Trips
What Happens when a Trip Occurs
When a trip occurs, the Inverter’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 Inverter is disabled, even when the original
cause of the trip is no longer present
Inverter Indications
If a trip condition is detected the unit displays and performs the following actions.
1.
The HEALTH LED flashes indicating a Trip condition has occurred. (Investigate, find and
remove the cause of the trip.)
1.
The programming block SEQUENCING LOGIC::TRIPPED signal is set to TRUE.
The DIGITAL OUTPUT 1 (HEALTH) digital output changes between TRUE/FALSE,
depending on the output logic.
Operator Station Indications (when connected)
If a trip condition is detected the MMI displays and performs the following actions.
1.
The HEALTH LED on the Operator Station flashes indicating a Trip condition has
occurred and a trip message is displayed stating the cause of the trip.
2.
The programming block SEQUENCING LOGIC::TRIPPED signal is set to TRUE.
The DIGITAL OUTPUT 1 (HEALTH) digital output changes between TRUE/FALSE,
depending on the output logic.
3.
The trip message(s) must be acknowledged by pressing the
E
key. Refer to Chapter 5: “The
Operator Station” - Alert Message Displays.
Resetting a Trip Condition
All trips must be reset before the Inverter 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trip condition is no longer active, i.e. a trip due to a heatsink over-temperature will not reset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 TEMP and the LINK OVERVOLTS trips to be active. Alternatively it is possible
for the Inverter to trip due to an OVERCURRENT error and then for the HEATSINK TEMP
trip to become active after the Inverter has stopped (this may occur due to the thermal
time constant of the heatsink).
Reset the trip(s) using the remote trip reset input, or by pressing the
STOP/RESET
key on the
Operator Station.
Success is indicated by the HEALTH LED (on the unit or MMI) ceasing to flash and returning
to a healthy “ON” state. The programming block SEQUENCING LOGIC::TRIPPED output is
reset to FALSE.
