RolloverCounts Parameter

Use the RolloverCounts parameter to enable position rollover (modulo) and to specify the number of encoder counts at which the position rolls over. To enable rollover, set the RolloverCounts parameter to a non-zero value. To disable rollover, set the RolloverCounts parameter to zero.

When the RolloverCounts parameter is enabled, each time the axis moves the number of counts defined by this parameter, the display of Program Position Feedback and Program Position Command rolls over at zero. See the example that follows.

This parameter has an effect on the Axis Dashboard display of the Develop Workspace. When you are in absolute programming mode, it also has an effect on the target position of absolute motion functions such as MoveAbsolute() or MoveLinear(). You can use the RolloverMode Parameter to specify that the axis moves in the direction that has the shortest distance of travel in this mode. When you are in incremental programming mode, the RolloverCounts parameter does not have an effect on the target position of incremental motion functions such as MoveIncremental() or MoveLinear().

In the Data Visualizer module, the position feedback and position command do not roll over. An artificial step does not show in the plotted position. This does not change actual motion and applies only to the display in the Data Visualizer. To use the condensed version of this module in the Develop workspace, see Data Visualizer Module. To use the larger version of this module in the Visualize workspace, see Visualize Workspace.
