介绍了同步应用的操作，并展示RSYC 同步单元的接线图和外形图。
RSYC 同步单元主要用于与装有标准应用程序的ACS800 变频器配合（也可用于ACS510/550），在较弱电网中启动大功率电机，从变频工作切换至工频的无冲击软启动切换控制过程。变频器平滑地启动电机，同时产生大转矩，没有工频直起的大电流。当达到额定频率时，RSYC 检查供电电网与变频器输出的电压相位，并且快速调整变频器输出电压的相位与电网一致，控制接触器将电机从变频器输出侧切换至电网。 为传动选择合适的 du/dt 滤波器提供了建议。

IGBT 传动单元会对电机端子产生比中间直流回路电压高很多的尖峰输出电压。这个
具有很大 du/dt 值的尖峰电压会对电机和电机电缆绝缘带来额外的压力。这将会缩短电机的寿命。 ABB 的 可选件 du/dt 滤波器可以保护电机的绝缘系统。

system structure
The Freelance 800F process control system is divided into operator levels
and process control level. The operator level contains controls for operation and display.
Archiving and logging, trending and alarming functions. Controller executes open loop
and closed loop control function.
