Technology functions - DC brake (p0300 = 1xx)
To pulse disable
To sequencer
<1> The DC braking current is determined during automatic calculation (p0340 = 1).
<2> The de-magnetization time is determined during automatic calculation (p0340 = 1, 3).
<3> As soon as the standstill threshold (p1226) has been reached, the DC current injection will be aborted prematurely.
<4> Signal r1239.8 is only set while the DC brake is active.
<5> Only for SERVO.
<6> Only for VECTOR.
