3、 起動
3.1給出“接通”指令后，若電機不轉(zhuǎn)，3G3FV-PFS4874-400-99請先檢查一下變頻器，是否設(shè)定了輸出頻率；加減速時間設(shè)定的是否恰當(dāng)；V/f模式選擇的是否合適；3G3FV-PFS4874-400-99電子熱保護(hù)的給定標(biāo)度是否正確等。若電動機還不轉(zhuǎn)，請再檢查電機的接線和負(fù)載情況。
3.2電動機起動后，立即起動風(fēng)機（對IC416冷卻方式），并注意觀察電機、傳動裝置、生產(chǎn)機械及變頻器面板的顯示數(shù)據(jù)，若有異常現(xiàn)象應(yīng)立即停機，查明故障并排除之后，方可重新啟動。
4、 正常運行中的維護(hù)
   3G3FV-PFS4874-400-99用變頻器對電動機進(jìn)行調(diào)速運轉(zhuǎn)，由于變頻器輸出波形中含有的高次諧波的影響，電動機噪音及振動比電網(wǎng)供電時的略大是正常的。隨著運轉(zhuǎn)頻率的變化，基波分量、高次諧波分量在廣范圍內(nèi)變化，與電機各部分及機械負(fù)載的諧振現(xiàn)象也增加，在調(diào)速到與系統(tǒng)諧振頻率相一致的點時，機械系統(tǒng)將有大的振動和噪音。產(chǎn)生這種現(xiàn)象時，可采用增強系統(tǒng)剛度的方法來避免諧振，也可利用變頻器的頻率跳變功能，使與諧振點相當(dāng)?shù)妮敵鲱l率向上或向下跳變，避開諧振頻率，實現(xiàn)平滑運轉(zhuǎn)。
