text: <s>[INST] PF753 - can I use units other than Hz or RPM? Summary: Web handling application - I would like to set units to feet per minute (web speed)Hi, I am considering using a PowerFlex 753 drive for a web handling application. I see that parameter 300 [Speed Units] allows me to select either Hz or RPM for the units to be used for all speed related parameters. The units that I would really prefer would be my web speed in feet per minute (FPM). This equals the surface speed of my driven roll. I can use my gear ratio and roll diameter to calculate the scale factor required to convert motor RPM to web speed in FPM, but I don't see if/how I can enter this into the PF753 so that it would allow me to enter my speed setpoint in FPM and display my actual speed in FPM. If anyone can tell me if/how I can do this, I would greatly appreciate it. Thanks in advance, Paul [/INST] You don't do it to the drive specifically - you change the process screen of the HIM. http://literature.rockwellautomation.com/idc/groups/literature/documents/um/20him-um001_-en-p.pdf See page 37 of the user manual at the link above. \\n </s>
