The output of the acceleration command summing junction signal passes through
a limiter to produce the Acceleration Reference signal. The Accel Limiter applies a
directional acceleration limit, either the Acceleration Limit or the Deceleration
Limit, to the input command signal based on the sign of the signal.
The following diagram illustrates this process.
