Replacing the Drive Processor Module
Before replacing the drive processor module, record all of the programmed
drive parameters and settings; specifically, the parameters, fault masks, fault
descriptions, and PLC links. This information resides in NVRAM on each
board, and as a result you may lose your settings with a new board. Save
parameters in the terminal memory. Other options include a flashcard,
HyperTerminal, the door-mounted printer, or DriveTools™ software to record
the parameters to a file. The printer and HyperTerminal options enable you to
print configuration information. Otherwise, record information by hand. If a
board fails, you likely cannot save parameters after the failure.
Save all parameters after commissioning or servicing the drive. If you do not
have a copy of the initial configuration or current parameters, contact your
Rockwell sales or service representative or Product Support to check if they
have a copy.
1. Record all drive configuration using one of the options above.
2. Isolate and lock out all medium voltage and control voltage power to the
drive.
3. Remove the transparent sheet on top of the drive processor module by
removing the four screws.
4. Use a grounding 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 four screws on the corners of the board fastening the board
to the standoffs on the analog control board.
7. 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 replacing the DPM.
9. Reverse steps 7…3 to re-install the boards into the low voltage control
cabinet.
10. Apply control power to the drive. The DPMs ship without installed
firmware, so the drive will shift into download mode. Install firmware in
the drive by following the guidelines the installation manual.
11. Program the drive. See publication 7000-TD002
. Save the parameters to
NVRAM and externally, using the options described earlier in this
section.
