Fault Type indicates if the fault is:
1 — Auto-resettable
2 — Non-resettable
3 — User-configurable
4 — Normal Fault

CODE
FAULT TYPE DESCRIPTION ACTION
ICVC FAULT
STATE
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 drive.
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). 286
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
206
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 pro-
grammed Motor NP FLA (42).
a. Reprogram Motor NP FLA (42) with the cor-
rect motor nameplate value.
b. Repeat Autotune (61).
206
79 Excessive Load Motor did not come up to speed in the allot-
ted time.
a. Uncouple load from motor.
b. Repeat Autotune (61).
206
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 capa-
bilities 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 discon-
nected, check wiring to the port. Replace
wiring, port expander, modules, Main Con-
trol board or complete drive as required.
b. Check OIM connection.
206
87 Ixo Voltage Range Ixo voltage calculated from motor name-
plate data is too high.
Re-enter motor nameplate data. 206
100 Parameter Chksum 2 The checksum read from the board does
not match the checksum calculated.
a. Press reset.
b. Reload user set if used.
206
101 UserSet1 Chksum 2 The checksum read from the user set does
not match the checksum calculated.
Press reset. 206
102 UserSet2 Chksum 2
103 UserSet3 Chksum 2
104 Pwr Brd Chksum1 The checksum read from the EPROM does
not match the checksum calculated from
the EPROM data.
Clear the fault or cycle power to the drive. 206
105 Pwr Brd Chksum2 The checksum read from the board does
not match the checksum calculated.
a. Cycle power to the drive.
b. If problem persists, replace drive.
