DESCRIPTION
Input phase current imbalance exceeded
limits.
Input voltage imbalance exceeded limits.
Input power Lost.
Line frequency not in the range of
47-63 Hz.
The checksum read from the board does
not match the checksum calculated.
Inverter section of power structure hard-
ware reported unexpected fault.
Rectifier portion of power structure hard-
ware reported unexpected fault.
A fault was detected in the rectifier other
than one specifically decoded.
Precharge was closed when it should be
open.
Precharge was open when it should be
closed.
Drive rating information stored on the
power board is incompatible with the Main
Control board.
The checksum read from the board does
not match the checksum calculated.
Loss of communication to I/O board.
Board failure.
The rectifier did not regulate to the desired
bus voltage within the defined time.
Rectifier took too long to connect to
inverter.
Input power is phased ACB rather than
ABC.
ACTION
Check for loose connection in input power
wiring.
Check for problem in input power
distribution.
a. Verify proper input voltage.
b. Check line sync board and fuse.
c. Check AC line I/O board.
d. Verify connection between boards.
Verify connection between AC Line Sync and
AC Line I/O boards.
a. Restore defaults.
b. Reload user set if used.
Check wiring harness.
Check wiring harness.
Look at rectifier parameter 243 to see fault
code.
a. Check AUX contacts on precharge.
b. Check input bit 0 in rectifier parameter 216
to view status of input.
c. Check wiring.
d. Check precharge resistors and fuses.
a. Check AUX contacts on precharge.
b. Check input bit 0 in rectifier parameter 216
to view status of input.
c. Check wiring.
d. Check precharge resistors and fuses.
a. Load compatible version files into drive.
b. Cycle power to the drive.
c. If problem persists, replace drive.
a. Cycle power.
b. If fault repeats, replace I/O board.
Replace rectifier power board and/or rectifier
control board.
a. Check the cabling between the communica-
tions interface and the two control boards.
b. Connect one DPI device at a time to see if
one of the DPI devices is causing the
problem.
c. Replace the communications interface.
d. Replace the rectifier control board.
Switch two of the input power phases.
