“
SECURE DISABLE” FAULT – GENERAL INFORMATION
Importance of knowing the frequency of “Secure Disable” fault.
Depending on the frequency with witch the drive trips on “Sec. Disable”, we can consider that some
explanations are more likely than others.
•If there is a problem with the wiring, the connections, the E-stop or a problem of vibration, we can expect the
drive to trip several times a day or even an hour.
•If the drive trips only few times a week or less, the problem may come from the supply (power outage)
Every information is important and may help the us to find the root cause of the problem.
Example : if the drive trips on “sec. disable” only when running at certain speeds, that may suggest a
vibration related issue.
