sine wave velocity command

Hello,

 

I'm using a NI 7342 PCI card to control a Servo Motor.

We want to generate sine waves of position in one dimension.

 

I've implemented the contour motion in MOTION ASSISTANT but the spline made between two points makes the sine wave not swooth enought (the motions stops too long during the change of direction).

I've copied the screen shoots of the sines we want to have with 2 samples and 14 samples (maximum allowed).

 

The frequency and amplitude of the motion are: 

3Hz for 5cm 

and

10Hz for 3cm.

 

Do you have any indications on how to make a smooth sinewave?

 

Thank you very much.

 

Best Regards,
