In brake logic, p1275.5 (Brake with feedback) should be set to "No". The brake
checkback should be evaluated using the Brake Feedback function of the
ExtendedCraneDCC.
Figure 2-3
In brake logic, p1216 (Motor holding brake opening time) should be set to 0 which
avoids the delay in the operation enabled status word of the sequence control.
Instead, brake release time should be configured in p21902 (BrakeFeedback_
BrakeReleaseTime (ms)). Also, p1217 (Motor holding brake closing time) should
be set to 0 and instead, brake closing time should be configured in p21908
(BrakeFeedback_BrakeCloseTime (ms)).

In brake logic, the below settings are necessary in "Close brake" logic.
