，首要檢查：升速時(shí)間是不是設(shè)定太短，需加長(zhǎng)加速時(shí)間；減速時(shí)間是不是設(shè)定太短，需加長(zhǎng)減速時(shí)間；轉(zhuǎn)矩賠償(U/F)設(shè)定太大，然后致使低頻時(shí)空載電流過大；電子熱繼電器整定不當(dāng)，動(dòng)作電流設(shè)定得太小，致使變頻器誤動(dòng)作。
 During the trip, the movement fixed lifting platform first check: speed up time is not set too short to lengthen the acceleration time and deceleration time is too short; not set, take longer deceleration time; torque compensation (U/F) set is too large, then the resulting low frequency no-load current is too large; the electronic thermal relay setting improper action current setting is too small, resulting in inverter malfunction.
