Hood,

 3000 / 60 = 500? Looks like the ol' Casio may be ready for new batteries.... :-)

oops, bit of a typo there but the final figures are correct I think ;) just put an extra zero in, I have an excuse, I was running the mill, the lathe and also drawing a ciorcuit board up while I was working it out and replying , well thats my story and I am sticking to it ;D

Hood,

    Doing all that, it's a miracle you didn't spill your Scotch!  :-)

I have various means of doing that, first thing is my Step/Dir inputs to the drive are 5v and I would imagine the Yaskawas would be the same, so no need for anything there. The rest of the I/O on the drive is either through a PLC or things like limits are through relays to the PC.

Just through the manual again n found that they have two options for driving the position pulse.
a) line driver.........it uses 24vdc power from drive itself n a current limiting resistor.
b) Open collector ............its external supply n different resistance value for optocoupler.


I guess B is for 5Vdc signal. Should i go for it.

Hood,

Can we use HID device or Joystic Port with Mach3 ....for analouge input signals. Or we just have MODBUS for external devices.

Think the only  analogue inputs at the moment is ModBUS, hover the PoKeys should hopefully have them shortly. Art is working on a plugin to take adavantage of MPG inputs and Analogue Inputs.

Looks like you should be able to use the 5v for the Step/Dir inputs to the drives, would just need a suitably sized current limiting resistor.

There's and open source diy available.................... http://1010.co.uk/avrhid.htm l..........................if this goin to work with mach, don't u think we can have ProPad kind of stuff added to our Mach.
For plugin ......its up to Artsoft how much they can support n how many users want it customised.

Should we get this on FEATURE REQUESTS

Thanks for confirming ster/dir issue.........let me hard-wire them this weekend

Your link seems dead. If you are capable of writing a plugin then you can use almost anything you want with Mach, I believe there is a SDK for writing plugins.

Not really confirming that you can use 5v Step/dir inputs but certainly looks like you can from the pics you posted above.
