Target Joint Angle Sign Mismatch from Virtual to Physical (Motoman)

#1
Robot Paramaters 10-24-24.JPG   
Hello,
Thanks for the great software. 
I am having an issue with the value of a target joint angle changing from the virtual to the physical robot. I am using the Motoman Post Processor, MH-50. I have corrected the 'sense' of the axis to match the physical robot. 
At the 'Zero' Pose (J1: 0, J2:0, J3:0, J4:0 J5:-90, J6:0) the virtual and physical robot orientation match.  When I jog each axis individually, the virtual and physical robot move in the same direction.
I have a program with one target. 
The virtual target joint positions are:
J1:18.378762, J2: 1.323246, J3: -1.243727, J4: 0.024789, J5: -90.521897, and J6: 108.378218
When I load the program on the teach pendant and go to the target, the joint positions are: 
J1(S): 18.3789 , J2(L): -1.3233, J3 (U): -1.2435, J4 ®: -0.0243, J5 (B): -90.5220, J6 (T): -108.3774.

Any idea what is causing the sign to flip on joint 2,4, and 6?

Attached are the robot parameters. 

Thanks for the support, apricate it.

You can try to change the sign of the corresponding pulse/degree values:

This will invert the corresponding values of the resulting coordinates, which are output to the generated program as the number of pulses.

Hello,
Thank you for the support. Changing the sign of the pulse counts resolved the issue. Thanks again.
