Re: [CAD_CAM_EDM_DRO] Gecko Faults

Two things, Do you have the jumper from ERR?RES to encoder on the drive? How did you route your encoder cables in relation to the motor leads? If they are in the same seal-tite enclosure etc. they will cross talk and fault the drive. The motor leads and encoder leads are like long antennas. Even if the encoder leads are sheilded it doesnt matter they have to be seperated. Encoder + and - must be sheilded from the encoder A and B channels as well. A ground from the machine control to machine also. Just a few things to check.

Direct drive. I got some off of ebay. I bought these motors

hooked up, I have the accel/velocity turned way down. They fault
almost immediately. Is there something I am doing wrong, or these
motors just not up the the job at hand? Thanks
