The following characteristic is set by default and can be adapted to the application viathe parameters mentioned.Ypos. maximum value( X2 / Y2 )Point 1:X1 = 2.00% ⋅10 V = 0.20 VY1 = 0.00% ⋅50.00 Hz = 0.00 Hz0V(0mA)( X1 / Y1 )+10V X(+20mA)Point 2:X2 = 98.00% ⋅10 V = 9.80 VY2 = 100.00% ⋅50.00 Hz = 50.00 Hzneg. maximum valueThe freely configurable characteristic enables setting a tolerance at the ends as wellas a reversal of the direction of rotation.The following example shows the inverse reference value specification with additionalreversal of the direction of rotation. This is often used in pressure control systems.Ypos. maximum value100%Point 1:( X1 / Y1 )X1 = 2.00% ⋅10 V = 0.20 VY1 = 100.00% ⋅50.00 Hz = 50.00 Hz0V(0mA)-80%( X2 / Y2 )+10V(+20mA)XPoint 2:X2 = 98.00% ⋅10 V = 9.80 VY2 = −80.00%⋅50.00 Hz = −40.00 HzThe reversal of the direction of rotation iseffected in this example at an analoginput signal of 5.5V.The definition of the analog input characteristic can be calculated via the two-pointform of the line equation. The speed Y of the drive is controlled according to the analogcontrol signal X.Y2 - Y1Y = ⋅ +X2 - X1( X − X1) Y102/06 117
