Flying restart process

The controller calculates the output frequency required for the momentary speed of the coasting

motor, then connects to the system, and accelerates the motor to the defined setpoint again.

• The flying restart process serves to prevent the motor from decelerating to zero speed with

subsequent acceleration.

• The currently detected flying restart speed is provided to the application via the current motor

speed MI_dnActualMotorSpeed_s.
