Function Diagrams And Parameters - Siemens Sinamics S120 Function Manual

Basic functions
6.10 Armature short-circuit braking, DC braking
Using parameter p0491, responses to encoder faults of a motor encoder can be set (F07412
and many F3yxxx, y = 1, 2, 3).
Note
Motor type change
If the preconditions for armature short-circuit braking or DC braking are no longer satisfied
after a motor type has been changed (see p0300), then those modified parameters that have
armature short-circuit braking or DC braking as a response (e.g. p2100, p2101 or p0491) are
set to the factory setting.
Note
Deselecting armature short-circuit or DC braking
Armature short-circuit or DC braking cannot be deactivated using parameter p1231, as long
as a response parameterized with p2100, p2101 or p0491 has a fault condition.
