Re: Seaking information Compumotor M83-135 Stepper Motors

First of all thanks for replying. I will be using Driver modules
from Compumotor. They are the C Series models. They work similar to
the Geckos, voltage supported is 12 -90v, Up to 5a per phase.
Resolution steps from 200 up to 25,000 can be set. It does require
two seperate voltages. The one mentioned for the motors and a second
for the logic. Logic requires a minimum of 9 to 24v regulated.
Standard indexer connection information is:Pins 1 and 14 control
Step + and -, Pins 2 and 15 control direction + and -, and Pins 16
and 17 control shutdown + and -. I plan to use a parallel port unit
and use the Step +(Pin 1), Direction + (pin 2) connections and
ground Pins 14 and 15. I will leave the shutdown floating I believe
or ground it ( Not sure yet). I'm open to comments or redirection.
But still need to build the power supply. From reading your info I
should go with a 75-90v Power supply with 5or mor amps. I guess one
question comes to mind. Will it damage the motors to use higher
voltages? Then again I guess as long as the Driver supports it, then
it should be fine right? What about the amps. Should I go for more
than 5 amps. Again what about damage? The driver limits at 5 amps
per phase. Or is the combined need of all three drivers dictates the
need for more than 5 amps. I know I will get this sooner or later.
Just don't want to fry my hardware.

Appricate the help fellas!


Cheers,

Shawn
