As an illustration, consider an encoder with an operating frequency of 150kHz and a maximum shaft speed of 1,200 RPM.

The max encoder resolution can be computed using the following formula:

Max Encoder Resolution = Operating Frequency x 60 / Max RPM

Plugging in the values:

Max Encoder Resolution = 150kHz x 60 / 1200 RPM = 7,500 pulses per revolution (PPR).

This suggests that the encoder, under these conditions, would support a maximum resolution of approximately 7,500 PPR.
