Multi-speed and acceleration/deceleration time

Different acceleration and deceleration times can be set for each multistage speed. The acceleration

time is the one used between the current speed and target speed during acceleration. The deceleration

time is the one used between the current speed and creep speed (speed-7), or between the current

speed and the target speed during deceleration. Therefore use the deceleration time of A027 for creep

speed at stopping. Furthermore, inverter decelerates with the deceleration time that is set on that

multistage speed when the RUN command is removed.
