The BU register indicates if the motor and thereby also the turntable or turn device are
currently moving.
For mechanical reasons, the motor cannot start immediately after the receipt of a start
command.
Therefore it is necessary to wait until the turntable moves (BU = 1), before it is possible to
enquire with BU whether the previous command has been completed. If the mast is already
located in the desired position when a GO command is received, BU will nevertheless be set
on 1 for approx. 0.5 sec.
