固定式升降平臺(tái)起動(dòng)時(shí)一升速就跳閘，這是過(guò)電流非常嚴(yán)重的表象，首要檢查工作機(jī)械是不是有卡住表象，負(fù)載側(cè)是不是短路，變頻器功率模塊是不是損壞，電動(dòng)機(jī)的起動(dòng)轉(zhuǎn)矩是不是過(guò)小，拖動(dòng)不起來(lái)。
Fixed lifting platform when starting a speed up on the trip, this is the current very serious phenomenon, the primary inspection machine is not stuck phenomenon, load side is not short circuit, inverter power module is not damaged, starting torque of the motor is not too small, do not drag up. 

固定式升降平臺(tái)運(yùn)動(dòng)期間跳閘，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(guò)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.
