◆ MoveTrapezoidal() [2/3]

void MoveTrapezoidal ( double  position,
double  vel,
double  accel,
double  decel 

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

MoveTrapezoidal commands a point-to-point motion with a trapezoidal velocity profile. This has a trapezoidal shape for the velocity with constant acceleration and deceleration phases.
positionTarget Position in units.
velMaximum velocity, units/second.
accelMaximum accleration , units/second/second.
decelMaximum deceleration , units/second/second.
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.
This function is also available in RapidSequencer.

Part of the Motion method group.

Sample Code:
axis.MoveTrapezoidal(Constants.POSITION, Constants.VELOCITY, Constants.ACCELERATION, Constants.DECELERATION);// Command simple trapezoidal motion.
axis.MotionDoneWait();// Wait for motion to be done
Go to Axis->Motion (default tab)
Motion Scope:
