After removing the GND line from the ICM2900 to my +/- 10v reference signal at the servo motor, the motor only goes one direction.
My servo drive takes a +/- 10V signal with inputs marked as "inverted" , "NonInverted", "0 volts".
The IMC2900 gives me McmdX and Gnd.
If I hook it up the way I used to have it, I get oscillations in the motor. (Noise?).
I have tried to shield the +/- 10v signal cable at one end, then the other, then both. Nothing makes a difference.
Why oh why did this thing work perfectly 2 months ago and now is giving me so many problems.
Thanks for all the help
