braking)
Access level: 2 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: MDS, p0130
Unit group: - Unit selection: - Function diagram: 7017
Min:
0.0 [s]
Max:
3600.0 [s]
Factory setting:
1.0 [s]
Description: Sets the DC braking time (as fault response).
Dependency: See also: p1230, p1231, p1232, p1234, r1239
p1234[0...n] Speed at the start of DC braking / DCBRK n_start
CUG120XA_USS (DC
braking)
Access level: 2 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: MDS, p0130
Unit group: - Unit selection: - Function diagram: 7017
Min:
0.00 [rpm]
Max:
