3.1.4 Speed/position switching control
• It change speed control to position control by switching command (VTP instruction).
• In case of speed/position switching control, items affecting the operation are different according to
control method.
- First, object moves by speed control. If speed/position switching control is executed, target will
move by position control.
- At this time, position control is executed by absolute coordinates with initializing the current
position as 0. So coordinates item doesn’t affect the operation.
- Since control method also changes by speed/position switching, control method in the operation
data doesn’t affect the operation.
- In case of speed/position switching, object keeps its previous direction.
