I've got an interesting problem that has been put on my plate.
I need to replace an old DC motor speed controller on a saw with a controller that can be integrated with an AD 205 PLC.
Here's the story - we have some ID saws on site (like the ones used to cut silicon boules) that are getting older. We recently converted one to run on an AD 205 PLC with touchscreen interface as a testbed for converting other saws. This arrangement has been working great, but one of the old parts we kept, the DC speed controller (for the blade speed) is going bad. Unfortunately, it doesn't look like we will be able to get a direct replacement for the part. It is now an opportunity to upgrade the functionality of the HMI a little more by integrating the speed controller with the PLC.
The motor being controlled is about 2HP 15A 200V DC.
I have some experience with PLCs, but this is my first foray into motor controls.
Let me know if there is more info needed. Any help would be greatly appreciated!
Thanks!
