The Scan Spot Position Map (300A,0394) and Scan Spot Meterset Weights (300A,0396) shall be used as follows.
For a Modulated Scan Mode Type (300A,0309) value of LEAPING or LINEAR, switching off the beam shall be prescribed and reported using a Meterset Weight of zero at the next Scan Spot Position.
The following specifies for each value of Modulated Scan Mode Type (300A,0309) the definition of the map which is included in the Control Point 1 having Cumulative Meterset Weight (300A,0134) = 20, followed by a Control Point 2 having Cumulative Meterset Weight (300A,0134) = 40.
If Modulated Scan Mode Type (300A,0309) is STATIONARY:
The beam is switched off and positioned at Scan Spot Position (6.0, 2.0).
The beam is switched off and positioned at Scan Spot Position (6.0, 3.0).
The beam is switched off and positioned at Scan Spot Position (2.0, 3.0).
The beam is switched off and positioned at Scan Spot Position (2.0, 5.0).
The beam is switched off and positioned at Scan Spot Position (7.0, 5.0).
If Modulated Scan Mode Type (300A,0309) is LEAPING:
The beam is moved and positioned at Scan Spot Position (6.0, 2.0).
The beam is delivered until a Meterset Weight of 5 is reached (including the Meterset delivered when the beam position changes).
The beam is moved and positioned at Scan Spot Position (6.0, 3.0).
The beam is delivered until a Meterset Weight of 4 is reached (including the Meterset delivered when the beam position changes).
The beam is moved and positioned at Scan Spot Position (2.0, 3.0).
The beam is delivered until a Meterset Weight of 6 is reached (including the Meterset delivered when the beam position changes).
The beam is switched off and positioned at Scan Spot Position (7.0, 5.0).
If Modulated Scan Mode Type (300A,0309) is LINEAR:
The beam is continuously delivered with a Meterset Weight of 6, while being moved from Scan Spot Position (1.0, 2.0) to Scan Spot Position (6.0, 2.0).
The beam is continuously delivered with a Meterset Weight of 4, while being moved from Scan Spot Position (6.0, 2.0) to Scan Spot Position (6.0, 3.0).
The beam is continuously delivered with a Meterset Weight of 6, while being moved from Scan Spot Position (6.0, 3.0) to Scan Spot Position (2.0, 3.0).
The beam is switched off and positioned at Scan Spot Position (7.0, 5.0).
The beam is delivered without moving from Scan Spot Position (7.0, 5.0) with Meterset Weight of 4.
