Figure 3.3: Controlled ramp-down, longer line failure. Ramping down as long as the energy in the system allows for it, then the motor is
coasted.
Figure 3.4: Kinetic back-up, short line failure. Ride through as long as the energy in the system allows for it.
Figure 3.5: Kinetic back-up, longer line failure. The motor is coasted as soon as the energy in the system is too low.
