通用型變頻器加減速時(shí)間參數(shù)設(shè)置步驟

 

邦瑞通用型變頻器加減速時(shí)間參數(shù)設(shè)置步驟。下面我們就永邦生產(chǎn)的通用型變頻器如何進(jìn)行加減速時(shí)間參數(shù)設(shè)置進(jìn)行詳細(xì)說明

變頻器加速時(shí)間就是輸出頻率從0上升到最大頻率所需時(shí)間，減速時(shí)間是指從最大頻率下降到0所需時(shí)間。通常變頻器用頻率設(shè)定信號(hào)上升、下降來確定加減速時(shí)間。在電動(dòng)機(jī)加速時(shí)須限制頻率設(shè)定的上升率以防止過電流，減速時(shí)則限制下降率以防止過電壓。

通用型變頻器加減速時(shí)間參數(shù)設(shè)置步驟

通用型變頻器加速時(shí)間設(shè)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。

通用型變頻器減速時(shí)間設(shè)定要點(diǎn)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。通用型變頻器加減速時(shí)間可根據(jù)負(fù)載計(jì)算出來，但在調(diào)試中常采取按負(fù)載和經(jīng)驗(yàn)先設(shè)定較長加減速時(shí)間，通過起、停電動(dòng)機(jī)觀察有無過電流、過電壓報(bào)警；然后將加減速設(shè)定時(shí)間逐漸縮短，以運(yùn)轉(zhuǎn)中不發(fā)生報(bào)警為原則，重復(fù)操作幾次，便可確定出最佳加減速時(shí)間。

Steps for setting acceleration and deceleration time parameters of universal frequency converter

 

 

 

Steps for setting acceleration and deceleration time parameters of bongrui universal frequency converter. Below we on yongbang production of general inverter how to speed up and speed down the time parameter Settings for a detailed description

 

The acceleration time of frequency converter is the time needed for the output frequency to rise from 0 to the maximum frequency, and the deceleration time is the time needed for the decrease from the maximum frequency to 0. Usually frequency converter set signal rise, fall to determine acceleration and deceleration time. In the case of motor acceleration, the rise rate set by the frequency should be limited to prevent overcurrent, while in the case of deceleration, the fall rate should be limited to prevent overvoltage.

 

Steps for setting acceleration and deceleration time parameters of universal frequency converter

 

General frequency converter acceleration time setting requirements: the acceleration current is limited to the frequency converter overcurrent capacity, not to cause the frequency converter tripping.

 

Steps for setting acceleration and deceleration time parameters of universal frequency converter

 

The key points of setting the deceleration time of universal frequency converter are: to prevent the smooth circuit voltage from being too high, and not to make the regenerative overvoltage stall and make the frequency converter trip. The acceleration and deceleration time of general frequency converter can be calculated according to the load, but in the debugging, it is often adopted to set a long acceleration and deceleration time according to the load and experience, and observe whether there is over-current and over-voltage alarm through the starting and power failure motive. Then, the acceleration and deceleration setting time is gradually shortened, and the optimal acceleration and deceleration time can be determined by repeating the operation for several times in accordance with the principle that no alarm occurs in the operation.
