IEC Command Codes
Home Commands
HB Home Beam Limiter
Homes all four shutters; right, left, top and bottom. At the completion of this
command the shutters are all open and at a position of zero.
Upon completion of the HB command it is recommended to move all four shutters
to a position of 10 steps. This avoids a potential lockup issue on version 4 of the
Beam Limiter assembly once powered off.
HP Home Platform
Homes the platform axis to the rear of the gantry and sets the position to 1500.
HFR Home Rotation Fast
Homes the rotation drive from any location such that the Tube-Head and Beam
Limiter assembly are located perpendicular to patients’ right when seated. This
position is then set to be 100000 in stepper motor space. Subsequent
MR 100000 commands will move back to this position.
HSR Home Rotation Short
Performs a quick check within approximately 1 degree of the current location for
home. If home is not located, the rotation proceeds to perform an HFR. If the
rotation is already home, this command will complete much more quickly.
