L3: Stall Prevention Function

Use L3 parameters to configure the stall prevention function.
Selects the stall prevention method used to
prevent excessive current during acceleration.

ignored. Acceleration is completed in the
shortest amount of time without exceeding the
current value set in L3-02.
