1794-ASB模塊,1794-ASB使用數(shù)量
雙列直插式開關(guān)S2是一個八極雙列直插式開關(guān)，用于設(shè)置解調(diào)器增益。如果配置了模塊，則忽略該雙列直插式開關(guān)具有功能代碼55。將解調(diào)器增益設(shè)置為解調(diào)器增益放大反饋信號，使LVDT反饋信號的峰-峰跨度接近可實(shí)現(xiàn)全范圍的16位分辨率模數(shù)轉(zhuǎn)換器。
1794-ASB模塊如果模塊配置為按照使用功能代碼150的IMHSS02模塊，該雙列直插式開關(guān)必須具有手動LVDT校準(zhǔn)的初始設(shè)置。參考雙列直插式開關(guān)S3是一個設(shè)置控制器的八極雙列直插式開關(guān)獲得如果模塊配置為功能代碼55。將控制器增益設(shè)置為1。
該放大器將位置需求與位置反饋進(jìn)行比較并輸出這些信號的差值。控制器增益影響控制回路的響應(yīng)。如果使用功能代碼150將模塊配置為IMHSS02模塊，則雙列直插式開關(guān)必須具有初始設(shè)置。參見控制器在附錄B中進(jìn)行調(diào)諧，以初始設(shè)置手動控制器的S2
增益調(diào)諧。S3雙列直插式開關(guān)設(shè)置見表3-3。
Dipswitch S2 is an eight-pole dipswitch that sets the demodulator gain. This dipswitch is ignored if the module is configured
with function code 55. Set the demodulator gain to a value of
two.
The demodulator gain amplifies the feedback signal so that the
peak-to-peak span of the LVDT feedback signal is as close as
possible to the full range of the 16-bit resolution analog-to-digital (A/D) converter. If the module is configured to operate as
an IMHSS02 module using function code 150, this dipswitch
must have an initial setting for manual LVDT calibration. ReferDipswitch S3 is an eight-pole dipswitch that sets the controller
gain. This dipswitch is ignored if the module is configured with
function code 55. Set the controller gain to one.
This amplifier compares position demand to position feedback
and outputs the difference of those signals. The controller gain
affects the response of the control loop. If the module is configured as an IMHSS02 module using function code 150, this
dipswitch must have an initial setting. Refer to CONTROLLER
TUNING in Appendix B to initially set S2 for manual controller
gain tuning. Refer to Table 3-3 for S3 dipswitch settings.
