200*
Assignment of axis to actual-value port (analog)
Default value
0
Simulation axes and spindles are defined if no measuring system has been parameterized (no
servo loop and encoder defined in MD 200* and MD 400*).
The simulation axis derives the partial actual values from the partial setpoints and therefore
"traverses" without any following error. Reference point approach with simulation axes is not
possible. Contour monitoring and P feedforward control are always inactive.

*
MD 200 specifies the servo loop module or input for incoming actual position values.
All servo loop modules are interfaced to the same bus and are therefore numbered
automatically from left to right by the software on POWER ON. There is no wiring block for
these modules.
NC MD 384* is used to define the setpoint outputs.
Note:
See Section 5, Machine Data Dialog, for the servo loop assignment.
