An encoder in a powered device typically coupled to the shaft of a motor. As the motor shaft rotates, the encoder generates a specific count of voltage pulse for every revolution. Those encoder pulses are then read by another device, such as our CLD100-1, and used as speed feedback. Encoders are offered in many different counts per revolution. In motor drive applications, an encoder is most commonly used as motor speed feedback to close the loop of a normal open-loop system. A device such as our CLD100-1 can be used to read encoder pulses. The CLD100-1 in turn generates an analog speed command signal for use by a drive. Using an encoder and CLD100-1 greatly improves the speed regulation of a motor and drive system.
