CODE
FAULT TYPE* DESCRIPTION ACTION
FAULT
STATE
48 Params Defaulted 4 The drive was commanded to write
default values to EEPROM.
1. Press ICVC RESET key or cycle power to the
VFD.
2. 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 MOTOR RATED LOAD AMPS setting in
VFD_CONF screen.
206
64 Drive OverLoad 4 Drive rating of 102% for 1 minute or
150% for 5 seconds has been
exceeded.
Check RATED LINE AMPS and MOTOR RATED
LOAD AMPS in VFD_CONF screen.
246
70 HW Fault 4 Inverter section of power module
detected an unexpected fault during
power stage diagnostics.
Contact Carrier Service 206
71- 75 Port 1-5 Net Loss 4 The network card connected to DPI port
stopped communicating.
The fault code indicates the offending
port number (71 = port 1, 72 = port 2,
etc.)
1. Check communication board for proper
connection to external network.
2. Check external wiring to module on port.
Check ribbon cables, connectors, and pins.
3. Verify external network fault.
206
77 IR Volts Range 4 The drive autotuning default is calcu-
lated, and the value calculated for IR
Drop Volts is not in the range of accept-
able values.
Check Motor Nameplate parameters in
VFD_CONF screen.
206
78 FluxAmpsRef Rang 4 The value for flux amps determined by
the autotune procedure exceeds the
programmed Motor NP FLA (42).
Check MOTOR NAMEPLATE AMPS in
VFD_CONF screen.
206
79 Excessive Load 4 Motor did not come up to speed in the
allotted time.
1. Check parameters in VFD_CONF screen.
2. Contact Carrier Service.
203
80 AutoTune Aborted 4 The autotune procedure was canceled
by the user.
Press ICVC RESET key to restart procedure. 206
81- 85 Port 1-5 DPI Loss 4 DPI port stopped communicating.
An attached peripheral with control
capabilities via Local Mask (288) (or
O I M c o n t r o l ) w a s r e m o v e d .
The fault code indicates the offending
port number (81 = port 1, etc.)
1. If module was not intentionally disconnected,
check ribbon cables, connectors, and pins.
Replace wiring port expander, modules, Main
Control Board or complete drive as required.
2. Check OIM connection if used.
206
87 Ixo Voltage Range 4 Ixo voltage calculated from motor name-
plate data is too high
1. Press ICVC RESET key.
2. Contact Carrier Service.
206
100 Parameter Chksum 2 The checksum read from the board does
not match the checksum calculated.
1. Press ICVC RESET key to restore defaults.
2. Cycle power to the VFD.
206
101 UserSet1 Chksum 2 The checksum read from the user
set does not match the checksum
calculated.
1. Press ICVC RESET key to restore defaults.
2. Cycle power to the VFD.

102 UserSet2 Chksum 2
103 UserSet3 Chksum 2
104 Pwr Brd Chksum1 4 The checksum read from the EEPROM
does not match the checksum calcu-
lated from the EEPROM data.
1. Press ICVC RESET key to restore defaults.
2. Cycle power to the VFD.
206
105 Pwr Brd Chksum2 2 The checksum read from the board does
not match the checksum calculated.
1. Cycle power to the VFD.
2. If problem persists, contact Carrier Service.
206
106 Incompat MCB-PB 2 Drive rating information stored on the
power board is incompatible with the
Main Control board.
Load compatible version files into drive. 206
107 Replaced MCB-PB 2 Main Control board was replaced and
parameters were not programmed.
Program parameters into VFD_CONF screen. 206
120 I/O Board Mismatch 4 Incorrect I/O board identified. Program parameters into VFD_CONF screen. 206
121 I/O Board Comm
Loss
2 Loss of communication to I/O board. 1. Press ICVC RESET key.
2. Check VFD board ribbon cables and connec-
tor pins.
206
122 I/O Board Fail 4 Board failure. 1. Press ICVC RESET key, cycle power to the
VFD.
2. If fault repeats, replace I/O board.

4 High current was detected in an IGBT. 1. Check for loose connection in IGBT wire
harness.
2. Check IGBTs.
3. Check precharge resistors and fuses.
4. Check precharge contactor.
