• If a basic function is requested again before the brake closing time has elapsed, DC-injection

braking is interrupted and - if activated in C00990

– the flying restart process is started and the

basic function is activated:

Automatic DC-injection braking when quick stop is activated

DC-injection braking is activated automatically if a quick stop is triggered in the drive, e.g. via the

basic function "Quick stop

" or as a response to an error.

• A change-over to the "Quick stop active" function state is effected, and for the quick stop

deceleration time set in C00105

a DC-injection braking process with the braking current set in

C00975

is carried out.

• After this time has elapsed, a change-over to the braking current parameterised in C00974

is

carried out and DC-injection braking is continued with this braking current.

• After the brake closing time set in C02589

has also elapsed, the basic function "Brake control"

automatically sets controller inhibit.

• The DC-injection braking in this case is also carried out when the "Quick stop by trouble" error

response is actuated; however, instead of the "Quick stop active" function state, the "Fault"

function state is active, and the controller is in the "Quick stop by trouble active" device state.
