Trips and Fault Finding
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 GKP 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 A trip can only be reset once the trip condition is no longer active, i.e. a trip due to a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. In remote terminal sequencing mode, create a 0 to 1 transition on the RESET TRIP bit, (bit 7), in the App Control Word parameter.
3. In remote communications sequencing mode, create a 0 to 1 transition on the RESET TRIP bit, (bit 7), in the Comms Control Word
parameter.
