Drive Processor Module Replacement
Before replacing the Drive Processor Module, it is important to record all of the
programmed drive parameters and settings. Specifically, the parameters, fault
masks, fault descriptions, and PLC links are critical. This information is stored in
NVRAM on each, and as a result you may lose your settings with a new board.
The best method to record parameters is to use the memory on the terminal.
Other options include a flashcard, HyperTerminal, the door-mounted printer, or
DriveToolsâ„¢ software to record the parameters to a file. The printer and
HyperTerminal options allow you to print all of the drive setup information.
Otherwise, recording information by hand is the only option left. In the situation
where a board has failed, you probably will not be able to save parameters after
the failure. That is why it is important to save all parameters when you are
finished commissioning or servicing the drive. In this case you should contact the
customer to see if they have a copy of the last parameters, or contact Product
Support to check if they have a copy.
Instructions to Replace the Drive Processor Module
1. Record all drive setup information using any of the options above, if
possible.
2. Ensure that all medium voltage and control voltage power to the drive is
isolated and locked out.
3. It is required to first remove the transparent sheet on top of the Drive
Processor Module by removing the 4 screws.
4. Use static strap before removing any connectors.
5. Remove the connectors J4, J11 and J12 after proper identification and
marking if necessary. Use the electrical drawing as the reference.
6. Remove the 4 screws on the corners of the board fastening the board to the
standoffs on the Analog Control Board ACB.
7. Gently remove the Drive Processor Module from the four, 34 pin female
connectors and one, 16 pin female connector on the ACB.
8. Remove the DIM module from the DPM and plug it on the new DPM
before the replacement of DPM.
9. Follow Steps 7 – 3 in reverse to re-install the boards back into the low
voltage control cabinet.
