What's causing it I've no idea and I can't read that manual very well because the pictures are crap.!
Ah, right, my ignorance. I think my settings spin up in about 1/2 that on the Chinese spindle, less on the servo - probably silly amount of energy being hit into the respective motors - I might look to reduce that. 2 or 3 seconds isn't ever going to save the world but it's likely to improve the life of the VFD.

The photos were a struggle. But not as much as the poor manual.
