FCB 10 Interpolated position control
FCB 10 is used for cyclic preselected position setpoints from higher-level controllers.
In multi-axis applications, a higher-level controller usually calculates a track profile for several drive axes. The axis only receives setpoints (position, speed, torque, torque limits, precontrol values, inertia), which it must follow directly. The axis limits the setpoints using the application limits. The path curve profile is controlled by the controller.
The setpoint cycle of the controller usually does not correspond to the setpoint cycle of the axis. If the axis were to "see" the same setpoint for several cycles, a step-shaped actual value would result. To prevent this from happening, the axis interpolates intermediate values. To do so, the setpoint cycle of the controller has to be known.
