Optimization case 4 – y-axis is the master axis, y-axis is in lowering mode
Initial situation: tyVmax > txVmax
The y-axis is the master axis because its travel time is longer than that of the x-axis due to a longer travel distance and the dynamic parameters.
The y-axis is in lowering mode.
Optimization parameters: tyVmax = txVadjusted
The y-axis starts immediately and is operated with the maximum dynamic parameters to achieve the required cycle time. The x-axis also starts immediately but travels at a reduced speed.
The speed of the x-axis is calculated so that the x-axis completes its travel motion when the y-axis begins to decelerate.
Energy saving:
As the speed of the x-axis is reduced, this axis uses less energy. The energy generated by lowering the y-axis is made available to the x-axis.
