MoveSCurve() [2/3]

void MoveSCurve	(	double	position,
		double	vel,
		double	accel,
		double	decel,
		double	jerkPct
	)

Description:

MoveSCurve command a point-to-point motion, with an S-Curve velocity profile.
This type of motion has an "S" shape to the acceleration and deceleration phases. It uses the JerkPercent parameter to decide how much of the acceleration and deceleration phases is curved. A JerkPercent of zero produces a trapezoidal profile.

Parameters

position	Target Position in units.
vel	Maximum velocity, units/second.
accel	Maximum accleration , units/second/second.
decel	Maximum deceleration , units/second/second.
jerkPct	Jerk Percent, which defines the percentage of acceleration time which is smoothed, 0.0 to 100.0 .

Note

In most cases, a servo motor has a feedback device mounted. Depending on feedback device resolution, one motor shaft rotation will produce fixed value of counts. Example: motor has a resolution of 8192 counts. This means if 8192 is entered as distance to move, motor will move single revolution. User can implement UserUnitsSet() to change to a different unit (ex: mm, inches, etc) from encoder counts.

Remarks

This function is also available in RapidSequencer.

Part of the Motion method group.

Sample Code:

SCurveMotion

      axis.MoveSCurve(Constants.POSITION); // Command SCurve Motion. This overload willuse default velocity, acceleration, deceleration, jerk values for the axis. See axis config to learn how to set those values.
      axis.MotionDoneWait();               // Wait for motion to finish

RapidSetup:

Go to axis screen->Motion Profile box (left) to select type of motion
Go to axis screen->Motion Parameters box (right) to select values for motion
