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condition is no longer active, i.e. a trip due to a heatsink over-temperature will not reset until the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:

2. Remove and then re-apply the RUN command and the drive will run normally.

RIPS AND
