8.1 X5 Fault Codes
When faults occur, you can access the status parameters that are saved along with the fault
(Advanced Fault history). To view these parameters, which store the drive’s status at the time of the
fault, access
Fault History by pressing SHIFT and ENTER, and select Last Fault. Press the Shift
key while viewing the last fault, and then use the
INC or DEC (up or down arrow) keys to scroll
through the stored drive status parameters. Press the
Shift key again to return to the programming
mode fault parameter.
A great deal of information is contained in the Fault History log for the last fault, and also the
previous nine faults, including the following:
Output Frequency Total Run Time DI Status Drive Status 2
Drive Load DC Bus Voltage Output Status
Drive Status Adv Fault Code Vin1 Status
Drive Warning Cntl Board Temp Cin Status
Output Voltage Drive Power Out Vin2 Status
Output Current Fault Date Vmet Status
Load Torque Fault Time Imet Status
Drive Temp Drive Warning 2 Actual Carrier

The drive is receiving EE write
requests faster than they can be

be caused by writing parameters
too frequently through Modbus.
Slow down the frequency of
Modbus writes.
