FAULT
STATE
2 Auxiliary Input 1 Input is open. Check remote wiring. 206
3 Power Loss 1, 3 DC bus voltage remained below 85% of nominal for longer than
Power Loss Time (185). Enable/disable with Fault Config 1 (238).
Monitor the incoming AC line for low voltage or line
power interruption.
215
4 UnderVoltage 1, 3 DC bus voltage fell below the minimum value of 407V DC at
400/480V input. Enable/disable with Fault Config 1 (233).
Monitor the incoming AC line for low voltage or power
interruption.
215
5 OverVoltage 1 DC bus voltage exceeded maximum value. Monitor the AC line for high line voltage or transient
conditions. Bus overvoltage can also be caused by
motor regeneration. Extend the decel time or install
dynamic brake option.
205
7 Motor Overload 1, 3 Internal electronic overload trip. Enable/disable with Fault Config 1
(238).
An excessive motor load exists. Reduce load so drive
output current does not exceed the current set by Motor
NP FLA (42).
217
8 Invtr Base Temp 1 Base temperature exceeded limit. Check for proper temperature and flow rate of coolant. 219
9 Invtr IGBT Temp 1 Output transistors have exceeded their maximum operating
temperature.
Check for proper temperature and flow rate of coolant. 219
12 HW OverCurrent 1 The drive output current has exceeded the hardware current limit. Check programming. Check for excess load, improper
DC boost setting, DC brake volts set too high or other
causes of excess current.
286
13 Ground Fault 1 A current path to earth ground in excess of 7% of drive rated amps
has been detected at one or more of the drive output terminals.
Check the motor and external wiring to the drive output
terminals for a grounded condition.
220
24 Decel Inhibit 3 The drive is not following a commanded deceleration because it is
attempting to limit bus voltage.
a. Verify input voltage is within drive specified limits.
b. Verify system ground impedance follows proper
grounding techniques.
c. Disable bus regulation and/or add dynamic brake
resistor and/or extend deceleration time.
204
25 OverSpeed Limit 1 Functions such as slip compensation or bus regulation have
attempted to add an output frequency adjustment greater than that
programmed in Overspeed Limit (83).
Remove excessive load or overhauling conditions or
increase Overspeed Limit (83).
206
29 Analogue In Loss 1, 3 An analogue input is configured to fault on signal loss. A signal loss
has occurred. Configure with Anlg In 1, 2 Loss (324, 327).
a. Check parameters.
b. Check for broken/loose connections at inputs.
206
33 Auto Rstrt Tries 3 Drive unsuccessfully attempted to reset a fault and resume running
for the programmed number of Auto Rstrt Tries (174).
Enable/disable with Fault Config 1 (238).
Correct the cause of the fault and manually clear. 206
35 Current Fbk Lost 4 The magnitude of motor current feedback was less than 5% of the
configured Motor Nameplate Amps for the time configured in the
Motor Imbalance Time. Detection of this fault is disabled when the
Motor Imbalance Time is set to the maximum value of 10.0 seconds.
Verify connection of current feedback device and motor
terminals. If fault repeats, replace current feedback
devices and/or power supply.
206
36 SW OverCurrent 1 The drive output current has exceeded the software current. Check for excess load, improper DC boost setting. DC
brake volts set too high.
286
37 Motor I Imbalance 4 Phase current displayed in Imbalance Display (221) > percentage
set in Imbalance Limit (49) for time set in Imbalance Time (50).
Clear fault. 225
38 Phase U to Grnd A phase-to-ground fault has been detected between the drive and
motor in this phase.
a. Check the wiring between the drive and motor.
b. Check motor for grounded phase.
c. Replace drive.
220
39 Phase V to Grnd
40 Phase W to Grnd
41 Phase UV Short Excessive current has been detected between these two output
terminals.
a. Check the motor and drive output terminal wiring
for a shorted condition.
b. Replace drive.
246
42 Phase VW Short
43 Phase UW Short
48 Params Defaulted The drive was commanded to write default values to EPROM. a. Clear the fault or cycle power to the VFD.
b. Program the drive parameters as needed.
206
63 Shear Pin 3 Programmed Current Lmt Val (148) has been exceeded. Enabled/
disable with Fault Config 1 (238).
Check load requirements and Current Lmt Val (148)
setting.
206
64 Drive OverLoad Drive rating of 110% for 1 minute or 150% for 3 seconds has been
exceeded.
Reduce load or extend Accel Time (140). 246
70 HW Fault 4 Inverter section of power structure hardware detected an
unexpected fault during power stage diagnostics.
a. Cycle power.
b. Call Carrier Service.
206
71- 75 Port 1-5 Net Loss The network card connected to DPI port stopped communicating.
The fault code indicates the offending port number (71 = port 1, 72
= port 2, etc.)
a. Check communication board for proper connection
to external network.
b. Check external wiring to module on port.
206
76 Peripheral Fault at DPI
Port 6
77 IR Volts Range The drive autotuning default is Calculate, and the value calculated
for IR Drop Volts is not in the range of acceptable values.
Re-enter motor nameplate data. 206
78 FluxAmpsRef Rang The value for flux amps determined by the autotune procedure
exceeds the programmed Motor NP FLA (42).
a. Reprogram Motor NP FLA (42) with the correct
motor nameplate value.
b. Repeat Autotune (61).
206
79 Excessive Load Motor did not come up to speed in the allotted time. a. Uncouple load from motor.
b. Repeat Autotune (61).
203
80 AutoTune Aborted The autotune procedure was canceled by the user. Restart procedure. 206
81- 85 Port 1-5 DPI Loss DPI port stopped communicating. An attached peripheral with
control capabilities via Logic Source Sel (89) (or OIM control) was
removed. The fault code indicates the offending port number (81 =
port 1, etc.)
a. If module was not intentionally disconnected, check
ribbon cables, connectors, and pins. check wiring
to the port. Replace wiring, port expander, modules,
Main Control board or complete drive as required.
b. Check OIM connection.
206
Fault Type indicates if the fault is:
