Motor Regeneration with VFD | Information by Electrical …
The problem is that as the motor reduces its speed it increases the voltage on the DC bus of the drive. The only ways to handle this are: to length the time that the motor is slowing down (increase the deceleration time) or to bleed off the increased voltage by using braking resistors, or in fancy drives by adding a re-gen package and putting the voltage back into the …

AC1
The speed set point doesn't go instantaneously at 1800 rpm but follows the acceleration ramp. The motor reaches steady state at t = 1.3 s. At t = 2 s, an accelerating torque is applied on the motor's shaft. You can observe a speed increase. Since the rotor speed is higher than the synchronous speed, the motor is working in the generator mode.
