What is indicated by a motor value of 128?

A motor value of 128 typically indicates a neutral or "off" position for a motor controller. Many motor control systems use a range of values, often spanning from -127 to 127 for direction and speed control. In this context, the value of 128 usually corresponds to zero speed, meaning the motor would not be activated and would remain stationary.

When considering the other options, full speed in either direction would typically correspond to values of 127 for clockwise and -127 for counterclockwise. Therefore, a motor assignment of 128 wouldn't yield any actual movement, affirming that it would effectively turn it off or maintain a state of inactivity. This aligns with the understanding that a motor control system is designed to interpret the midpoint value (usually around the center of the range) as an off state, as is the case with 128.
