Description

MPIMotionAttrHold combines existing MPIMotionAttrHold and MPIMotionAttrHoldSource, and moves logic type from attributes to the structure itself.

Sample Code

The following code takes a set of position, velocity, and acceleration values and starts a multi-axis coordinated move. 

  void startMove(MPIMotion motion,
                 double position,
                 double velocity,
                 double acceleration) {
                 
       MPI_RESULT returnValue;
       int32_t index;
       int32_t axisCount;
       double *pos;
       
       mpiMotionAxisCount(motion, &axisCount);
       
       pos = malloc(sizeof(double) * axisCount);
       
       for(index = 0; index < axisCount; index++) {
           pos[index] = position;
       }
       
       returnValue =
          mpiMotionSimpleTrapezoidalCartesian(motion, pos, velocity, acceleration);
          msgCHECK(returnValue);
          
       free(pos);
     }
