Trips and Fault Finding
What happens when a trip occurs
When a trip occurs, the drive’s power stage is immediate-
ly disabled causing the motor and load to coast to a stop.
The trip is latched until action is taken to reset it. This en-
sures 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 dis-
played 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 lon-
ger 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.
