Have checked polarity of the LVDTs and actuator coils of the TMS-VISX. See here for details.
I moved the suspended table by my finger while looking at VIS-TMSX_LVDTINF_**_INMON:
- Vertical: postive means that the LVDT outputs positive counts when TMS-VIS moves upward.
- Horizontal: postive means that the LVDT outputs positive counts when TMS-VIS moves positive yaw (counter clock wise from top view).
We input positive counts to the actuator coils while looking at raw LVDT signals (VIS-TMSX_LVDTINF_**_INMON):
So, considering the polarity of the LVDTs themselves shown in the first table, all the actuator coil provide force toward positive firection (vertical->upward, yaw->counter clock wise).
