Re: Quick RF-45/VFD question

Hi Drew,

I have a single phase, one motor speed RF-45 without power down-
feed and it does not have any kind of spindle brake. Don't know about
any of the other versions, but I never read anything in any of the
catalog specs for any version that said anything about a brake.
