Some notes on use:
LVDTs provide position readback for x and y.
Notch Collimator:
LVDT reads positive for the blade being OUT of the beam. Furthest that the blade can be extracted is +13 mm. This will hit an OUT limit switch.
LVDT reads negative for the blade being IN the beam. -25 mm is the furthest the blade can be inserted. This will hit an IN limit switch.
COLL:LI20:2069 Notch X Mover
COLL:LI20:2072 Notch Y Mover
COLL:LI20:2073 Notch Rotation
Note: COLL:LI20:2070 is not in use. This used to be a second Y mover (physically, it is the one on the top - the y mover on the side is functional). It is not needed and is no longer connected.
Christine and Doug set soft limits for rotation based on how far it could go without collisions with cables. We set it to -145 deg and +35 deg (low and high limits). We tested this range of motion.

COLL:LI20:2086 North (High Energy) Jaw
