Motor contactor 1 is opened (r0830 = 0) and the status bit "Motor data set changeover
active" (r0835.0) is set.
The requested data set is activated (r0051 = requested data set).
After the feedback signal (motor contactor opened) for motor contactor 1, the appropriate
bit of r0830 is set and motor contactor 2 is energized.
After the feedback signal (motor contactor closed) for motor contactor 2, the bit "motor
changeover active" (r0835.0) is reset and the pulses are enabled. The changeover is
complete.
