Imposed velocity after a specific time

Hi,

 

I would like to impose to a motor axis a velocity from a specific time until the end of my simulation. Before this specific time I want to leave this motor axis free.

From 0s to 2s the motor axis must be free.

From 2s to 5s I want to  the impose an angular velocity to the motor axis which follow a curve.

 

Do you have an idea?

 

Thanks

 

Damien

    Two ways,

     

    One is using a curve- Create a curve and source the same on the motion. SImple way.

     

    The other way is using expressions.- You can use IF function to create the desired motion

     

    If(TIME-2:0,0,Expression)
