No sorry the control box is built but the mill it is going on will take some time. I purchased the above because am882's are getting hard to find.

Hi Clive S,


I have been researching some more.

Do the spec of stepper memtion rms or peak amps? Looks like the 2dm856 driver is rated 4 amp rms ...... 5.5 peak.

Are those rms values?
Ill send an email to cnc4you and find out.

Grtz. Bert.

They are Peak ratings, most motor ratings if data sheet doesn't show both will be the peak rating.

Also, I have some of the 2DM860H but only tested on the bench at the minute. however, they seem nice smooth with low motor heating even after being stood for hours. This is always a good sign because lose motor sat on bench is open to resonance and the drive is obviously handling any resonance because nice smooth operation.
Will tell better when put on a machine but so far I wouldn't tell the difference between these and AM882.

Awesome! Awaiting your final judgement since I have those drivers :)
Have you altered any settings via software or only dip switches?
