MOTOROLA
by a squaring circuit. The generated square signal is fed to the
microcontroller Input Capture block of the Timer A (Channel3). The Input
Capture function reads the time between two subsequent rising edges of
the generated square wave. The measured time corresponds to actual
speed of the motor.

3.7.2 DC-Bus Voltage Sensor
The DC Bus voltage must be checked because of the over-voltage
protection requirement.
A simple voltage sensor is created by a resistor divider. The voltage
signal is transferred through the isolation amplifier and then amplified to
the 5V reference level. The amplifier output is connected to the A/D
converter of the microcontroller ATD1.
