The sum of the fixed and variablevalues (labelled Y in Illustration 3.7) ismultiplied with the actual reference (labelledX in Illustration 3.7). This product is thenadded to the actual reference (X+X*Y/100) togive the resultant actual reference.3-18 Relative Scaling Reference ResourceOption: Function:RelativeZ=X+X*Y/100ResultingactualreferenceYX130BA059.12ZIllustration 3.7 Resultant Actual Reference[0] No function[1] Analog Input53[2] Analog Input54[7] Frequencyinput 29[8] Frequencyinput 33[11] Local busreference3.4.3 3-4* Ramp 1Configure the ramp parameter, ramping times, for each ofthe two ramps (parameter group 3-4* Ramp 1 andparameter group 3-5* Ramp 2).tacc t dec130BD379.10P 3-*2Ramp (X)DownTime (Dec)P 4-14High-limitHzReferenceP 1-23MotorfrequencyP 4-12Low limitTimeP 3-*1Ramp (X)UpTime (Acc)Illustration 3.8 Example of Ramp 13-40 Ramp 1 TypeOption: Function:Select the ramp type, depending onrequirements for acceleration/deceleration.
