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’.
