Need Help!- fuse tripping on 201 @ ~30 IPM

[cyclotron]

Hi all,

I have 3 201's all wired up. 2 of them run my motors fine but the third
trips the 5 amp fuse when the velocity goes above about 30 IPM. (Thats
10,000 steps per inch with my lead screw.) I know that it's not my motors and I know I've wired everything correctly. (Wiring is identical to that of the 2 working drives...) My other drives will hit 150 IPM just fine, with both high and low acceleration.

any suggestions on whats wrong or where to start my investigation?

swap "problem" driver with one that is running 150IPM if problem follows then its the driver if problem does not follow the driver... then look at the motor, force required to move axis, etc.

i'm going to try that tonight. none of the motors are hooked up to a machine, so its not even a matter of forces. I've already determined that it is not the motors. Right now its between the drive and the wiring to the drive, so swapping it to another set of wires (same thing as swapping the drive should let me know.)

I called gecko and they suggested the same thing. I wonder what there QC practices are. In any case they said they's be happy to look over the product even though I bought it last August.
