Speed feedback is provided by a slotted encoder wheel and optical sensor. The
IR output of the sensor diode is interrupted by slots in an encoder wheel attached to the
motor shaft. The IR sensor output is filtered by C37, C67, and C66. The offset is
removed by C68 and level shifted by R125 and R127. U12C compares the sensor
output against the reference level formed by R94 and R126. R109 provides hysteresis
