YOKOGAWA CP451-10处理器模块,CP451-10说明书在线阅读
未能校准并在那里没有配置或安装错误。
过程硬件检查过程硬件。LVDT校准失败。
LVDT 100%无电压比LVDT 0%电压检查LVDT连接。更换LVDT。
无法调谐解调器增益。主振荡幅度。调整主振荡器的振幅。
YOKOGAWA CP451-10处理器模块无伺服驱动伺服放大器。连接不良至伺服阀门，有缺陷伺服阀。检查伺服阀。
1.在适当的位置将示波器连接到伺服阀终端装置或模块端子（SERVO_C_）。连接
示波器探头在伺服输出。通过执行步骤2检查伺服输出到4。对每个不良的伺服输出重复该步骤。2.输入位置需求以更改执行器位置。3.验证每个伺服都有伺服驱动和返回信号输出
4、如果没有伺服阀驱动信号或返回信号，检查连接电缆的连续性。

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.
