The pulse encoder sends only motor speed information to the controller.

• A. False
• B. True
• C. Only position
• D. Analog

Answer: (A)

Pulse encoders provide information about both how fast the shaft is turning and how far it has turned. The controller reads the pulse frequency (or time between pulses) to determine speed, and it counts the pulses to know position (accumulated counts for incremental encoders). Absolute encoders even give direct position values, not just relative movement. Because of this, a pulse encoder is not limited to speed data—the pulses encode both speed and position, sometimes with direction information via quadrature signals. So the statement is false.
