o 3. Main Control/CPU Board Replacement
a) Assure that all power has been removed and 30 seconds has elapsed.
b) Remove the front cover from the drive. Refer to the ESD precaution
on page 1 and apply grounding wrist strap.
Important: The supplied grounding wrist strap must be worn during
this procedure to protect the IGBT gate leads against ESD damage.
c) Label and remove any cables from the I/O Board. Remove the I/O
Board (with Display & Keypad Module) by taking the four screws
out and carefully separating the connectors.
d) Label and remove any cables from the CPU/Main Control Board.
Remove the board by taking out the six screws that secure it.
e) An EPROM is located on the Main Control/CPU Board which must
be moved to the new board. Using Figure 1, find the location for this
EPROM.
f) Carefully remove the existing EPROM from its socket (note notch
orientation).
Important: It is recommended that a chip (integrated circuit) puller
be used. If a puller is not available, a less desirable alternative is to
use a small, flat blade screwdriver. The screwdriver is first inserted
under one end of the EPROM and then the other end. This method
can be used to help lift the IC from its socket. If the screwdriver
method is used, extreme caution must be taken so that surrounding
components and board traces are not damaged.
g) Carefully insert the EPROM into position on the new board (note
orientation). Care must be used to assure that all pins are properly
aligned and inserted. After insertion, assure that all pins are properly
seated in the socket.
h) Install the new Main Control/CPU Board. Re-connect any cables that
were previously removed. On 8510A-A11/A22 drives, assure that the
Main Control Board is properly seated with the Power Board via the
three Interconnect Boards.
Important: Do Not touch the gold edge connectors on the
Interconnect Board – contamination could result, causing poor
connections. In addition, ESD could damage the IGBT gate leads.
i) Replace the I/O Board (with Display & Keypad Module). Assure that
the board connectors are fully seated. Re-connect any cables that were
previously removed.
j) Replace drive cover and remove wrist strap. Check for proper
operation.
