Illustration 4. 3: Controlled Ramp-down, longer mains failure. Ramping down as long as the energy in the system
allows for it, then the motor is coasted.
Illustration 4. 4: Kinetic Back-up, short mains failure. Ride through as long as the energy in the system allows for
it.
Illustration 4. 5: Kinetic Back-up, longer mains failure. The motor is coasted as soon as the energy in the system
is too low.
