Load classes
为了能够调整SINAMICS DC Master
只需尽可能地到达驱动机的负载曲线，
in addition to the individual dimensioning using the limiting
characteristics of the dynamic overload capability, these can
also be dimensioned using pre-selected load cycles that are
simple to parameterize.
Note:
SINAMICSDC MASTER does not
监控是否加载类
- 使用参数设置 - 维护。如果电源部分
permits it, the unit can operate for overload durations in excess
of those defined by the load class. This means that the driven
机械系统的机器没有保护 -
load!
The overload duration that is actually permitted for the power
问题的部分始终长于所定义的持续时间
the load class. SINAMICS DC MASTER monitors
whether the
overload duration that is actually permitted for the power section
is being maintained.
