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.
Drive Indications
If a trip condition is detected the unit displays and performs the following actions.
1.
The HEALTH LED goes out indicating a Trip condition has occurred. (Investigate, find and remove the cause of the trip.)
2.
Terminal B6 (Healthy) goes low (0V).
3.
The MMI displays the activated alarm.
4.
The alarm message(s) can be acknowledged by pressing the
E
key, however, the unit will not restart at this point.
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 A trip can only be reset once the trip condition is no longer active, i.e. a trip due to a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.
NOTE
More than one trip can be active at any time. For example, it is possible for both the HEATSINK TRIP and the OVERVOLTS (VA) trips to
be active. Alternatively it is possible for the Drive to trip due to a FIELD OVER I error and then for the HEATSINK TRIP trip to become
active after the Drive has stopped (this may occur due to the thermal time constant of the heatsink).
You can reset the trip(s) in one of two ways:
1.
Power-up, or remove and re-apply the auxiliary power supply.
2.
Stop and start the drive, i.e. remove and re-apply the Start/Run signal (terminal C3 or C4, or the STOP and RUN keys on the MMI).
Success is indicated by the HEALTH LED (on the unit ) illuminating. The MMI will return to its original display.
