Inverter Power Interface Board
1. Verify that inverter power interface board data is correct by checking
inverter read-only parameter 28 (Rated Amps) against correct drive
output current rating.
2. 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).
3. The reset to defaults operation normally causes drive fault 48 (Params
Defaulted) to occur. This fault is for information only, and should be
cleared. 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.
4. Reprogram all drive parameters.
Rectifier Control Board
1. 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.
2. 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.
3. Reprogram all drive parameters.
IMPORTANT If drive fault 106 (Incompat MCB-PB) occurs after replacing board or at any
other point during this procedure, then the new inverter power interface board
is incompatible with the older inverter control board. Replace the older
inverter control board.
IMPORTANT If drive fault 235 (Rctfr Pwr Board) occurs after replacing board or at any other
point during this procedure, then the new rectifier control board is
incompatible with the older rectifier power interface board, or the data stored
on the old rectifier power interface board has become corrupt. Replace the
older rectifier power interface board.
