Flashing green — alarms For less severe errors, called alarms, the diagnostic display is advisory. Alarm messages disappear from the control panel display after a few seconds. The message returns periodically as long as the alarm condition exists.

Temperature is at or above limit. Exceptionally low voltage detected on the OINT power supply.

In the process of operation of the frequency converter, sooner or later problems related to its correct operation arise. Errors and failures can occur both when turning on setting the frequency converter and during its operation. If most errors occur, the inverter stops working. The reaction to some errors can be programmed. For example, if a fault occurs the frequency converter can stop or continue to run by issuing a fault message.

The fault name is shown in long form along with some possible causes and corrective actions that may be taken. Check for and correct:. Temperature is at or above limit. Motor is operating in the stall region. Check for and. The drive monitors for ground faults while the drive is running and while the drive is not running. Detection is more sensitive when the drive is not running and can produce false positives.
