<1> This pulse enable path only works for operation with brake (p1215 > 0).
<2> When braking with a feedback signal, the inverted signal is interconnected to the BICO input for the second feedback signal. The brake switching times are set in p1216 and p1217.
<3> Only when Safety Integrated is activated (Double Motor Module: X22, Chassis: X41).
<4> When the master control is retrieved, entered from STARTER or AOP.
<5> If an external motor holding brake is used, then p1215 should be set to 3 and r1229.1 should be used as control signal.
<6> Internal signal contains signals that result in OFF1 or OFF3 such as e.g. BICO or fault response.
<7> When the function module "extended brake control" is activated (r0108.14 = 1), r1229.1 should be interconnected as control signal.
