I have a program that is using a CPT instruction to control VFD speeds , the problem I am having is a few drives will run the correct speed but it will be way out of the speed parameter on the Panelview and the others drives will not come up to the correct speed. This a program that is running running PF40 drives and I am converting the program over to PF525 drives. The expression is VFD101FPM*(60/60)*10 The VFD101FPM is panelview numeric entry from 20-100 the equation is missing a 0 but I just don't stand why one drive will work and others will not. Any help would be appreciated.
good day sir, please provide a video related when to use multiply divide and subtraction and addition in plc logic please provide pdf or provide a video related to this sir thank you sir

I've seen this instruction before, now I know I didn't really understand it. Thanks
