VFD data sheet
VFD data sheet
(OP)
Hi all!
Can someone tell me what are MINIMUM NECESSARY data for valid VFD data sheet? I'm writing it for the first time and I'm not sure. 250kW motor, centrifugal pump for water intake. Besides nominal motor power/current, is it necessary to specify starting current, maximum torque and speed range? Why is important to specify lower speed limit? I suppose it isn't related to soft start function and the latter is default. Anything else that I should know?

We cannot tell you without more details then you probably know yourself. I would highly recommend you hire someone to spec out the VFD for you. Then you can shop that spec around.
There are probably 30 things you should have down on that sheet.
Further more there are things like service and support which should weigh in on this too. I would hire someone myself for one that big even though I've probably bought 25 VFDs.
You can contact me and I will try to connect you with someone if you can't hunt someone down locally. Where are you located?

Keep in mind by the way that VFD is also used for Vacuum Fluorescent Display, so be careful.

Are you writing a spec for somebody to supply you with a VFD or writing a spec to sell a VFD?
