6–5 Troubleshooting
Name & Fault # Action Description
Phase V Fault
39 A phase to ground fault has
been detected between the
drive and motor in this phase. Check the wiring between the drive
and motor. Check motor for
grounded phase.
Phase W Fault
40 A phase to ground fault has
been detected between the
drive and motor in this phase. Check the wiring between the drive
and motor. Check motor for
grounded phase.
P Jump Err Flt
37 Reserved for future use.
Poles Calc Flt
50 Generated if the calculated
value of [Motor Poles] is less
than 2 or greater than 32. Check [Motor NP RPM] and [Motor
NP Hertz] programming.
Power Loss Fault
03 DC bus voltage remained
below 85% of nominal for
longer than 500ms. [Line Loss
Fault] parameter is set to
“enabled.” Monitor the incoming AC line for
low voltage or line power
interruption.
Power Mode Fault
26 The internal power mode
variable received an incorrect
value. Check all connections to the
Control Board. Replace the board,
Language Module or complete
drive as required.
Power Overload
64 The drive rating of 150% for 1
minute has been exceeded. Reduce load.
Power Test Flt
46 The internal power mode
variable received an incorrect
value. Check all connections to the
Power/Driver Board. Replace the
board or complete drive as needed.
Precharge Fault
19 The precharge device was
open 20ms after the end of a
line loss condition or the bus
charging alarm remains on for
20 seconds (precharge did not
complete). See Chapter 1 for frame
definitions.
1.Frames A1, A2, A3 – Check the
precharge circuit. Replace the
precharge NTC or complete
drive as needed.
2. Frame B – Check the precharge
circuit. Replace the precharge
transistor, Power Driver Board or
complete drive as required.
3. All larger frames – Check the
precharge circuit. Replace the
input SCRs, SCR Firing Board,
Power Driver Board or complete
drive as needed.
Precharge Open
56 The precharge circuit was
commanded to close, but was
detected to be open. See page 1–1 for frame definitions.
1.Frames A1, A2, A3 – Check the
precharge circuit. Replace the
precharge NTC or complete
drive as needed.
2. Frame B – Check the precharge
circuit. Replace the precharge
transistor, Power Driver Board or
complete drive as required.
3. All larger frames – Check the
precharge circuit. Replace the
input SCRs, SCR Firing Board,
Power Driver Board or complete
drive as needed.
