Subject: Pro-Dex OMS MAXv card reading limit-switches

Using OMS MAXv-card i always get only the the state of the PLUS-LS

Never the MINUS_LS even if i change the wiring (PLUS-LS <-> MINUS-LS)

The switche input is low when hit

Motor-6.5

MSTA R Motor Status ULONG The motor status as received from the hardware. The MSTA bits are defined as follows:

       1. DIRECTION: last raw direction; (0:Negative, 1:Positive)
       2. DONE: motion is complete.
       3. PLUS_LS: plus limit switch has been hit.
       4. HOMELS: state of the home limit switch.
       5. Unused
       6. POSITION: closed-loop position control is enabled.
       7. SLIP_STALL: Slip/Stall detected (eg. fatal following error)
       8. HOME: if at home position.
       9. PRESENT: encoder is present.
      10. PROBLEM: driver stopped polling, or hardware problem
      11. MOVING: non-zero velocity present.
      12. GAIN_SUPPORT: motor supports closed-loop position control.
      13. COMM_ERR: Controller communication error.
      14. MINUS_LS: minus limit switch has been hit.
      15. HOMED: the motor has been homed.

The record is put into MAJOR STATE alarm if either SLIP_STALL or PROBLEM bits are detected. If HLSV is set, then the record is put into HIGH alarm if either a high soft limit or hard limit (PLUS_LS) has been reached. Similary for the low limits.
