4.7 Proportional Gain and Damping Settings (for Smoothness and Sensitivity).
Select Setup Mode, and the first parameter selected is automatically PGAIN – Proportional Gain. Press the SET push button, and the PGAIN LED will start blinking. The value of the parameter can now be increased or decreased by pressing the UP or
DOWN push buttons as required. There are twenty nine (29) PGAIN settings which can be selected, the setting altering by a factor of about 1.1 each time the UP or DOWN button is pressed. The default setting lies in the middle of the range, giving fourteen settings above and fourteen below. Any button presses beyond the last (fourteenth) will have no effect.

Note: As soon as the UP or DOWN push button is pressed, the new PGAIN value is stored in non-volatile memory and is retained even if the positioner is de-energised before leaving Adjust and Setup Modes.

The positioner is active while adjusting the PGAIN setting, and continues to follow the input signal. This gives the opportunity to change the input signal in a manner typical of the application, and to observe qualitatively the response of the positioner, and how it has been affected by changing the PGAIN setting, so as to optimise the response. Pressing the UP button maximizes the sensitivity and accuracy, at the cost of increased jerkiness of response when the signal is ramped smoothly, and if you go too far this increases the proportional gain so much that the positioner becomes unstable and hunts around the position set by the signal. Pressing the DOWN button maximises smoothness during ramping of the signal, at the cost of losing rapidity of response to small changes in signal. When the right setting has been found, press the SET button again to leave Adjust Mode
–   the PGAIN LED will now light continuously.

The DAMP (damping) parameter should be set after the PGAIN has been optimised. In Setup Mode select the DAMP parameter (second up from PGAIN) by pressing the UP button until the DAMP LED lights continuously. Press the SET button to select Adjust Mode, and the DAMP LED will blink. Damping can be increased and decreased by pressing the UP or DOWN buttons. There are twenty nine damping settings which can be selected, the setting altering by a factor of 1.1 each time the UP or DOWN pushbutton is pressed. The default setting lies in the middle of the range, giving fourteen settings above and fourteen below. Any button presses beyond the last (fourteenth) setting will have no effect. 数字式EL定位器英文文献和中文翻译:http://www.751com.cn/fanyi/lunwen_9012.html
