Hi Clive S,
Do you think the leadshine dm856 will do for my setup?
http://www.leadshine.com/productdeta...DM&model=DM856
Or will i gain lots in buying am822 drives.
I am not sure i can still buy them oem ... Though somebody said there is nothing wrong with a good copy.
They look alright @80v /5.6 amps
I have the cnc4you 4amp 4nm nema23 steppers.
Grtz. Bert

I have no experience of them but they look OK I see they only go up to about 5.6A might be getting a bit close!!
I have purchase three of these:-

Hi Clive S,
I am unsure what using 4 out of 5.5 amps will do to the drives life time.
25% headroom sounds ok.
I do like the idea of having an alarm ouput also.
Do you have any idea on when you have the drives up and running?
Grtz. Bert.

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.
https://cnc4you.co.uk/resources/Step...1-03%204Nm.pdf
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.

Ok so answer of CNC4YOU... it is peak.. 3 amps RMS.
I guess ill order the leadshine dm856 then.
Save a few bucks to spend on some other things.
Grtz Bert.
Now i have to find some other way to hook up a big flashing red alarm light.
