Fault
Description
Action
41
Phase UV Short.
Excessive current has been detected between these two output terminals.
•
Check the motor and drive output terminal wiring for a shorted condition.
•
Replace drive if fault cannot be cleared.
42
Phase UW Short.
43
Phase VW Short.
48
Params Defaulted. The drive was commanded to write default values to EEPROM.
•
Clear the fault or cycle power to the drive.
•
Program the drive parameters as needed.
63
SW OverCurrent.
Programmed A486, A488 [Shear Pinx Level] has been exceeded for a time
period greater than the time programmed in A487, A489 [Shear Pin x Time].
•
Verify connections between motor and load.
•
Verify level and time requirements.
64
Drive Overload.
Drive overload rating has been exceeded.
•
Reduce load or extend Accel Time.
70
Power Unit.
Failure has been detected in the drive power section.
•
Check maximum ambient temperature has not been exceeded.
•
Cycle power.
•
Replace drive if fault cannot be cleared.
71
DSI Net Loss.
Control over the Modbus or DSI communication link has been interrupted.
•
Cycle power.
•
Check communications cabling.
•
Check Modbus or DSI setting.

Check network adapter setting.
•
Check external network status.
80
Autotune Failure. The autotune function was either cancelled by the user or failed.
•
Restart procedure.
81
DSI Comm Loss.
Communications between the drive and the Modbus or DSI master device
have been interrupted.
•
Cycle power.
•
Check communications cabling.
•
Check Modbus or DSI setting.
•
Check Modbus or DSI status.
•
Modify using C125 [Comm Loss Action].
•
Connecting I/O terminals C1 and C2 to ground may improve noise immunity.
•
Replace wiring, Modbus master device, or control module.
82
Opt Comm Loss.
Communications between the drive and the network option card have been
interrupted.
•
Cycle power.
•
Reinstall option card in drive.
•
Modify using C125 [Comm Loss Action].
•
Replace wiring, port expander, option card, or control module.
94
Function Loss.
“Freeze-Fire” (Function Loss) input is inactive, input to the programmed
terminal is open.
•
Close input to the terminal and cycle power.
100
Parameter Chksum. Drive parameter non-volatile storage is corrupted.
•
Set P053 [Reset To Defalts] to 2 “Factory Rset”.
101
External Storage. External non-volatile storage has failed.
•
Set P053 [Reset To Defalts] to 2 “Factory Rset”.
105
C Connect Err.
Control module was disconnected while drive was powered.
•
Clear fault and verify all parameter settings. Do not remove or install the control module while
power is applied.
107
Replaced C-P.
The control module could not recognize the power module. Hardware failure.
•
Change to a different power module.
•
Replace control module if changing power module does not work.
109
Mismatch C-P.
The control module was mounted to a different drive type power module.
•
Set P053 [Reset To Defalts] to 3 “Power Reset”.
110
Keypad Membrane. Keypad membrane failure / disconnected.
•
Cycle power.
•
Replace control module if fault cannot be cleared.
114
uC Failure.
Microprocessor failure.
•
Cycle power.
•
Verify grounding requirements. See General Grounding Requirements on page 20 for more
information.
•
Replace control module if fault cannot be cleared.
122
I/O Board Fail.
Failure has been detected in the drive control and I/O section.
•
Cycle power.
•
Replace drive or control module if fault cannot be cleared.
125
Flash Update Req. The firmware in the drive is corrupt, mismatched, or incompatible with the
hardware.
•
Perform a firmware flash update operation to attempt to load a valid set of firmware.
126
NonRecoverablErr. A non-recoverable firmware or hardware error was detected. The drive was
automatically stopped and reset.
•
Clear fault or cycle power to the drive.
•
Replace drive or control module if fault cannot be cleared.
127
DSIFlashUpdatReq. A critical problem with the firmware was detected and the drive is running
using backup firmware that only supports DSI communications.
•
Perform a firmware flash update operation using DSI communications to attempt to load a valid
set of firmware.
