Hello, I am using the pmdx-126, with ess smooth stepper, and gecko 213v drives... I am not able to get the motors to operate when I am using the 26pin cable plugged into j19, and into the pmdx-133...the step and direction LED's do light when motion is commanded...ie jog. (MACH3)
Before plugging the drives into the pmdx-133, I verified the polarity of the incoming DC (50vdc), and the green LED,did light. I also, checked for continuity on all the pins of the 26 pin cable.
When I wired the signals directly from the terminal strip on the pmdx-126 to the driver terminals, it works just fine.
I am missing something....but can not see it..
