<3> 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.
<1> Operating mode, braking control
0 = No brake or brake or brake always closed (brake connected to the power module)
1 = Brake control active (brake connected to the power module)
2 = Brake always open (brake connected to the power module)
3 = Brake control active (brake connection can be interconnected using BICO)
Note: Not all power modules have the ability to connect a motor brake. In this case p1215 is set to 3 and the brake is con
trolled through a digital output (e.g. TM31).
