I'm trying to configure a Maxon ECX BLDC motor. During the configuration step where they ask you to choose the step count for the incremental encoder there's this "information on resolution" note box that says to follow this basic rule: "As high resolution as necessary"
Given that the price for the sensor is the same for different step counts, why do they say this?
- Wouldn't higher step count always be better since it provides better resolution (degrees/step) thereby allowing for finer position/speed/force control?
- What are the disadvantages of having way higher encoder resolution than is needed?
