REXROTH放大器RA系列特點
模擬放大器最多可激活兩個比例電磁閥。規(guī)定的控制電壓在放大器中作為輸入變量進行處理。模擬放大器提供調(diào)節(jié)電流作為輸出變量，以驅(qū)動比例電磁閥。
比例螺線管的放大器輸出通過一個死區(qū)來激活。輸入端最大設(shè)定點電壓的5％，即最小輸出電流被施加?？梢允褂梦⒄{(diào)電位器分別為兩個比例輸出分別調(diào)整此最小輸出電流的水平。如果輸入上的設(shè)定值電壓增加，則每個比例電磁閥的輸出電流都會線性增加。
最大輸出電流也可以使用微調(diào)電位器分別調(diào)節(jié)。輸出曲線的斜率受此影響。
模擬放大器包含時間斜坡功能，可用于調(diào)節(jié)輸出電流可以匹配修改后的設(shè)定值的時間段。斜坡時間調(diào)整范圍從100ms擴展到10s?？梢允褂梦⒄{(diào)電位器為每個螺線管調(diào)節(jié)時間斜坡功能。
The analog amplifier activates up to two proportional solenoids. The specified control voltage is processed in the amplifier as an input variable. The analog amplifier provides a regulated electric current as an output variable for actuation of proportional solenoids.
Amplifier outputs for proportional solenoids are activated through a deadband of approx. 5% of the maximum setpoint voltage at the input, i.e. the minimum output current is applied. The level of this minimum output current can be adjusted separately for both proportional outputs using a trimming potentiometer. If the setpoint voltage at the input is increased, the output current for each respective proportional solenoid increases linearly.
The maximum output current can also be separately adjusted using a trimming potentiometer for the outputs. The gradient of the output curve is influenced by this.
The analog amplifier contains time ramp functions which can be used to adjust the period in which the output current can be adapted to match a modified setpoint. The ramp time adjustment range extends from 100 ms to 10 s. The time ramp functions can be adjusted using trimming potentiometers for each solenoid.
