input voltage for the output driver stages
position generator: input from the position detector sensor to the
position detector stage (optional); only if an external position coil
is used
position generator/frequency generator: output of the rotation
speed and position detector stages (open collector digital output,
negative-going edge is valid)
ground supply return for control circuits
