Hood
-
i use the page : 3-6 and 5-2 to 5-3
-
yes i can run the motor with software in Test -> JOG
-
if you look in parameter n0.43 to 48 i set it in default .
-
Pg 5-2 etc would seem to be default parameters, you will need to set them to suit the mode you are in.
Ok I have never seen the Mitsubishi software but most drives software allows you to set the modes etc through a graphical interface instead of having to use the parameters, is the mitsubishi software like that?
For example I have attached a screenshot of Giddings and Lewis software.
Hood
-
yes is work one bit have error parameter no.0
-
in drawing of encoder put differential output to GND analog is it ok ? differential output is = to gnd ?
-
Sorry I dont know what you mean.

how i can measure the outputs of encoders
-
You really need an oscilloscope to see the encoders.
Hood
-
i ask a Mitsubishi for voltage of encoders : 5 to 24VDC based upon device it is connected to. Maximum current 35ma.
-
hi hood
my drivers when i apply 0v he continue to run with 1r/min
-
i find the error for 1 r/min ... i measure the outputs of encoders is 5V ...you are the king .
Thinks
-
With analogue controls their will always be some kind of voltage being seen by the amplifier/drive and thus you will have some kind of movement. There will be a setting in your drive to offset things so that Zero is Zero, however that can be problematic and really its not required as once connected to the controller it will offset things for you and make sure the axis is stationary when it is meant to be.

what is the name of plastic for cables
-
Cable trunking is the normal name but can be all sorts, slotted trunking etc
Here is a link to some in the UK
