Question about Soft Limits

[czralv]

I found an old post regarding soft limits where the code below was used to monitor an axis and set a virtual bit if outside the soft limits.
It was suggested to use the "Disallow drive into limits" setting to have the axis watch the virtual IO bits for those limits.

If I already have hard (real) limit switches, and have the "Disallow drive into limits" watching those Input bits, is there any way to also have the axis watching the Soft Limit virtual bits with the "Disallow drive into limits" feature ?

Can I enter two bit numbers into the "Disallow drive into limits" dialog ?

Thanks


#define COUNTS_PER_MM 200.0
for ( ;; )
{
WaitNextTimeSlice();

if (ch0->Position < 10.0 * COUNTS_PER_MM)
SetBit(48);
else
ClearBit(48);

if (ch0->Position > 300.0 * COUNTS_PER_MM)
SetBit(49);
else
ClearBit(49);
}

Hi czralv,

No you can't specify multiple limit bits. But I think you could "OR" in the Hard Limit Bit with the Soft Limit Condition. Something like:

if (ch0->Position < 10.0 * COUNTS_PER_MM || ReadBit(HARD_NEG_LIMIT)
SetBit(48);
else
ClearBit(48);

HTH

That'll work, thanks so much.
