This function allows the restart of a coasting motor without the necessity to first
stop the motor rotation. It is useful during drive bypass operation, when switching
between the motor receiving power directly from the line and from the drive.
The FWD (REV) run command must be input at the same time as the search
command, or within 0.5 sec. after the search command. If the run command is input
before the search command, the search command is disabled.
