This is the first time I've had the pleasure of setting one of these up.
It's a little 1.5kw, 3p 400v one running a centrifugal fan, 1.1kw motor.
It's speed reference is via 0-10v Analogue Input, which is coming in nice and steady, however the drive output is not steady at all.
It will fluctuate for around 90s, +- 5% around the desired SP, but will settle down eventually, until the speed is changed again.
The drive is set up with all the correct motor parameters, I've done AMT as well, so I'm at a loss.
Any pointers from someone familiar with Danfoss shine a light?
What would of took me 10 minutes with a PF525 or a V20, has so far consumed today, well until 2pm until I went home!
