Motion control and feedback is inverted

[crweiss]

I have an application where the motion control and feedback is opposite of what should be commanded.  I am using LabVIEW 8.2, a PCI-7344 motion card, Pacific Scientific PC833 drive & a servo motor w/resolver.  The PC833 is emulating encoder feedback to the motion card.  I've tried swapping control/feedback signals and the system becomes unstable.  Is there any settings in max/LabVIEW to inverse the control/feedback, or are there any suggestions on what to change in the wiring to get the system to operate properly?

I am going to assume that you mean that when you command a positive move, the motor goes negative, and runs away quickly.  Different drives handle changing direction differently, but to get basic control, just switch one pair of the feedback signals going to the controller.  Swap A+ and A- or B+ and B-.

Also, is the polarity of motor connections correct?
