U_output
<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 braking is active.
<5> DC braking upon falling below the starting speed for DC braking (p1234).
