502476L线路接口模块,502476L使用速度
双列直插式开关S2是一个八极双列直插式开关，用于设置解调器增益。如果配置了模块，则忽略该双列直插式开关具有功能代码55。将解调器增益设置为解调器增益放大反馈信号，使LVDT反馈信号的峰-峰跨度接近可实现全范围的16位分辨率模数转换器。如果模块配置为按照
使用功能代码150的IMHSS02模块，该双列直插式开关必须具有手动LVDT校准的初始设置。参考双列直插式开关S3是一个设置控制器的八极双列直插式开关
502476L线路接口模块获得如果模块配置为功能代码55。将控制器增益设置为1。
该放大器将位置需求与位置反馈进行比较并输出这些信号的差值。控制器增益影响控制回路的响应。如果使用功能代码150将模块配置为IMHSS02模块，则双列直插式开关必须具有初始设置。参见控制器在附录B中进行调谐，以初始设置手动控制器的S2增益调谐。S3双列直插式开关设置见表3-3。
Dipswitch S4 is a two-pole dipswitch that sets the LVDT oscillator frequency. This dipswitch is ignored if the module is con
figured as an IMHSS03 module using function code 55. Set all
poles to one (open).
If the module is configured as an IMHSS02 module using func
tion code 150, set the LVDT oscillator frequency to the fre
quency specified by the manufacturer. To set the LVDT
oscillator frequency:
1. Refer to the LVDT specifications for the recommended
LVDT primary excitation voltage frequency.
2. Refer to Table 3-4 for dipswitch settings and set S4 so that
the LVDT oscillator meets the manufacturer’s specifications.
Dipswitch S5 - Dither and LVDT Oscillator
Dipswitch S5 is an eight-pole dipswitch that sets the dither
oscillator frequency and amplitude, and the LVDT oscillator
amplitude (LVDT primary excitation voltage).
Set the dither oscillator amplitude and frequency to the value
the manufacturer of the servo valve recommends. Dipswitch
poles one and two set the dither oscillator frequency. Poles
three and four set the dither oscillator amplitude or disables
the dither oscillator circuitry. Poles five through eight set the
LVDT oscillator amplitude. Set the LVDT oscillator amplitude
to the value that the LVDT manufacturer recommends. To set
dipswitch S5:
1. Refer to the servo valve specifications for the recommended
dither oscillator current amplitude and frequency.
2. Refer to Table 3-5 for dipswitch settings and set poles 1
through 4 accordingly.
