对于大容量的电机，若设置加速时间太短，可能会使变频器过流跳闸；设置减速时间太短，可能会使变频器过压跳闸。对于多电机同步运行的情况，若设置加速时间太短，可能会使变频器过流跳闸，设置加速时间太长，会使开车 时同步性能变坏；设置减速时间太短，可能会使变频器过压跳闸，设置减速时间太长，由于各电机功率不同，负载差异较大，可能会使各电机不能同时停转，造成下次开车困难。

因此，多电机同步运行时，需要设置加、减速时间，这也是设备调试的主要项目之一。

3、保存配置drC（或I-O、CtL、FUn）—SCS

对于经常使用的设置或经现场调试可行的设置，可以保存起来，在需要的时候可以恢复。但保存配置只能保存一次，再次保存时，原来保存的设置就被新保存的设置所替代。
