Driver problems on DIP insertion machine | 22 September, 1999

The machine is a Universal 6796 DIP inserter. The driver card for the X axis burned a couple of resistors and a trace, probably a couple of power transistors too. I had a spare card and put it in. Now on powering-up the machine, the X-Y table moves slowly to the left and stops only when it hits the mechanical stop. The limit switches are testing good.

I welcome any insights.

This guy is great with Dynapert equipment and has very reasonable service rates. (315)589-4094 is the number to his shop. | |
