FCB 26 Stop at user-defined limits

FCB 26 is used for stopping at user-defined limits. The user-defined limits are either available as local setpoints or initiate the downward ramp via the fieldbus with adjustable parameters. You can choose between a speed-controlled ramp and a position-controlled ramp. Unlike the other stop FCBs (FCB 13/FCB 14), FCB 26 has a very low priority.

This makes it possible to select FCB 26 by default (e.g., the bit in the control word that selects this FCB is always TRUE). This means that FCB 26 is always active when all other FCBs are deselected. This makes it possible to always stop in a position-controlled manner.

In position-controlled mode, FCB 26 has lag error monitoring. When the stop is reached, the brake remains released and the motor remains energized.
