Trip Warning Message
The trip display message is flashed repeatedly on the screen to warn of an imminent trip. Some trip conditions need time to
take effect. The warning can allow you time to rectify the situation.
The message will clear when you use the keypad, but after a short time will reappear until the problem is resolved, or the
drive trips.
What Happens when a Trip Occurs
When a trip occurs, the drive’s power stage is immediately disabled causing the motor and load to coast to a stop. The trip is
latched until action is taken to reset it. This ensures that trips due to transient conditions are captured and the drive is disabled,
even when the original cause of the trip is no longer present.
Keypad Indications
If a trip condition is detected the activated alarm is displayed on the MMI display.
Resetting a Trip Condition
All trips must be reset before the drive can be re-enabled. A trip can only be reset once the trip condition is no longer active,
i.e. a trip due to a heatsink over-temperature will not reset until the temperature is below the trip level.
You can reset the trip as follows:
1.
Press the
(STOP) key to reset the trip and clear the alarm from the display.
2.
Remove and then re-apply the RUN command and the drive will run normally.
In remote mode, success is indicated by displaying
