sir actually i want only hint .... i know how to make ladder diagram , i make so many program .i have a analog module in my plc   but now  i want help from you people ...which is like that  how to change frequency of the VFD (allen bradley powerflex 4m) from analog output module of PLC (rslogix 1500 Allen bradley ) by change analog input terminal of plc 

actually till now i am changing my analog output voltage by   change of analog input ....but  now i want to know how i change frequency of VFD by proportion of change of analog input of plc 

how to make a  ladder logic for  speed control of induction motor using VFD powerflex4m 

i need a program to control a speed of a Induction motor by change the frequency ... in the VFD 

kindly send me a ladder logic diagram on 1500 rslogix AB ,.. i m student in college this is my project work in vacation
