To aid in troubleshooting, Parameters 50 through 60 can be accessed without entering the PASSWORD.
Simply press the Mode button twice to “skip” over the PASSWORD prompt, and “P50” will be displayed
to indicate that the parameter menu has been entered and Parameter 50 (FAULT HISTORY) can be
viewed. The
L and M buttons can be used to scroll from Parameter 50 to Parameter 60. Once the
desired parameter is found, press the Mode button to view its “contents”. When finished, press Mode to
exit the parameter menu. An example is shown below:
Press Mode once
Display reads “00”
Upper right decimal point blinks
Press Mode again
Display reads “P50” (FAULT HISTORY)
Use L and M to scroll to the desired
parameter number
(In this example Parameter 54 has been
selected, which is MOTOR LOAD)
Press Mode to view parameter contents
(77 = 77% LOAD)
Upper right decimal point blinks
Press Mode again to exit
In the example above, Parameter 54 - MOTOR LOAD is being viewed. The “77” in the example
indicates that the load on the motor is 77% of the output current rating of the drive.
