Enclosure Azimuth motion is controlled by the EMCS PLC. Motion is commanded from the ECS or locally.
ECS can control motion in four modes
Tracking - ECS sends Position Reference and Speed Reference
Point to Point - ECS sends Position Reference and sometimes sends Speed Reference
Jogging and Offset - modes are not used
Local motion includes Point to Point and Jogging
EMCS PLC controls Enclosure Azimuth motion in these routines
EMCS Azimuth / Control Speed
EMCS Azimuth / Control Loop
