3.6 SME external devices description
The Controller can be connected to SME external devices described below.
3.6.1 Quad Encoder
Quad encoder can detect the rotating motion of the toothed wheel fixed to the motor shaft and it
generates two electrical signals (square wave and open collector type), usual for kind of encoders.
The two output signals, named channel A and channel B, are shifted by 90 electrical degrees. Their
frequency is proportional to the rotational speed of the motor shaft. Since the toothed wheel has
64 teeth, each channel generates 64 pulses every complete turn of the shaft.

Sin/Cos Encoder
Sin/Cos encoder is composed of a magnetic actuator that must be mounted on the motor shaft
and a sensor board. Rotation of the actuator is sensed by the encoder board, and processed to
give for output sine and cosine waveforms.
