= 3: ON with pick-up (flying start)
If the run command is ON at the power ON time, then the drive will start once the pre-
charging is completed, enabling the pick-up function. This mode is useful to start after a
power interruption.
When the drive is used as vector control with sensor, the pick up is not needed even if
the motor is rotating when the drive re-starts. In this case set C08-0 to 2
