In your opinion, as a vfd customer or supporter or user, what do you think is the most robust vfd.
I heard of that. then i recommended them to my customer, then they failed. still trying to heal from that black eye. next?Yaskawa nothing else comes close
They are about 5 years ahead of the closest competition
switching 4 and 40 to smaller 750 series.
I've used Powerflex 40 once and can't remember anything about it but from the reviews here I just may give it a try or at least get a price for one and see how things go.
Go with the 523 or 525 drive. They are the newer replacement of the 40 series and come with a few more features for a lower price. The major different between the 523 and 525 is the Powerflex 525 has ethernet communication and safe torque off options included. If you don't need either of those, you can save a few bucks getting the 523 model.
