The spindles available on the machine can be allocated to the measuring circuit modules in a
flexible way. They are allocated separately according to actual value inputs (MD 400*) and
setpoint outputs (MD 460*).
Simulation axes/spindles are defined if no measuring system is parameterized (measuring loop
and encoder not entered in MD 200*, MD 400*).
The simulation axis/spindle generates partial actual values from the partial setpoints and
therefore travels without following error. (For more detailed description see MD 200*).
Note:
See Section 5, Machine Data Dialog, for the servo loop assignment.

The input value must be modified in the appropriate direction until the spindle exhibits identical
actual speeds in both directions of rotation. The value must be adjusted at low speeds, and
can be checked by viewing the appropriate information in the Basic display in the service
display for spindles (spindles with encoder), using a rev counter, or screening the Service
data. In M 19 (spindle positioning), the spindle drift goes directly into the positioning error.
