對(duì)于大容量的電機(jī)，若設(shè)置加速時(shí)間太短，可能會(huì)使變頻器過流跳閘；設(shè)置減速時(shí)間太短，可能會(huì)使變頻器過壓跳閘。對(duì)于多電機(jī)同步運(yùn)行的情況，若設(shè)置加速時(shí)間太短，可能會(huì)使變頻器過流跳閘，設(shè)置加速時(shí)間太長(zhǎng)，會(huì)使開車 時(shí)同步性能變壞；設(shè)置減速時(shí)間太短，可能會(huì)使變頻器過壓跳閘，設(shè)置減速時(shí)間太長(zhǎng)，由于各電機(jī)功率不同，負(fù)載差異較大，可能會(huì)使各電機(jī)不能同時(shí)停轉(zhuǎn)，造成下次開車?yán)щy。

因此，多電機(jī)同步運(yùn)行時(shí)，需要設(shè)置加、減速時(shí)間，這也是設(shè)備調(diào)試的主要項(xiàng)目之一。

3、保存配置drC（或I-O、CtL、FUn）—SCS

對(duì)于經(jīng)常使用的設(shè)置或經(jīng)現(xiàn)場(chǎng)調(diào)試可行的設(shè)置，可以保存起來，在需要的時(shí)候可以恢復(fù)。但保存配置只能保存一次，再次保存時(shí)，原來保存的設(shè)置就被新保存的設(shè)置所替代。
