Figure 8-21 Interconnection for "Enable output-side breaker"
The breaker must also trip in the event of a converter fault. This is achieved using the
specified interconnection.
To activate the interconnection, parameterization (in the expert list) must be carried out as
follows (in this example, it has been assumed that the drive is called "Drive_1" in the project
navigator):
● (TM31) p4030 = (Drive_1) r2139.3
● (TM31) p4048.0 = 1 = inverted
