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 DriveTools
TM
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.
10. Apply control power to the drive. The DPMs are shipped with
no firmware installed, so the drive will automatically go into
download mode. Install firmware in the drive following the
guidelines in ‗Installing Firmware‘.
