Description:
Sets the braking current for DC braking.
Dependency:
See also: p1230, p1231, p1233, p1234, r1239, p1345, p1346
Note
A change to the braking current becomes effective the next time that DC braking is switched on.
The value for p1232 is specified as an rms value in the 3-phase system. The magnitude of the braking current is the
same as that of an identical output current at frequency zero (see r0067, r0068, p0640). The braking current is internally
limited to r0067.
For the current controller, the settings of parameters p1345 and p1346 (I_max limiting controller) are used.
