How to use incremental rotary encoder to move a three phase induction motor
asjeetabhi8816 replied to asjeetabhi8816's topic in Allen Bradley / Rockwell Automation
I am using Micrologix 1400 PLC which has 6 HSC Counter inputs. Actually i have to move an object to different positions with the help of Induction Motor. Right Now it is controlled by PLC (Using Contactors) just to move motor forward and reverse. But i have to specify certain 4-5 buttons which will take that object to different positions (which i will set with the help of encoder).But i am confused which instruction i should use to move that object to different positions. -

I have tried COP command again and this time its working. But i have one problem, when i scan a certain value at ST 12:1 (as an example),then the value gets copied to ST 12:20(through COP command).But when i reset the scan and scan again the value do not remain on ST 12:20.It gets vanished. So can you tell me how to save that value so that i can compare it with another scan -

Thanks for the reply b_carlton But how to use this copy command in case of string? I have put ST12:1 to source and ST12:2 to destination with 10 as length.but it is saying my program has errors. So can you tell me how to put values of string in COP command. -
