As explained in 4.6.5 the movement time of the motors
in the diffractometer is increased due to the readout of the wavelength
(done in the diffractometer controller for computing the hkl positions).
This increases considerably the time for scanning any of those motors.
For avoinding this increase in time, set the attribute AutoEnergyUpdate
of the diffractometer controller device to 0.
