Hi Ace1985
let me explain to you maybe this is can help you.
Ladder prog it's symbol like electric picture there is switch NO or NC than output at ladder is coil or timer or special fuction.
the program PLC had you studied last time it's call LIST program, at the plc software mitsubishi like GX...
first time you check program speedpot plc is there have speedpot program or not?
if it's the plc inside has program for speedpot, try set speed to 50% then check output analog plc its must be around 5 Vdc.
if ok then connect 0 V from analog output PLC to 0V terminal your DC drive and connect 10V...
