11.3.4.2 DC-injection braking when quick stop is activated

If DC-injection braking is activated in C00976 instead of quick stop, DC-injection braking is executed

automatically when quick stop is activated.

• After activating quick stop, 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.

• 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.

 Note!

The quick stop braking current in C00975 has to be set so that the drive can be

decelerated from the maximum operating speed to standstill within the deceleration

time for quick stop set in C00105
