The encoder resolution of incremental encoders influences the control quality of speed and position control:

  • A simple, non-dynamic positioning can be implemented with HTL encoders with low resolution (e.g. EI7.). In addition, those encoders allow you to inexpensively check whether the motor is turning. These encoders are insufficient for speed control because increased speed noise is expected, especially at low speeds.
