7.7.1 Using the brake/DynaStop
®
in conjunction with STO
To use the DynaStop
®
function in connection with the STO function,
SEW‑EURODRIVE recommends control using the safety function SS1(c).
To do so, the parameter Behavior at standstill must be set to "Brake applied/drive not
energized" (path: Functions > Drive functions > FCB02 Stop default).
The following table shows the behavior of the DynaStop
®
function depending on the
parameter setting:
