MVME143變頻器在參數中設定電機的功率、電流、電壓、轉速、大頻率，這些參數可以從電機銘牌中直接得到。
跳頻
在某個頻率點上，有可能會發生共振現象，特別在整個裝置比較高時； 在控制壓縮機時，要避免壓縮機的喘振點。
加減速時間
加速時間就是輸出頻率從0上升到大頻率所需時間，減速時間是指從大頻率下降到0所需時間。 通常用頻率設定信號上升、下降來確定加減速時間。 在電動機加速時須限制頻率設定的上升率以防止過電流，減速時則限制下降率以防止過電壓。
加速時間設定要求：將加速電流限制在變頻器過電流容量以下，不使過流失速而引起變頻器跳閘； 減速時間設定要點是：防止平滑電路電壓過大，不使再生過壓失速而使變頻器跳閘。 加減速時間可根據負載計算出來，但在調試中常採取按負載和經驗先設定較長加減速時間，通過起、停電動機觀察有無過電流、過電壓報警； 然後將加減速設定時間逐漸縮短，以運轉中不發生報警為原則，重復操作幾次，便可確定出佳加減速時間。
