LS PLC Analog I/O

[sifat 1]

Hi! I m new in this forum. So please forgive my any silly mistake. I want to know about the analog programming function of LS PLC. I do know about the progrmming instruction (MOV,ADD,SUB,MUL,INCP,Analog Data register (D4980-D4983 for 4 channel ) etc). I also know about the scaling like , for voltage (0-10V is for digital data bit 0-4000) Infact, i want to control motor speed which is usually run by Toshiba inverter. I wanna control it's speed by increasing and decreasing voltage by push button. Could i get any ladder example. I hope it will be very much helpful for me. Please help. My PLC type is MASTER K80S and software is KGL_WIN.
