I think the reasoning is EMC2 never ALLOWS you to actually get beyond the soft limits, it is impossible by software control only, to actually trip this limit. In the case of an encoder-equiped machine, I think you could home an axis, go to estop, manually crank the the machine past the soft limit, and then when you come out of estop, it would trip the limit. I don't know whether the HAL pins would then show the limit exceeded condition. Jon -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

[Emc-users] Pulley ranges and VFD's
Is EMC aware of pulley ranges for spindle speeds? For example, my lathe has three ranges, Pulley 1 gives me 0-750 Pulley 2 0 - 1500 Pulley 3 0 - 3000 How would this affect spindle speed control? If I command S1000 in pulley 2 my VFD expects 6.6 volts, but only 3.3V in pulley 3 range. Steve Blackmore -- -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

Re: [Emc-users] Pulley ranges and VFD's
I have been working on a spindle component that can handle up to 16 gears. For each gear you can specify the acceleration, deceleration, min speed, max speed and output scaling. If you have a spindle encoder it uses the feedback to limit the acceleration based on spindle load. It also provides a filtered spindle speed output for a spindle speed display. I still need to do some cleanup work but it is working well on my lathe. I'll release it once I have finished tidying it up. Les I wrote a simplistic 2-gear component, called gearchange.comp.
