VFD programming Hz ?

[slow-poke]

Small sample, but I have had great success buying used on ebay from the second group. Usually pay about $100 or less shipped.

I purchased two new from the first group, and one failed within a year with little use, the second is okay so far, but really does not get a lot of use, if it fails I will never buy a group one again.

I would avoid anything without:
+ flux vector control mode
+ external braking resistor

Most guys are way better off looking for a reputable brand used off eBay.

For example:

Yaskawa VFD CIMR-VU4A0005FAA 3HP 5.9A V1000 AC Drive | eBay

Find many great new & used options and get the best deals for Yaskawa VFD CIMR-VU4A0005FAA 3HP 5.9A V1000 AC Drive at the best online prices at eBay! Free shipping for many products!

www.ebay.ca

That one would be an awesome drive for someone.

Yaskawa has on their website under the v1000 model: failure rate 1 in 10,000.

Mtbf: (mean time before failure) 28 YEARS.

A similar drive from Mitsubishi has a 5 year warranty….. they post average lifespan with normal use (example of normal use: running in a factory 24/7) for their machine drives: 10 years.

Amazon drive vs Japanese name brand drive, or most other name brand drives is apples and oranges.

The Japanese drives are typically bears to program though…. European/American companies (Teco/Schneider/Vacon)usually have an easier user interface…. But almost always less warranty.
