Yes Dave the problem is in the motor drive. This machine uses a 1000W
servo motor but the board is only capable of putting out 500 W max.

At low speed and in the tapping mode you can stop the spindle with
your hand.
I test ran one of the first ones into the UK and to be honest I wasn't
impressed with the drive arrangement.
It has one speed only and relies on the board for it speed range.
There is no way a motor of this type and using the drive it does will
get a low enough speed with the torque required.

If I bought one I wouldn't bother as I'd regard it as a kit of parts,
gut the drive, fit two or three speed poly vee drive and a decent 3~
motor with VFD.
What would worry me is if I wasn't capable of this, spent my money and
expected some sort of service.
A bulk buy shortcuts any mainland service unless the organiser want's
to put his hand up for service.
Forget any factory service, they won't want to know after they have
taken money. You aren't liable to give them repeat orders like an
importer and the importers don't want to know as you are taking their
bowl of rice, - literally.
