Re: G-320 Servo current setup

Good afternoon Mariss,

3.6A should be fine. I just need 2.0A for now. I was surprised to see
a parallel and a series current column. I will use 1/2 winding, which
the Centent manual calls parallel. That's 68K. Which would be 4.0A for
series? That's a bit of a surprise to me. Not so on Gecko's (right?).

The Centent manual also says "The CN0142 is designed to run unipolar
hybrid PM step motors with current ratings from .75 to 7A per phase;"
The cover clearly shows a bipolar (4 wire) connection, however later
connection diagrams in the manual also indicate a bipolar connection.
:>)

Next to see if I can fit four on one of my heatsinks!

Kinda hard to peek inside! ;>)

Thanks for the information

Alan KM6VV

Lots of good information in the manual!
