3BHE035301R1002勵磁系統(tǒng)模塊,UNITROL 1010使用進展
有兩種方法可以確定腹板張力與負(fù)載上測得的力之間的比率單元格，通過懸掛重量或計算。
?帶懸掛重量（菜單懸掛重量）將一根繩索準(zhǔn)確地沿著腹板路徑拉緊，并施加已知重量。
應(yīng)用的已知重量模擬實際腹板張力和電子測量施加的重量對稱重傳感器產(chǎn)生的合力。
當(dāng)腹板張力（T）和相應(yīng)的測量力（FR）已知時張力電子設(shè)備計算T/FR比率，并將該值存儲為纏繞增益。
當(dāng)卷筒張力應(yīng)用于輥時，張力電子設(shè)備通過以下方式計算卷筒張力將測得的稱重傳感器上的力乘以包裹增益。
3BHE035301R1002勵磁系統(tǒng)模塊懸掛重量程序完成后，張力電子設(shè)備計算的包裹增益可以可在EnterWrapGain菜單中找到。按計算（菜單輸入Wrapgain）
包裹增益是一個比例因子，對應(yīng)于腹板張力（T）和作用在稱重傳感器測量中的腹板張力的分力（FR）方向
包裹增益范圍為0.5-20。如果嘗試將包裹增益設(shè)置在此范圍之外，則顯示屏上將顯示消息“WrapGainTooLow”或“WrapGainTooHigh”。
包裹增益可設(shè)置為分辨率0.01。
描述纏繞增益計算原理的示例：可以設(shè)置以下參數(shù)：?過濾器設(shè)置）
?高壓（N、kN、kg、lbs、N/m、kN/m、kg/m、pli），（出廠默認(rèn)值=2000 N）
?高輸出（出廠默認(rèn)值=+10 V）
?低張力（N、kN、kg、lbs、N/m、kN/m、kg/m、pli），（出廠默認(rèn)值=0 N）
?低輸出（出廠默認(rèn)值=0 V）
?上限，（出廠默認(rèn)值=+11 V）
?如果電壓輸出信號過快或為了補償滾動不平衡，可使用下限（出廠默認(rèn)值=-5 V）濾波。
濾波器為線性相位型，最大平坦，20 dB/十年。
There are two ways to find out the ratio between web tension and measured force on the load
cells, by Hanging weights or by Calculation.
? With hanging weights (Menu HangWeight)
String a rope that follows the web path exactly and apply a known weight.
The applied known weight simulates the actual web tension and the electronics measures
the resulting force on the load cells caused by the applied weight.
When both web tension (T) and the corresponding measured force (FR) are known the
tension electronics calculates the ratio T / FR and stores the value as Wrap Gain.
When web tension is applied to the roll the tension electronics calculates web tension by
multiplying the measured force on the load cells with the Wrap Gain.
After the hanging weight procedure the wrap gain calculated by the tension electronics can
be found in the EnterWrapGain menu.By calculation (Menu EnterWrapGain)
Wrap Gain is a scaling factor which corresponds to the ratio between Web Tension (T) and
the force component (FR) from web tension that is acting in the load cell measuring
direction.
The Wrap Gain range is 0.5 - 20. If you try to set the wrap gain outside this range, the
message “WrapGainTooLow” or “WrapGainTooHigh” will be shown on the display.
The wrap gain can be set with a resolution of 0.01.
