Wiring my PM 727v spindle motor to KBSI-240d board HELP

If your acorn board outputs a 0 to 10 volt signal you may need to divide it down to a 0 to 5 volt signal like this:
The two resistors would have the same value, perhaps 1k or 2k ohm
Check the value of the pot it may be printed on it or you could disconnect it and measure it, it's probably in the range of 5k
On the kbsi-240d board there are trim pots that allow the user to adjust the low end ( 0 volts ) to read 0 RPM on the motor and a trim pot on the high end ( 10 volts ) to adjust the max RPM. Can I use this to the the same results as you are describing ? They are the blue pot in the picture

Just an update for people reading this in the future I did end up using everyone's advice as explained in the above post and was able to get control over the spindle using the instructions. A big thanks to everyone involved that gave helpful info and I hope someone else finds this helpful on down the road
