EMCS PLC controls Enclosure Azimuth motion in these routines

• EMCS / Azimuth / Control Speed
  Setup Control Loop:
  Position and Speed Reference
  Position Error control modes
  Tuning parameters
  Speed limits
  Response times

• EMCS / Azimuth / Control Loop
  Calculate Speed Reference to Azimuth Drives for Position Control or Speed Control

EMCS PLC controls Enclosure Azimuth motion in two modes

• Position Control
  Operate to maintain Actual Position = Position Reference

• Speed Control
  Operate to move Azimuth at Speed Reference

Position Control

PI (Proportional / Integral) closed loop control
