MoveTrapezoidal() [2/3]

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

pure virtual

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

Description:

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.

Parameters

position	Target Position in units.
vel	Maximum velocity, units/second.
accel	Maximum accleration , units/second/second.
decel	Maximum deceleration , units/second/second.

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.

Sample Code:

axis->MoveTrapezoidal(5000.0, 10000.0, 100000.0, 100000.0);

RapidSetup:

Go to Axis->Motion (default tab)

Motion Scope:
