What happens if I try to start the drive into a freewheeling (spinning) motor?

Starting a drive into a freewheeling motor creates a direct short-circuit and may result in damage to the drive. To bring free-wheeling loads such as fans to rest before starting, use the DC injection braking function, and confirm that the motor is suitable for DC injection braking. Alternatively, consult parameter P110 for flying start/restart options (settings 5–8), which allow the drive to perform a speed search and catch the spinning motor. (Page 16)
