2364-SPM03A數(shù)控模塊,2364-SPM03A怎么使用
要開始控制器調(diào)諧，MFP模塊必須與IMHSS03模塊通信，并滿足以下條件
必須滿足：?控制器增益必須設(shè)置為1。?解調(diào)器增益調(diào)諧必須完成。?渦輪機(jī)離線。?伺服閥或I/H轉(zhuǎn)換器（用于渦輪機(jī)液壓系統(tǒng)）必須處于控制位置并正常工作
正確地?多功能處理器模塊的功能代碼為55在其配置中。
?包含校準(zhǔn)模式啟用規(guī)范的塊設(shè)置為禁用（S11=0）。手動(dòng)調(diào)整控制器增益：
2364-SPM03A數(shù)控模塊1.使用方框輸入位置要求（S6中規(guī)定）包含位置需求百分比。輸入50%的值，75%和90%。觀察閥門在每個(gè)位置的響應(yīng)需求水平。閥門應(yīng)在以下條件下響應(yīng)而不振蕩：各級(jí)需求。
2、如果閥門在所有需求水平下運(yùn)行平穩(wěn)，則將控制器增益增加到下一個(gè)更高的值并重復(fù)步驟1和2。3、當(dāng)控制器增益達(dá)到閥門在任何需求水平下振蕩，將控制器增益降低至下一個(gè)較低的值。重復(fù)步驟1至3以驗(yàn)證該閥在所有需求水平下均能平穩(wěn)運(yùn)行。這是校正控制器增益。
To start controller tuning, the MFP module must be communi
cating with the IMHSS03 module and the following conditions
must be met:
?
The controller gain must be set to one.
?
Demodulator gain tuning must be complete.
?
The turbine is off-line.
?
The servo valve or I/H converter (for turbine hydraulic sys
tem) must be in the controlling position and functioning
properly.
?
The multi-function processor module has function code 55
in its configuration.
?
The block containing the calibrate mode enable specifica
tion is set to disable (S11 = 0).
To manually tune the controller gain:
1. Enter position demands using the block (specified in S6)
containing the percent position demand. Enter values of 50%,
75%, and 90%. Observe the response of the valve at each
demand level. The valve should respond without oscillating at
each level of demand.
2. If the valve operates smoothly at all demand levels, then
increase the controller gain to the next higher value and repeat
Steps 1 and 2.
3. When the controller gain reaches a point where the valve
oscillates at any demand level, decrease the controller gain to
the next lower value. Repeat Steps 1 through 3 to verify that
the valve operates smoothly at all demand levels. This is the
correct controller gain.
