Siemens SINAMICS V90 Operating Instructions Manual page 141

Braking sequence
The operating principle of the holding brake is configured during motor selection for motors
with incremental encoders and configured automatically for motors with absolute encoders.
The start of the closing time for the brake depends on the expiration of the shorter of p1227
(zero speed detection monitoring time) and p1228 (pulse suppression delay time).
Parameter setting
You can configure the holding brake with the parameter p1215 according to the actual
application.
Parameter Range
p1215 0 to 3
When you set p1215=1, the motor holding brake is open once the digital input signal SON
has a rising edge and becomes closed once a falling edge comes to SON.
