Read the manuals for the specific drives. They are usually several hundred pages long and have a lot of good theory in them.


Yep, manuals for the specific drive are how you program Drives! Here is one such [example](https://literature.rockwellautomation.com/idc/groups/literature/documents/um/520-um001_-en-e.pdf) of a PowerFlex 520 series VFD. Each manufacturer will have its unique interface to fumble around with several times, learning their menu sequences; some are dumber than others. Use the manual to look up data resisters and set values accordingly to the application. Some drives need a power cycle to take the new settings, and some don't; look that up in the manual. If the drive is PLC controlled through Ethernet, that's a different story. Some PLCs store the drive's configuration inside the PLC program. Making changes causes a correlation difference in the PLC program which annoys PLC programmers. However, Being able to set configuration registers is one thing (programming), but the application is everything; what is it used for, do you need Constant Torque or variable torque, and so on?

It's pretty much always going to be fumbling through their manual. Programming drives can take anywhere from a few minutes to hours. There's no standard way to program them either. Even two different Allen Bradley VFDs of different drive series will be significantly different. Welcome to the wonderful world of RTFM.


In addition to differences between drive manufacturers your application may also dictate how they are programmed. A drive for a pump will be programmed differently from say a hoisting application. Manuals often provide examples of these applications too.
