Brake control - expanded brake control/opening and closing a brake (r0108.14 = 1)
Function diagram
<1> Motor holding brake configuration
0 = No 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 controll
ed through
a digital output (e.g. TM31).
<3> These blocks/modules are evaluated with the same sampling rate as the brake control and therefore may only be used to
individually adapt the brake control.
