Yes, Mike, Thank you. Outrunner.
I got ahold of the PoKeys support group and they gave me the solution as follows.
The best way is to use PoBlocks and set the desired speed via PoIL shared slots.
In PoBlocks, you can use the 'Extended / Re-scale' block to scale the 0-max rpm to 1 to 2 ms PWM signal duty cycle and feed this into the PWM output block inside PoBlocks.
They are very fast with their customer support, Kudos to PoKeys for outstanding support!!
