Accessing and Clearing the Error Log
If a fault occurs, the drive displays a fault code and logs the fault code into the error
log. If more than one fault occurs, the first fault flashes on the display and the
subsequent faults (up to two) are logged in the error log. After three faults, no
subsequent faults are logged.
The faults in the error log are numbered sequentially. For example, if an overcurrent
fault occurred first followed by a thermal overload fault, the error log would read 1-OC,
2-OL.
The last fault to occur appears first when the error log is accessed. For example, if the
last fault to occur was a low bus fault, and the error log contained three entries, the
error log would display 3-LU when the error log is accessed.
The electronic thermal overload trip level has been exceeded. This fault protects the drive motor from
overheating due to excessive current within a specified period. Note that the fault will not clear until the input
line voltage is within the proper range. This may take a few seconds.
Possible Cause
Corrective Action
The current limit setting in F-05 is incorrect.
If the current limit level is too low relative to the load,
increase the current level in F-05. Refer to chapter 8
for the parameter description.
The electronic thermal overload setting in F-14
does not match the motor and drive combination.
Verify the value of F-14. Refer to chapter 8 for the
parameter description.
The power supply is out of range.
Possible Cause
Corrective Action
Possible regulator failure.
Contact Reliance Electric for assistance if the fault
reoccurs after pressing the STOP/RESET key (or
asserting the IET reset input) or cycling power.
The value in F-28 is incorrect for the drive.
Possible Cause
Corrective Action
An invalid drive voltage was selected in F-28.
Select the voltage to match the input line voltage.
