Display Slow Jog in IPM
« on: December 24, 2011, 02:33:03 PM »
Is there a way to display the Slow Jog rate in IPM instead of as a percentage with OEMDRO 3?

There a DRO 829 that might be what you want, but it's not listed in the Wiki?

Otherwise, you could create a USerDRO to display the IPM, and use a Brain to do the math and write the IPM to it.

Thanks for the reply.

I tried DRO 829, but it stays unchanged at 0.  It shows up in the Brains editor, but it's not identified in the MachScreen editor.  I tried writing a Brain.  I can get the Jog % value, but I don't know how to access the number to multiply it by.  It appears to be the maximum Velocity from the motor tuning of whatever axis I'm jogging.  Any suggestions?

This number would be very helpful when using my pendant to do a Constant Velocity move.  I can look at IPM and tell if the cutting speed looks OK, but I don't have a feel for percentages!

GetParam(VelocitiesX)
But I don't know how to use it in a Brain, unless you write it to a User DRO first maybe. I don't use Brains enough to give much more help, but it looks like you need to use a formula
