I would like to find out what is the minimum resolution of the PWM signal that the AX500 can recognise ? The document say 0.4 %. I would like to know what is this in terms of milliseconds. Also I would like to know if it is a linear relationship between the pulse-width and the rpm.
Thank you and best regards

The timer used to capture the pulses will measure time with 250ns increments. In the end, the measured pulse is turned in a number from -127 to +127. -127 is the 1.0m (after calibration), +127 is the 2.0ms (after calibration)
