Combined Power Board
1. Verify that power board inverter data is correct by checking inverter read-
only parameter 28 (Rated Amps) against correct drive output current
rating.
2. Verify that power board rectifier data is correct by checking rectifier read-
only parameter 28 (Rated Amps) against correct rectifier output current
rating
3. Reset all inverter parameters to defaults by setting inverter parameter 197
(Reset to Defalts) to 1. The value of parameter 197 (Reset to Defalts)
returns to 0 immediately after 1 is written to memory. This action should
clear faults 100 (Parameter Checksum) and 107 (Replaced MCB-PB).
4. Reset all rectifier parameters to defaults by setting rectifier parameter 197
(Reset to Defalts) to 1. The value of parameter 197 (Reset to Defalts)
returns to 0 immediately after 1 is written to memory.
5. If drive is still faulted, attempt to reset the fault using the normal
procedure. See Clearing Drive Faults
on page 222. If drive is still faulted
after this attempt is made, troubleshoot on the basis of the current fault.
6. Reprogram all drive parameters.
Standard I/O Board Connections
Mount the Standard I/O Board on the Power Module with hardware provided.
IMPORTANT
If drive fault 106 (Incompat MCB-PB) or fault 235 (Rctfr Pwr Board) occurs after
replacing board or at any other point during this procedure, then the new
combined power board is incompatible with the old combined control board,
or the data stored on the old combined control board has become corrupt.
Replace the old combined control board. If the fault still exists, replace the new
combined power board.
