Troubleshooting the Drive
Rectifier Power Interface Board
1.
Verify that rectifier power interface board data is correct by checking
rectifier read-only parameter 28 (Rated Amps) against correct rectifier
output current rating.
2.
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.
3.
If drive is still faulted, attempt to reset the fault using the normal
procedure. See
Clearing Drive Faults on page 218
. If drive is still faulted
after this attempt is made, troubleshoot on the basis of the current fault.
4.
Reprogram all drive parameters.
I/O Board (AC Line I/O Board or Standard I/O Board)
No special actions are required after replacing either of these boards.
LiquiFlo 2.0 Frame 4 Firmware Setup Procedures
Combined Control Board
1.
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).
2.
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.
3.
If drive is still faulted, attempt to reset the fault using the normal
procedure. See
Clearing Drive Faults on page 218
. If drive is still faulted
after this attempt is made, troubleshoot on the basis of the current fault.
4.
Reprogram all drive parameters.
IMPORTANT
If drive fault 235 (Rctfr Pwr Board) occurs after replacing board or at any other
point during this procedure, then the new rectifier power interface board is
incompatible with the old rectifier control board, or the data stored on the old
rectifier control board has become corrupt. Replace the old rectifier control
board. If the fault still exists, replace the new rectifier power interface board.
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 control board is incompatible with the old combined power board,
or the data stored on the old combined power board has become corrupt.
Replace the old combined power board.
