Speed Assignment
This test is only necessary in the case of servo drives (MD61 = 0).

Use the following flow chart to check that the speed assignment of the drive
corresponds to the parameterization in the machine data.
If you have carried out the "Check encoder actuation" startup step correctly,
with each traverse, the actual traversing velocity of the machine axis will be
shown on the "Velocity" display.
This test has to be conducted in order to ensure that the parameterized
