This FourCorp seam welder was originally built using a Baldor MINT smart drive and CAN-Bus HMI panel. The MINT drive had failed and it's program had become corrupted, but that was only the beginning. The MINT drive was obsolete and the new MINT-II that replaced it incompatible; the software is different, the connectors are different, and the 24 volt power supply, integral to the MINT drive, has been eliminated from the MINT-II.
The software was analyzed and re-written for the MINT-II drive, with IO reassigned to minimize connector and wiring changes. A new 24-volt power supply was added added to the cabinet, the required wiring changes were made, and wires were re-labeled to reflect both the old numbers (corresponding to the printed documentation) and the new numbers (corresponding to the connector assignments on the MINT-II drive). A few hours of debugging (and the implementation of a few new features requested by the operator!) and this machine was brought back to life.
