Hi All
I have just about finished my power supply and I am wanting to prove it before I go any further.
My system is using the Gecko 210, I have wired everything up as per the instructions checked and double checked.
Stepper motors are Nema 34 rated at 2.5volt @ 4.6 amp per phase, 8 wire, connected Bi-Polar parallel. The colour coding is as follows:-
Red * Winding 1
Red/White
Yellow Winding 2
Yellow/White*
Orange* Winding 3
Orange/White
Black Winding 4
Black/White*
The above is connected
Red and Yellow/White Phase A Gecko
Yellow and Red/White Phase B Gecko
Black and Orange/White Phase C Gecko
Orange and Black/White Phase D Gecko
The * denotes start of each coil, all of the stepper info was given to me by the motor supplier.
I have limited the Gecko’s to 2amp with a 18k resistor just for the trial, when I power up the supply, the 5 amp fuse which is protecting the Gecko’s blows, but if I disconnect the stepper, the fuse holds and the Gecko power light is on. The supply voltage is about 48volts just below the 20 times the motor rating as per the recommendation from Gecko.
The only thing I am not sure about is the way in which I have wired the windings to the Gecko so if one of the more knowledgeable people could help I would be most grateful.
Thanks
Andy
