dspMC/IP Motion Controller / Timer with analogical inputs

« on: October 10, 2011, 08:25:39 AM »

Hi.

I need a way to read in Mach3 the value of DSPMC card time when the analogical input DRO has updated.

I need to have in Mach3 not only the value of analogical input, but also WHEN it was red by DSPMC (and not the time when Mach3 had received it, because it should be not the same, and it should depend by buffer ...).

And more, in the guide of DSPMC I find that frequency of analogical inputs is 10kHz. But also if I read up to 8 inputs, frequency is the same, or I must divide the max value of frequency by the number of inputs reading together?

Thanks for your help!

Brains Development / Re: Brain to control limit switches

« on: September 30, 2011, 09:25:06 AM »

Hi.

Thanks for your answers.

Unfortunately not good news for me.

Yes, I know that user can see where axes goes when he moves it, and he must do it carefully if he is near or on a switch.

But I wanted to prevent also a careless operator, to prevent damages.

In this way, it is also the will to control jog pression for example if "soft limit" are disabled.

But I understand that a solution isn't...

Thanks anyway.

Thanks. This is half solution to my trouble.

I try to use limit override and I can return to move axis after switch pressed. But with a brain I want to prevent the motion in the way of the switch: this is the second part of my question. And I can't find in brains inputs how to do...

Does anyone answer?
It is important for our work.

Brains Development / Brain to control limit switches

« on: September 26, 2011, 07:30:39 PM »

Hi.

I need to control what it happends when machine arrives on a axis limit switch.

If I configure as a axis limit the switch, when it i pressed, reset state goes down and the switch stay on. In this case, I cannot move axis to bring out the machine from the switch.

So I should want to control the switch signal with a brain in this way:

- if user press jog key, brain controls if the machine is on the limit switch. In this case, it is inhibit moving in the sense of switch, but it is possible to move in the other way.

BUT!

When I look for the jog pressed button in brain inputs, I cannot find what work in this sense. There is not way to check the pression of 307 or 308 Button??? (for X moving, i.e.)

Please help me if you can! Thank you!

dspMC/IP Motion Controller / How to configure a MPG

« on: April 04, 2011, 05:09:10 AM »

Hi.

I'm sorry for my imperfect English.

I've started to use VitalSystem board with Mach3 in the University Laboratory for my degree.

We have problem to connect softencoder for MPG use.

Reading the guide I know that for the first MPG I can use pin 24 and 12 on J4, that means I must connect A and B channel of softencoder on I12 and I13 pin of 7535 board. (and 5V and ground of encoder on power pins of 7535)

Later, I must config MPG in Mach3. I've used the config panel directly from Config Plugin in the Setting Menu, on page 1, and also I have written in the xml section:

<MpgSource1>
             <Type>SoftEncoder</Type> <!—SoftEncoder or HardEncoder-->
             <Index>0</Index>
</MpgSource1>


In input/output page of Mach3 I set only MPG1 enabled, and unit/count in relative column, without setting numbers of ports and pins for A and B channel, as the manual says.

Now. Where's the error? How can I read pulse from the encoder?

Obviously, I write this topic because setting MPG mode on the jog, and selecting a axes, the machine doesn't move itself.

I tried to write VB script, or brains to read UserDRO 1330. Nothing.

We have controlled encoder separately, and it works.

Thanks for your answer.

Bye!
