Overload capability
Sinamics S120底盘单元具有超载储备，例如至
handle breakaway torques. If larger surge loads occur, this must
be taken into account in the configuration. For drives with over-
load requirements, the appropriate base load current must,
因此，用作所需负载的基础。
允许的过载水平在先决条件下有效
驱动器单元以其基本负载电流运行
根据占空比的过载条件之前和之后
持续时间为300 s。
对于临时的，周期性的占用周期，负载变化很大
within the duty cycle, the relevant sections of the SINAMICS Low
Voltage Engineering Manual must be observed.
