Hall signals are single-ended signals that provide absolute feedback within one electrical cycle
of the motor. There are three of them (U, V, & W) and they may be sourced by magnetic sensors
in the motor, or by encoders that have Hall tracks as part of the encoder disc. They typically
operate at much lower frequencies than the motor encoder signals, and are used for
commutation-initialization after startup, and for checking the motor phasing after the drive has
switched to sinusoidal commutation.

IN5 defaults to the Motemp function but any input may be programmed for that function.
The digital input I threshold voltage is 1.3 2.0 Vdc. A sensor resistance of 351 6667 Ω will
produce those voltages. The BS 4999 sensor example below will produce a HI state for the
Motemp input when the sensor temperature is > 105 C.
