Hello Hood and everybody;

i have a dspmc from vital with 7535 IO card to ritrofit a machine.

i just start to analyse the machine and to think about how to write and develop some macros to control it.

now i have a problem in how to check  if an input ( i.e. User Led 1300) is triggered with in10seconds after the ouput was activates.

in other meaning , i want to check if my Pneumatic Piston done it's complete strock with in Maximum of 10 seconds. otherwise the Macro sends an Error message to the mach screen.

Note that the input could be triggered in 3-4 seconds . and so i dont want to lose 7 seconds in waiting for the inputs(Userled 1300)

if you any suggestion please let me know!!

Brains Development / Re: Spindle Contactor Brain, with Delay.........
« on: September 17, 2014, 04:03:28 AM »
hello Freinds;
 i am really new Brains user so with Mach 3.

i want to Create a brain for safety:

the brain sholud check in an input is trigged (ON) after an output is done:

Example:
if output #1 is ON i must get an input #2 after 3 seconds.
if i dont get the input after 3 seconds i need to to hold the machine and send a messege Error to the screen.

i want to secure that the my pneumatic piston finish the stroke within 3 seconds and the machine dont continue.

by the way the most important for me is how to send a message to the "Error message: in mach 3 using Brains.

dspMC/IP Motion Controller / Re: Spindle settings
« on: May 13, 2014, 12:35:20 AM »
hello Freind,
thank you for the helpful info.

but my question is it possible to do the same code in the SCode instead of Mcode

i mean to add the above code in the spindlespeed Macro in mach3\macros and to use the S instead of M and to get the desired RPM by GetRPM()

how can i do that??

hello freinds
i have a similar problem with Acc\Dec rapm setting with BOSCH ASM 60 TA Type.

i think this VFD has no option to control Acc\Dec ramp Up/Down (has no key pad or parameters to set).

in my opinion the Bosch CC100 cotroller controls this and sets the analog voltage for the VFD.

in my case, i want to use the Vital DSPMC to control the spindles.

so how i can control the ramp Up\Down with the DSPMC.

is there any option to do that using Brains for example???
e.g. setting s=1000 then s=1500 then s=2000 ....untel the desired S=16000.

Hi Matt and Hoodand everybody;

i have a question to Matt about the bosch ServoDrive hes have.

i understood that its Bosch SM 10/20, So what about the encoders connection??

do you have a connection between the encoder and the driver???

what is your encoder voltage?? 5vdc or 15vdc.
whitch voltage supplies the sm10/20 that you have to the encoder.
what about the tachometer connection? did you connect it the DSPMC??

i have the same drivers system and i want to retorfit it the machine using MACH 3

my proplem that i have no Electrical Docs for the machine (very old-1994). and also i have no Docs for the drivers(also in BULLERI -italy they have not).

anybody can help me??

regards'

General Mach Discussion / Re: How to use Mach3 outputs?

Hello friends,
I want to know how I can control a relay contact in mach3?

I have a pneumatic valve controlled with 24vdc relay.
What I need to do is to define  a new Mcode (i.e M77) and to refer it to a free output from mach3.
 When M77 in process, the relay is activated until been reset by M78 for example.

Has anybody an idea??

Ghantos

hello friends;

i have a machine with homing and limit switch separatley.

the machine is doing the homing process proparly.

i ask if its possible to drag off the home switch (mechanical switch) more than closing the switch again.

in other meaning, i want the axes to return back more to free the switch more(i.e 10mm more drag off) and then to zero the DRO's
 
i hope i explain my self well.

hello freinds'
i have a router with 4 parallel spindles in fixed in Y.(Bulleri Fpm2613-ITALY).
the distance between the  4 spindlels (center to Center in Y) is 300mm.
no tool chainger it has only alternate spindles(activte one , decative the othes)

the machine is controlled by Bosch CC100 controller and now i planning to retrofit it using MACH3.


normally i use 4 different tool, one on each spindle.
Gcode for controlling tool change(only alternate spindle)
T1 M6 M66 is the first tool(the first spindle)
T2 M6 M67  is the second tool ,second spindle
T3 M6 M68 is the third tool , third spindle.
T4 M6 M69 is the forth tool forth spindle.

my question is how to set the machine Origins and fixtures in MACH3 to shift the difference of 300mm in Y automaticlly to get the same Coordinate point in y when i change the tool.??
regards

hello  Freinds;
really i started to retrofit my CNC machine and i found this post as a great reference.

also me have CC100 bosch control that i need to replace with MACH 3

i have bosch sm 10/20 servo drive and i know that i need DSPMC motion controller for using analog DIf. +/-10vdc to control

SW+ and SW- are the analog inputs for the control.

But, its not clear to me the Encoder and the tachometer connections.
in the elect. layout of the driver looks like the encoder and the tachometer need -+15vds power supply but the DSPMC tacho and Encoder are 5vdc?? ??--any idea about?

also, in the elec. layout its seem that the Encoder cable comes directly to the Servodrive (no connection to the controller) is it logic???

if anybody do this job before please let me know!!

regards
