Re: IM804 datasheet

----------------------------------------------------------
Take the motors RMS current X 1.4
This will give you the peak current.

Peak Current X 500 = Resistor (pin 2-3)
(5amps = 2500 ohms 1/8watt)
-Connect resistor directly to pins, use no wires.

Do you want the decimal table also?
It's almost the same but in steps of 1000, 2000, 5000.....

Anything else?
