Hi Tom,
What do I need to interface IO26 to a VFD 0-10V to achieve proper isolation and good signal levels?

What outputs would I choose to use the Beacon adapter I have described in Bengt's Combimill folder?

Also I am planning to add 2 MPG's one for each axis in my lathe, what I/O's are best suited for this?

Assume that I can use JP4 for selecting X1 X0.1 X.01 X.001 for the use of my 'hand wheels' on my lathe when I want to use lathe as 'manual'.

Cheers
Bengt

Hi Bengt,
 
To convert Digital IO26 PWM to an analog signal you would need a 3rd party converter.  I mentioned before a software PWM commanding an opto output driving a capacitor might work.
 
It looks like you already chose Opto Outputs 0 - 3 (IO144 - IO147) for your Beacon.
 
Most users use the Aux0 connector for MPGs.  The inputs are actually only 3.3V inputs but the firs 8 IOs have 150ohm pull down resistors and if your MPG doesn't drive higher than 3.8V with that load it works fine.
 
Yes.  The MPG control is a software user program so you can use any IO and have any step sizes you wish.
 
Regards
TK

Hi Tom,
Ahh.. Now that you meantion it i remeber, have to look at suitable converter. Regarding Beacon IO144-IO147 that is Kanalog and my mill but now it is my Lathe with only Kflop. Aux0 is OK then, I will use HEDS-5700 ENCODER 2CH 500CPR. These are 5V encoders so I will be using the same level converter I have for the mill (MPG schematics in the mill folder) and just use other IO's.
Cheers Bengt
