4.6 Power Control Commands & Queries
A key advantage of the constant current motor control drivers used in the Pan-Tilt Controller
is that it allows the current consumed by the pan-tilt unit to be controlled via simple unit
commands. These capabilities are useful for battery powered operation (see Section 7), reducing
unit heat generation, and extending the rated life of the motor driver circuitry.
