Yes you are right,
The prodcut line has a constant velocity all the time, and i only can control carriage velocity, assume that the desired length to cut is Y,And V is product velocity and carriage is in home position, After T,product will be in new position with length of Y+X, so if carriage at X position reach to velocity of V and reamin constant after that, there is 2 equations, 1- X=V*T (the product travelling distance) 2- X=1/2*aT^2(the travelling distance by carriage acceleration) so a=2V/T now how can i reach to carriage acceleration of (a) at X position? a servo drive with +/-10V speed reference is exist there, |
