2.2 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.
