The question in general is:
When using a PPR to provide feedback to a VFD, is there a maximum value above which higher PPR can actually hurt?
I understand that a higher frequency signal may be more prone to error than a lower frequency signal, so that is one aspect to consider. In this...
I've got an older speed reducer with a mounting flange sized for a 184C DC motor. I'm looking to convert this machine to AC control with a VFD + encoder, but it doesn't appear this is a common motor size. I've identified a 145TC motor that would work well for the application... is there a...
So it has been a few years since I've had to specify a VFD, and have been doing some homework to make sure I am up to date with the current technology. It seems that there is a new (to me) class of vector algorithm that has achieved better performance than what I think of as open loop vector...
