STATE
225 Input Amp
Imbalance
Input phase current imbalance exceeded
limits.
Check for loose connection in input power
wiring.
209
226 Input Volt
Imbalance
Input voltage imbalance exceeded limits. Check for problem in input power
distribution.
216
227 AC Line Lost Input power Lost. a. Verify proper input voltage.
b. Check line sync board and fuse.
c. Check AC line I/O board.
d. Verify connection between boards.
210
228 Line Frequency Line frequency not in the range of
47-63 Hz.
Verify connection between AC Line Sync and
AC Line I/O boards.
222
229 Rectifier
Checksum
The checksum read from the board does
not match the checksum calculated.
a. Restore defaults.
b. Reload user set if used.
206
230 Inverter HW
Unknown 4
Inverter section of power structure hard-
ware reported unexpected fault.
Check wiring harness. 206
231 Rectifier HW
Unknown 4
Rectifier portion of power structure hard-
ware reported unexpected fault.
Check wiring harness. 206
232 Rctfr Not OK A fault was detected in the rectifier other
than one specifically decoded.
Look at rectifier parameter 243 to see fault
code.
200
233 Precharge closed Precharge was closed when it should be
open.
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.
206
234 Precharge open Precharge was open when it should be
closed.
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.
206
235 Rctfr Pwr Board 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.
Load compatible version files into drive.
a. Cycle power to the drive.
b. If problem persists, replace drive.
206
236 Rctfr I/O Board Loss of communication to I/O board.
Board failure.
Cycle power.
a. Cycle power.
b. If fault repeats, replace I/O board.
206
237
Not At Voltage 4 The rectifier did not regulate to the desired
bus voltage within the defined time.
Replace rectifier power board and/or rectifier
control board.
206
238 Rectified Not Log
In 4
Rectifier took too long to connect to
inverter.
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.
206
239 Power Phased ACB 4 Input power is phased ACB rather than
ABC.
Switch two of the input power phases. 206
