Hello All,
I am new to working with PLC's and am currently trying to use a PLC to control the speed of a VFD.
I am using a 1769-L32E processor with rslogix 5000. Also, I am currently trying to use the output of the analog (1769-IF4XOF2) to control the speed and use the digital output(1769-IQ6XOW4) to start and stop the VFD.
I found the raw decimal data that corresponds to 4-20 mA ( 6218 to 31086) and trying to move it to the VFD but I am having no luck. I'm having trouble understanding the concepts being applied in this communication.
Any help is greatly appreciated.
Thank you.
