Subject: How to tell if a channel is enabled

Tom,

In the script commands there is one listed as "Enabled", but when I try to use it I get the following error from the compiler. 


tcc: undefined symbol 'ENABLED'



I am trying to use it to tell if the 3 axes on my mill are enabled, and if they are then I am setting a bit high which in turn energizes the "drive enable" line in on my servo drives. 

    if(Enabled(0)&&Enabled(1)&&Enabled(2))
    {
    SetBit(144); // Enables servo drives
    }
    else
    {
       clearbit(144); //UN-ENABLES THE DRIVES
     }



Did you remove this script command? How else can I do this? 



I know you spend a lot of time supporting your products and answering posts on here. But I have not seen many say it. So THANK YOU for your time, effort and great products.

Hi Dan,

C Functions and Variables have a different syntax than script commands.  See the KMotionDef.h file for C definitions. 

The Enable state for an axis is a member variable of the axis channel structure.  So it can be tested like this:

        // if all axes channels are enabled then enable the amps
        if (ch0->Enable && ch1->Enable && ch2->Enable)
            SetBit(144);
        else
            ClearBit(144);

Regards
TK

Thanks, that explains why it would not work. Turns out I have hardly a clue what I am doing with C programming. Well back to the books and more reading for me.

Thanks again,
Dan
