Gear Axes 217
The command position, of both the slave and master axes, is stored as the
Strobed_Position when you initiate ramped gearing.
Ramped gearing avoids the uncontrolled acceleration or deceleration
caused by enabling electronic gearing while the master axis is moving.
You can also use ramping to merge gear ratio changes on-the-fly—even
changes in direction. The motion controller automatically ramps the slave
axis to the gearing speed commanded by gearing it to the master axis at
the new ratio and/or direction.
Synchronizing Gearing on Multiple Axes
When you select Synchronize with next Gear Axes, the current Gear Axes
block executes simultaneously with the following Gear Axes block. This
lets you initiate electronic gearing on multiple axes simultaneously.
