API field
Rotation minimum
The lower rotation stop; empty = minus the symmetric stroke
Unit °
What it is
The lower mechanical stop of the tracker rotation, in degrees. Rotation is counted positive when the plane faces the azimuth plus 90°, so for an axis azimuth of 180° a negative value is the east-facing stop. Empty uses minus the symmetric stroke.
Typical values and how to get it
Leave it empty unless the stroke is asymmetric; then the datasheet's lower limit.
