6–5 Troubleshooting
Name & Fault # Action Description
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% (50% on A Frame
drives) 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 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 A2, A3 – Check the
precharge circuit. Replace the
precharge NTC or complete
drive as needed.
2. Frame B – Check the prechar-
ge circuit. Replace the prechar-
ge transistor, Power Driver
Board or complete drive as
required.
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 A2, A3 – Check the
precharge circuit. Replace the
precharge NTC or complete
drive as needed.
2. Frame B – Check the prechar-
ge circuit. Replace the prechar-
ge transistor, Power Driver
Board or complete drive as
required.
Reprogram Fault
48 The drive was commanded to
write default values to
EEPROM. 1. Clear the fault or cycle power
to the drive.
2. Program the drive parameters
as needed.
Important: If [Input Mode] has
been changed from its original
value, power must be cycled
before the new value will take
affect.
ROM or RAM Flt
68 Internal power-up ROM or
RAM tests have not executed
properly. Check Language Module.
Replace Control Board or
complete drive as required.
Run Boost Fault
34 An attempt has been made to
set the [Run Boost] parameter
to a value greater than the
[Start Boost] parameter. Verify that parameter has been
programmed correctly.
