Zero-clamp function
This function is used for a system in which the host controller does not form a position loop.
In this case, the stopping position may shift even if a speed reference is set to 0. If the zero-
clamp function is turned ON, a position loop is internally formed so that the stopping position
is firmly “clamped.”
