powerflex 525. Using the Relay 1 contact (R1 & R2) to apply/release brake.

The following worked for me. Please comment if you see issues.
p45=Ramp+EMBrake (want to display my fault codes on HMI -> no CF)
p76=EMBrkCtrl (my motor brake is controlled via Relay1->Contactor)
p86=0.3s
p87=0.3s
p434=1s
p435=1A (motor FLA=2.1A, so 50% is ~1A)
p436=0
p437=Norml RA Res
p438=100
p550=Disabled
