We have an very old welding machine for stainless steel metal sheets where the welding torch is fixed on bracket and is moved by a gearbox motor which is controlled by an ac drive.
The operator sets the system in motion and it's start welding until a mechanical limit switch stops the ac drive.
The speed and the position of the limit switch are set manually by the operator depending on metal sheet thickness and and length.
We wan't make the process a little bit more automatic.
The obvious solution is to use a servo system but I think it would be overkill for the particular application since the required position precision is around 2mm.
I guess it's possible to install an encoder on the motor and then use an ac drive (vfd) in closed loop for position control.
I'm not very experienced in motion control applications so I need some help with this.
