未能校準(zhǔn)并在那里沒有配置或安裝錯(cuò)誤。
過程硬件檢查過程硬件。LVDT校準(zhǔn)失敗。
LVDT 100%無電壓比LVDT 0%電壓檢查LVDT連接。更換LVDT。
無法調(diào)諧解調(diào)器增益。主振蕩幅度。調(diào)整主振蕩器的振幅。
YOKOGAWA CP451-10處理器模塊無伺服驅(qū)動伺服放大器。連接不良至伺服閥門，有缺陷伺服閥。檢查伺服閥。
1.在適當(dāng)?shù)奈恢脤⑹静ㄆ鬟B接到伺服閥終端裝置或模塊端子（SERVO_C_）。連接
示波器探頭在伺服輸出。通過執(zhí)行步驟2檢查伺服輸出到4。對每個(gè)不良的伺服輸出重復(fù)該步驟。2.輸入位置需求以更改執(zhí)行器位置。3.驗(yàn)證每個(gè)伺服都有伺服驅(qū)動和返回信號輸出
4、如果沒有伺服閥驅(qū)動信號或返回信號，檢查連接電纜的連續(xù)性。

Check the process hardware.
LVDT calibration
fails.
LVDT 100%
voltage less
than LVDT 0%
voltage.
Check LVDT connection. Replace LVDT.
Cannot tune
demodulator gain.
Primary oscilla
tor amplitude.
Adjust amplitude of primary oscillator.
No servo drive from
the servo amplifiers.
Bad connection
to the servo
valve, defective
servo valve.
Check the servo valve.
1. Connect an oscilloscope to the servo valve at the appropriate
termination unit or module terminals (SERVO_C_). Connect the
oscilloscope probes differentially across the + and – terminals of
the servo output. Check the servo outputs by doing Steps 2
through 4. Repeat the procedure for each bad servo output.
2. Enter a position demand to change the actuator position.
3. Verify that there is a servo drive and return signal for each servo
output.
4. If there is no servo valve drive signal or return signal, check the
continuity of the connecting cables.
