Description
The positioning ramp down 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, the SINAMICS G120 generates a continuous braking ramp by selecting
OFF1 depending on the actual load speed and velocity. The motor is then stopped and
positioned along this braking ramp (see figure below).
