dspMC/IP Motion Controller / ModBus and dspMC/IP
« on: November 19, 2011, 04:48:38 AM »
Is it easier to use one of the Vital Systems breakout boards (7535 PnP board) to control the spindle VFD via digital inputs on the VFD intelligent terminals or use the capability of the ModBus functionality of Mach 3 to control the spindle?

Thanks,

Todd

Thanks for the reply I guess just possible expansion or need I will save for the model with analog inputs.

Which model do you have?

What is the difference between the DSP/MC "S" and "M" models?

TIA

General Mach Discussion / Need advice
« on: February 09, 2007, 11:24:06 PM »
Hello:

Thanks to all that have put this site together and others who contribute to the forum.

I need some advise.

I have a Bridgeport Series I Mill that I bought from a state auction. I looked at the machine after I bought it and I thought man this guy is sick. I weighed the thought of trying to sell the machine on Ebay and other sites. I was able to power the machine up and discovered it was worse than I thought.

Then I discovered MACH3, man what a great product. This got me fired up and began reveiwing all my Home Shop Machinist issues about computers in the shop and discovered that maybe I do have a gem.

The system was an original  Heidenhain TNC 150 but was upgraded in the mid 90's to a Dynapath CNC. The ways all still have the jewelling and the machine feels tight. The table does not show any "student" abuse.

The machine has SEM DC brushed servo model MT30R4 - 58 motors 3.2 NM at 2500 max. rpm @ 145 VDC.  It has Heidenhain shaft mounted encoders (125 line count) with multiplier box (X 5) TTL output. The total resolution is what I figured to be (125 * 4 * 5 = 2500 counts).  The ball screws are 5mm pitch screws and the servos are coupled via cogged 2:1 belt drive. The servos are connected to Bosch legacy Z15 - 1 - 240A drives. The drives unfortunately require 0 - 10 VDC command for step and direction control.

I have also a 2.4 GHz motherboard and all the PC stuff for the controller.

I am wanting to use as much as possible of the original equipment to upgrade the machine and start making some chips (budget). I have read as many post from the MachSupport groups and the Yahoo groups, but need some good sound advise on other hardware
selection(s).

I am undecided on a breakout board selection, I have looked at all the usual selections. They seem to all be good products but what is the best value, has the most features and works the best with Mach3?

I plan on single phasing a small 2 H.P. VFD for spindle control. The machine has a variable speed head but would prefer software to control the spindle. So speed control is a important feature to have.

I would like to use my existing drives if all possible. I have looked at the Pixie product and hope that this will aid me with my existing "dumb" drives.

I would also like to use a MPG and different latched outputs (i.e. coolant, lube pump and VFD control).

What is some products that you guys have used and are fond of? What products do I need to stay away from. I want to make good, smart economical decisions. No do-overs or expensive mistakes.

Thanks in advance from everyones advise and I look forward to conversing with you all.

Todd
