Product Advisories: SD3000 PLUS DC Drive Regulator Gate Driver Output board
Ref: CPAG 2005-06-001
Date: June, 2005
Problem Description
There may be a clearance problem between the rear three mounting screws on the SD3000 PLUS Gate Driver Output (GDO) board and the traces for the regulator internal common connection. The mounting screws are connected to chassis ground. If the GDO printed circuit board is not centered on the mounting screws, the captive washers on the three rear mounting screws will align on top of the printed circuit board traces for the internal regulator common and may wear through the solder mask.
If the solder mask wears through, then there could be a short connection between the chassis ground and the internal regulator common, combine that with electrical noise, it may result in intermittent shut down of the drive.
Problem Correction
To resolve this issue, we recommend installing plastic insulating washers to the three rear mounting screws on the GDO board. Rockwell will supply all affected units with a washer template (contains 4 plastic washers) part number 195341 Rev. 02 and the instruction sheet Publication DSSD3P-SB001A-EN-E – May, 2005.
Details of all affected shipments are identified. All affected customers will be notified with details on the affected installation and supplied by RA personnel with a washer template and instructions. We will work with each of our customers individually to avoid any unnecessary inconveniences. There are four plastic washers per sheet of 195341 Rev. 02 material. Three of the four washers will be used. The instruction sheet will be issued with the washer template to all affected customers.
