The network card connected to DPI port stopped
communicating on its external network.
The fault code indicates the offending port number
(71 = port 1, etc.)
1. Check communication board for proper connection to external network.
2. Check external wiring to module on port.
3. Verify external network fault.
Port 1...6 DPI Loss 81

DPI port stopped communicating via DPI, or an attached
peripheral with control capabilities was removed. Fault 82
indicates specifically that the rectifier stopped
communicating with the inverter.
1. If DPI device was not intentionally disconnected, check wiring to the
port. Replace wiring, port expander, peripherals, control board as
required.
2. If fault 82 occurs, disconnect all external peripherals and cycle power to
drive. If fault 82 recurs, replace control board.
Power Loss 3
Input power unavailable or AC line synchronization not
possible for longer than inverter Power Loss Time (185).
Enable/disable with inverter Fault Config 1 (238).
1. Monitor the incoming AC line for low voltage or line power interruption.
2. Check AC line voltage feedback wiring and signal path. This includes the
Combined I/O board and the Combined Control board.
Power Phased ACB 239 Input power is phased ACB rather than ABC. Switch two of the input power phases.
Precharge Closed 233 One or more precharge contactors was closed when it should
be open.
1. Check AUX contacts on precharge contactor(s).
2. Check bit 15 in rectifier parameter Dig In Status (216) to view status of
input.
3. Check wiring.
Precharge Opened 234 One or more precharge contactors was open when it should
be closed.
1. Check AUX contacts on precharge contactor(s).
2. Check bit 15 in rectifier parameter Dig In Status (216) to view status of
input.
3. Check wiring.
Pwr Brd Chksum1 104 The checksum read from the Combined Power board inverter
EEPROM does not match the checksum calculated from the
EEPROM status data.
Clear the fault or cycle power to the drive.
Pwr Brd Chksum2 105 The checksum read from the Combined Power board inverter
EEPROM does not match the checksum calculated from the
EEPROM configuration data.
1. Check connections between Combined Control board and Combined
Power board. If this fixes the problem, use inverter Reset To Defaults
(inverter 197) and rectifier Reset To Defaults (rectifier 197) to reset all
drive parameters to defaults, then reconfigure drive as necessary.
2. If problem persists, replace power board.
Rctfr Base Temp 217 Measured temperature of one of the rectifier IGBT modules
exceeded limits.
Check for proper temperature and flow rate of coolant.
Rctfr Checksum 229 The parameter checksum read from the rectifier portion of the
control board does not match the checksum calculated, or the
control board or power board has been replaced.
1. Clear fault.
2. If fault persists, restore defaults on rectifier (rectifier parameter 197),
then reprogram rectifier parameters.
3. If fault still persists, replace control board or power board.
Rctfr DPI Comm 246 DPI communications interrupte

rectifier.
1. Clear fault.
2. If fault recurs or persists, replace control board.

Rctfr Gnd Fault 216 Excessive line side (input) ground current measured. Check for grounded input wiring.
Rctfr HW Unk 231 Rectifier portion of power structure hardware reported
unexpected fault.
1. Verify connections between control board and power board.
2. If fault persists, replace power board.
3. If fault still persists, replace control board.
