<1> This pulse enable path only works for operation with brake (p1215 > 0).
<2> For brakes with one single checkback signal, the inverted signal has to be interconnected to the BICO input for the second checkback. The switching times of the brake are set in p1216 and p1217.
<3> If an external motor holding brake is used, p1215 should be set to 3 and r1229.1 should be used as control signal.
<4> The internal signal comprises signals that lead to OFF1 or OFF3, e.g. BICO or fault response.
<5> If the function module "extended brake control" is active (r0108.14 = 1), r1229.1 should be interconnected as control signal.
Note: Braking signal diagnostic evaluation (p1278) is only relevant for SBC (Safe Brake Control) (controls the Safe Brake Relay).
