Function chart number:
The positioning down ramp (enabled using P0500) can be used for applications
where it is necessary that a residual distance is moved-through up to the stop
dependent on an external event (e.g. BERO switch). In this case, MICROMASTER
440 generates a continuous braking ramp by selecting OFF1 depending on the
actual load speed / velocity. The drive is then stopped/positioned along this braking
ramp (refer to Fig. 3-64).

In this case, the remaining distance P2488 moved through must be entered,
referred to the load. In order to carry-out the residual distance calculation on the
load side, the mechanical arrangement of the axis (gearbox ratio, linear or rotary
axis) must be appropriately parameterized (refer to Fig. 3-65).
